Kakao Talk Sharing: iOS

This document describes how to integrate Kakao Talk sharing APIs into your service with the Kakao SDK for iOS (hereinafter referred to as 'iOS SDK').

Before you begin

Register iOS Platform

To use the iOS SDK, you must register the iOS platform in advance. Go to [My Application] > [Platform] and register the iOS platform by specifying the Bundle ID.

Add modules

1. Add the KakaoSDKShare(Kakao Talk sharing module) in the Podfile by referring to Set Custom URL Schemes.
2. Add the import statements for the Kakao Talk sharing module as follows.

Sample

import KakaoSDKShare

import KakaoSDKShare
import RxKakaoSDKShare

Choose an API to use

According to your service's purpose and requirements, you need to decide which API to use first by considering their characteristics and difference.

Set Custom URL Scheme

To make your app launch when a user clicks a button in the Kakao Talk sharing message, you need to set LSApplicationQueriesSchemes to "kakaolink" in the Configure build settings step. This value is used to create a Custom URL Scheme in the form of "kakao${YOUR_NATIVE_APP_KEY}://kakaolink".

You can also set additional parameters when running the app as needed by using androidExecutionParams for Android SDK or iosExecutionParams for iOS SDK. If you have defined the parameters, they are added to Custom URL Schemes as follows.

kakao${YOUR_NATIVE_APP_KEY}://kakaolink?${androidExecutionParams}
kakao${YOUR_NATIVE_APP_KEY}://kakaolink?${iosExecutionParams}

Configure a message

When you configure a Kakao Talk message through the Kakao Talk sharing message API or Kakao Talk messaging API, use one of the classes defined in KakaoSDKTemplate according to a message type by referring to Message template components. Then, create an object for the desired message type among five types, and define the message content for the template object.

Here are the code snippets showing how to configure a message for each message type.

let title = "Feed messsage"
let description = "Example of Feed messsage"

As an example, here are the steps to configure and send a Feed message.

Send message with default template

This API enables you to configure a message in JSON format according to the default template type to use and share it through Kakao Talk.

In the case of shareDefault(), define the Templatable object by calling SdkJSONDecoder.custom.decode() and passing the JSON object created in Configure a message. After that, pass the defined Templatable object when calling the Kakao Talk sharing API or Kakao Talk messaging API. You can also create the templateObject and use it when sending a message by referring to Advanced: Create a message using constructor.

To figure out if it is possible to share a message through Kakao Talk, call isKakaoTalkSharingAvailable() that checks if Kakao Talk has been installed. If Kakao Talk is installed, call shareDefault() that shares a message through Kakao Talk. If not installed, call makeDefaultUrl() to declare a URL for sharing and open the URL WebView or a default browser.

Parameter

Sample

//in ViewController
var safariViewController : SFSafariViewController? // to keep instance
//...

guard let templatable = try? SdkJSONDecoder.custom.decode(FeedTemplate.self, from: feedTemplateJsonStringData) else {
    return
}

// Check if Kakao Talk has been installed.
if ShareApi.isKakaoTalkSharingAvailable() {
    // Kakao Talk sharing is available.
    // For 'templatable', refer to the 'Configure a message' guide.
    ShareApi.shared.shareDefault(templatable: templatable) {(sharingResult, error) in
    if let error = error {
        print(error)
    }
    else {
        print("shareDefault() success.")

        if let sharingResult = sharingResult {
            UIApplication.shared.open(sharingResult.url, 
                            options: [:], completionHandler: nil)
        }
    }
}
else {
    // If Kakao Talk is not installed, it is recommended to share URI via web.
    // You can use custom webView or default browser.
    // Example of sharing URI via web
    if let url = ShareApi.shared.makeDefaultUrl(templatable: templatable) {
        self.safariViewController = SFSafariViewController(url: url)
        self.safariViewController?.modalTransitionStyle = .crossDissolve
        self.safariViewController?.modalPresentationStyle = .overCurrentContext
        self.present(self.safariViewController!, animated: true) {
            print("Succeeded in presenting web.")
        }
    }
}

// Class member property
let disposeBag = DisposeBag()

// For 'templatable', refer to the 'Configure a message' guide.
if let templatable = try? SdkJSONDecoder.custom.decode(FeedTemplate.self, from: feedTemplateJsonStringData) {
    ShareApi.shared.rx.shareDefault(templatable:templatable)
        .subscribe(onSuccess: { (sharingResult) in
            print("shareDefault() success.")
            
            UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
        }, onFailure: {error in
            print(error)
        })
        .disposed(by: disposeBag)
}

Return data

Calling shareDefault() launches the Kakao Talk application and shows the list of user's Kakao Talk friends or chatrooms. When a user selects friends or a chatroom to send the message to, the messages are sent to the selected targets.

shareDefault() returns SharingResult. Because the Kakao Talk sharing API does not inform the result of message delivery, implement the Kakao Talk sharing success callback function.

SharingResult

Send message with custom template

This API enables you to customize a template in [Tools] > [Message Template Builder] and send a message through Kakao Talk.

To figure out if it is possible to share a message through Kakao Talk, call isKakaoTalkSharingAvailable() that checks if Kakao Talk has been installed. If Kakao Talk is installed, call shareCustom() that shares a message through Kakao Talk. If not installed, call makeCustomUrl() to declare a URL for sharing and open the URL WebView or a default browser.

Parameter

Sample

let templateId : Int64 = 12345

// Check if Kakao Talk has been installed.
if ShareApi.isKakaoTalkSharingAvailable() {
    // Kakao Talk sharing is available.
    ShareApi.shared.shareCustom(templateId: templateId, templateArgs:["title":"This is title.", "description":"This is description."]) {(sharingResult, error) in
        if let error = error {
            print(error)
        }
        else {
            print("shareCustom() success.")
            if let sharingResult = sharingResult {
                UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
            }
        }
    }
}
else {
    // If Kakao Talk is not installed, it is recommended to share URI via web.
    // You can use custom webView or default browser.
    // Example of sharing URI via web
    if let url = ShareApi.shared.makeCustomUrl(templateId: templateId, templateArgs:["title":"This is title.", "description":"This is description."]) {
        self.safariViewController = SFSafariViewController(url: url)
        self.safariViewController?.modalTransitionStyle = .crossDissolve
        self.safariViewController?.modalPresentationStyle = .overCurrentContext
        self.present(self.safariViewController!, animated: true) {
            print("Succeeded in presenting web.")
        }
    }
}

// Class member property
let disposeBag = DisposeBag()

let templateId : Int64 = 12345

ShareApi.shared.rx.shareCustom(templateId:templateId, templateArgs:["title":"This is title.", "description":"This is description."])
    .subscribe(onSuccess: { (sharingResult) in
        print("shareCustom() success.")
        
        UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
    }, onFailure: {error in
        print(error)
    })
    .disposed(by: disposeBag)

Return data

Calling shareCustom() launches the Kakao Talk application and shows the list of user's Kakao Talk friends or chatrooms. When a user selects friends or a chatroom to send the message to, the messages are sent to the selected targets.

shareCustom() returns SharingResult. Because the Kakao Talk sharing API does not inform the result of message delivery, implement the Kakao Talk sharing success callback function.

Send scrap message with default template

This API scraps a web page, configures a message based on the scraped web page information, and then sends it through Kakao Talk.

To figure out if it is possible to share a message through Kakao Talk, call isKakaoTalkSharingAvailable() that checks if Kakao Talk has been installed. If Kakao Talk is installed, call shareScrap() that shares a message through Kakao Talk. If not installed, call makeScrapUrl() to declare a URL for sharing and open the URL WebView or a default browser.

Parameter

Sample

let requestUrl = "https://developers.kakao.com"

// Check if Kakao Talk has been installed.
if ShareApi.isKakaoTalkSharingAvailable() {
    // Kakao Talk sharing is available.
    ShareApi.shared.shareScrap(requestUrl: requestUrl) {(sharingResult, error) in
        if let error = error {
            print(error)
        }

        self.safariViewController?.modalTransitionStyle = .crossDissolve
        self.safariViewController?.modalPresentationStyle = .overCurrentContext
        self.present(self.safariViewController!, animated: true) {

    .subscribe(onSuccess: { (sharingResult) in
        print("shareScrap() success.")
        
        UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
    }, onFailure: {error in
        print(error)
    })
    .disposed(by: disposeBag)

Return data

Calling shareScrap() launches the Kakao Talk application and shows the list of user's Kakao Talk friends or chatrooms. When a user selects friends or a chatroom to send the message to, the messages are sent to the selected targets.

shareScrap() returns SharingResult. Because the Kakao Talk sharing API does not inform the result of message delivery, implement the Kakao Talk sharing success callback function.

