TGPassportKit — Telegram Passport SDK for iOS & macOS

TGPassportKit helps you easily integrate Telegram Passport requests into your iOS & macOS apps.

Installation

Installing using Cocoapods

To install TGPassportKit via Cocoapods add the following to your Podfile:

target 'MyApp' do
pod 'TGPassportKit' 
end

then run pod install in your project root directory.

Installing using Carthage

Add the following line to your Cartfile:

github "telegrammessenger/TGPassportKit"

then run carthage update, and you will get the latest version of TGPassportKit in your Carthage folder.

Project Setup

Configure Your Info.plist

Configure your Info.plist by right-clicking it in Project Navigator, choosing Open As > Source Code and adding this snippet:
Replace {bot_id} with your value

<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>tgbot{bot_id}</string>
</array>
</dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
<string>tg</string>
</array>

Connect AppDelegate methods

Add this code to your UIApplicationDelegate implementation

#import <TGPassportKit/TGPAppDelegate.h>

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
    BOOL handledByPassportKit = [[TGPAppDelegate sharedDelegate] application:application
                                                                     openURL:url
                                                                     options:options];
    return YES;
}

If you support iOS 9 and below, also add this method:

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url 
  sourceApplication:(nullable NSString *)sourceApplication 
         annotation:(id)annotation {
    BOOL handledByPassportKit = [[TGPAppDelegate sharedDelegate] application:application
                                                                     openURL:url
                                                           sourceApplication:sourceApplication
                                                                  annotation:annotation];
    return YES;
}

Usage

Add Telegram Passport Button

To add the Telegram Passport button, add the following code to your view controller:
Replace {bot_id}, {bot_public_key} and {request_nonce} with your values

#import <TGPassportKit/TGPButton.h>

@interface ViewController <TGPButtonDelegate>

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    TGPButton *button = [[TGPButton alloc] init];
    button.botConfig = [[TGPBotConfig alloc] initWithBotId:{bot_id} 
                                                 publicKey:@"{bot_public_key}"];
    button.scope = [[TGPScope alloc] initWithJSONString:@"{\"data\":[\"id_document\",\"address_document\",\"phone_number\"],\"v\":1}"];
    // You can also construct a scope using provided data type classes like this: 
    // button.scope = [[TGPScope alloc] initWithTypes:@[[[TGPPersonalDetails alloc] init], [[TGPIdentityDocument alloc] initWithType:TGPIdentityDocumentTypePassport selfie:true translation:true]]];
    button.nonce = @"{request_nonce}";
    button.delegate = self;
    [self.view addSubview:button];
}

- (void)passportButton:(TGPButton *)passportButton 
 didCompleteWithResult:(TGPRequestResult)result 
                 error:(NSError *)error {
    switch (result) {
        case TGPRequestResultSucceed:
            NSLog(@"Succeed");
            break;

        case TGPRequestResultCancelled:
            NSLog(@"Cancelled");
            break;

        default:
            NSLog(@"Failed");
            break;
    }
}

@end

...or Implement Your Own Behavior

If you want to design a custom UI and behavior, you can invoke a Passport request like this:
Replace {bot_id}, {bot_public_key} and {request_nonce} with your values

#import <TGPassportKit/TGPRequest.h>

- (void)performPassportRequest {
    TGPBotConfig *botConfig = [[TGPBotConfig alloc] initWithBotId:{bot_id} 
                                                        publicKey:@"{bot_public_key}"];
    TGPRequest *request = [[TGPRequest alloc] initWithBotConfig:botConfig];
    [request performWithScope:[[TGPScope alloc] initWithJSONString:@"{\"data\":[\"id_document\",\"phone_number\"],\"v\":1}"]
                        nonce:@"{request_nonce}" 
            completionHandler:^(TGPRequestResult result, NSError * _Nullable error) {
        switch (result) {
            case TGPRequestResultSucceed:
                NSLog(@"Succeed");
                break;

            case TGPRequestResultCancelled:
                NSLog(@"Cancelled");
                break;

            default:
                NSLog(@"Failed");
                break;
        }
    }];
}
