と私は、このコード

GIDSignIn *sigNIn=[GIDSignIn sharedInstance]; 
[sigNIn setDelegate:self]; 
[sigNIn setUiDelegate:self]; 
sigNIn.shouldFetchBasicProfile = YES; 

sigNIn.scopes = @[@"https://www.googleapis.com/auth/userinfo.email",@"https://www.googleapis.com/auth/userinfo.profile"]; 
sigNIn.clientID =@"851647387203-6n9vm1jpn8uv2c0g1qsrdi4nn69f8rh5.apps.googleusercontent.com"; 
[sigNIn signIn]; 

AppDelegate

で

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {   

    BOOL wasHandled=false; 
    if ([url.scheme hasPrefix:@"fb"]) { 

     wasHandled = [[FBSDKApplicationDelegate sharedInstance] application:application 
                    openURL:url 
                  sourceApplication:sourceApplication 
                   annotation:annotation 
         ]; 

     //Facebook callback 
    } 
    else  //Google Plus callback 
    { 
     wasHandled= [[GIDSignIn sharedInstance] handleURL:url 
             sourceApplication:sourceApplication 
               annotation:annotation]; 

    } 

    NSLog (@"application openURL"); 
    NSLog (@"URL = %@", url); 
    NSLog (@"Application = %@", sourceApplication); 

    return wasHandled; 
} 

を使用してカスタムログインを作成

Answer 1

代理人GIDSignInDelegateの方法をpinakinAudioListViewControllerに実装するだけです。

- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error { 
    NSLog(@"User signed in!"); 
} 

signIn:didDisconnectWithUser:withError:も忘れずに実装してください。

Answer 2

は、あなたのViewControllerにGIDSignInDelegateメソッドを実装します。

- (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error 
{ 
    [SVProgressHUD dismiss]; 
} 
- (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController 
{ 
    [self presentViewController:viewController animated:YES completion:nil]; 
} 
- (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController 
{ 
    [self dismissViewControllerAnimated:YES completion:nil]; 
} 
- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error 
{ 
    NSLog(@"%@",user); 
} 

また、あなたはあなたのAppDelegateクラスにこのメソッドを書くことができます。これはあなたの助けを借りた

- (BOOL)application:(UIApplication *)application 
      openURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceApplication 
     annotation:(id)annotation 
{ 
    return ([[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation]) || ([[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation]); 
} 

希望を。