Send scrap message with custom template

This API scraps a web page, configures a message based on the scraped web page information, and then sends it through Kakao Talk. You can use a custom template registered in [Tools] > [Message Template Builder] when requesting to send a scrap message.

To figure out if it is possible to share a message through Kakao Talk, call isKakaoTalkSharingAvailable() that checks if Kakao Talk has been installed. If Kakao Talk is installed, call shareScrap that shares a message through Kakao Talk. If not installed, call makeScrapUrl to declare a URL for sharing and open the URL WebView or a default browser.

Parameter

Sample

let requestUrl = "https://developers.kakao.com"
let templateId : Int64 = 12345

// Check if Kakao Talk has been installed.
if ShareApi.isKakaoTalkSharingAvailable() {
    // Kakao Talk sharing is available.
    ShareApi.shared.shareScrap(requestUrl: requestUrl, templateId: templateId) {(sharingResult, error) in
    if let error = error {
        print(error)
    }
    else {
        print("shareScrap() success.")
        if let sharingResult = sharingResult {
            UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
        }
    }
}
else {
    // If Kakao Talk is not installed, it is recommended to share URI via web.
    // You can use custom webView or default browser.
    // Example of sharing URI via web
    if let url = ShareApi.shared.makeScrapUrl(requestUrl: requestUrl, templateId: templateId) {
        self.safariViewController = SFSafariViewController(url: url)
        self.safariViewController?.modalTransitionStyle = .crossDissolve
        self.safariViewController?.modalPresentationStyle = .overCurrentContext
        self.present(self.safariViewController!, animated: true) {
            print("Succeeded in presenting web.")
        }
    }
}

// Class member property
let disposeBag = DisposeBag()

let requestUrl = "https://developers.kakao.com"
let templateId : Int64 = 12345


ShareApi.shared.rx.shareScrap(requestUrl: requestUrl, templateId: templateId)
    .subscribe(onSuccess: { (sharingResult) in
        print("shareScrap() success.")
        
        UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
    }, onFailure: {error in
        print(error)
    })
    .disposed(by: disposeBag)

Return data

Calling shareScrap() launches the Kakao Talk application and shows the list of user's Kakao Talk friends or chatrooms. When a user selects friends or a chatroom to send the message to, the messages are sent to the selected targets.

shareScrap() returns SharingResult. Because the Kakao Talk sharing API does not inform the result of message delivery, implement the Kakao Talk sharing success callback function.

Set Kakao Talk sharing success callback

The Kakao Talk sharing success callback is a function to send a callback request to the URL specified on Kakao Developers when a Kakao Talk sharing message is successfully sent to friends or a chatroom selected by a user. This function is only available for Kakao Talk sharing API, not for Kakao Talk messaging API.

To use this feature, you need to:

1. Set the callback URL and request method by referring to Prerequisites > Set Kakao Talk sharing success callback.
2. Build a server to receive a Kakao Talk sharing success callback.
3. Set a custom parameter to pass additional information when requesting the Kakao Talk sharing API.
4. Implement a process to handle the callback delivered to your service server's callback URL.

To use the Kakao Talk sharing success callback function, you must specify a custom parameter through serverCallbackArgs. Otherwise, you cannot receive Kakao Talk sharing success callbacks even though you registered a callback URL for Kakao Talk sharing in [My Application]. When your service server receives a Kakao Talk sharing success callback, you can figure out additional information through the predefined custom parameters, such as what content the user has shared.

To pass additional information when requesting the Kakao Talk sharing API, declare serverCallbackArgs, and pass keys and values as a Dictionary. Here is a code snippet showing how to set parameters for Kakao Talk sharing success callback.

Sample

// Template ID.
let templateId : Int64 = 12345;
// Template arguments.
let templateArgs = ["title": "This is the title area.", "description": "This is the description area."]
// Information passed from Kakao server. 
let serverCallbackArgs = ["user_id": "abcd", "product_id": "1234"]

// Check if Kakao Talk has been installed.
if ShareApi.isKakaoTalkSharingAvailable() {
    // Kakao Talk sharing is available.
    ShareApi.shared.shareCustom(templateId:templateId,
                            templateArgs:templateArgs,
                            serverCallbackArgs: serverCallbackArgs) { (sharingResult, error) in
        if let error = error {
            print(error)
        }
        else {
            print("shareCustom() success.")
            if let sharingResult = sharingResult {
                UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
            }
        }
    }
}
else {
    // If Kakao Talk is not installed, it is recommended to share URI via web.
    // You can use custom webView or default browser.
    // Example of sharing URI via web
    if let url = ShareApi.shared.makeCustomUrl(templateId:templateId,
                                                    templateArgs:templateArgs,
                                                    serverCallbackArgs: serverCallbackArgs) {
        self.safariViewController = SFSafariViewController(url: url)
        self.safariViewController?.modalTransitionStyle = .crossDissolve
        self.safariViewController?.modalPresentationStyle = .overCurrentContext
        self.present(self.safariViewController!, animated: true) {
            print("Succeeded in presenting web.")
        }
    }
}

// Class member property
let disposeBag = DisposeBag()

// Template ID
let templateId : Int64 = 12345;
// Template arguments
let templateArgs = ["title": "This is the title area.", "description": "This is the description area."]
// Information passed from Kakao server.
let serverCallbackArgs = ["user_id": "abcd", "product_id": "1234"]

ShareApi.shared.rx.shareCustom(templateId:templateId,
                            templateArgs:templateArgs,
                            serverCallbackArgs: serverCallbackArgs)
    .subscribe(onSuccess: { (sharingResult) in
        print("shareCustom() success.")
        
        UIApplication.shared.open(sharingResult.url, options: [:], completionHandler: nil)
    }, onFailure: {error in
        print(error)
    })
    .disposed(by: disposeBag)
}

If the Kakao Talk sharing message is successfully sent, Kakao sends a Kakao Talk sharing success callback including the specified parameters to the callback URL of your service server. For more information on the callback request, refer to Reference Information > Kakao Talk sharing success callback.

Upload image

You can attach images to a Kakao Talk sharing message by passing an image URL when configuring a message template or uploading images in the Message template builder in advance. To use the image file stored on your device for a message, you must upload the image file to the server first to obtain its URL value.

If it is difficult to obtain the image file URL, you can either upload an image file to the Kakao Talk sharing server or scrap it. The images uploaded to the Kakao Talk sharing server are stored for up to 20 days and automatically deleted after the period.

Uploading image

To upload an image, call the imageUpload() method defined in ShareApi. You can only upload an image with a file size of 2 MB or less.

Parameter

Sample

if let image = UIImage(named: "sample1") {
    ShareApi.shared.imageUpload(image:image) { [weak self] (imageUploadResult, error) in
        if let error = error {
            print(error)
        }
        else {
            print("imageUpload() success.")
        }
    }
}

// Class member property
let disposeBag = DisposeBag()

if let image = UIImage(named: "sample1") {
    ShareApi.shared.rx.imageUpload(image:image)
        .subscribe(onSuccess: { (imageUploadResult) in
            print("imageUpload() success.")
            
        }, onFailure: {error in
            print(error)
        })
        .disposed(by: disposeBag)
}

Scraping image

To use an image by scraping an image uploaded on the web page, call the imageScrap() method defined in ShareApi.

Parameter

Sample

if let url = URL(string:"https://t1.kakaocdn.net/kakaocorp/Service/KakaoTalk/pc/slide/talkpc_theme_01.jpg") {
    ShareApi.shared.imageScrap(imageUrl: url, completion: { [weak self] (imageUploadResult, error) in
        if let error = error {
            print(error)
        }
        else {
            print("imageUpload() success.")
        }
    })
}

// Class member property
let disposeBag = DisposeBag()

if let url = URL(string:"https://t1.kakaocdn.net/kakaocorp/Service/KakaoTalk/pc/slide/talkpc_theme_01.jpg") {
    ShareApi.shared.rx.imageScrap(imageUrl: url)
        .subscribe(onSuccess: { (imageUploadResult) in
            print(String(describing:imageUploadResult))            
        }, onFailure: {error in
            print(error)
        })
        .disposed(by: disposeBag)
}

Return data

When the request is successful, the information of the uploaded image is returned. You can use the image URL when configuring a message.

Advanced: Create a message using constructor

You can also creat a message by using a constructor for a template class, as well as configuring a message in JSON format according to message types. With the method using a constructor, you can identify and define components more explicitly. However, you cannot use a template class for each message type directly when requesting to send a message. Instead, you should use it to create the templateObject object to be passed as a parameter(or argument).

Legacy

To see how to use the Messaging APIs using the Legacy Kakao SDK for iOS, see Message guide for Legacy iOS SDK.

It is highly recommended to migrate to the new version of iOS SDK as soon as possible because the Legacy version may not be supported anymore.
