成功登陆Google后，App在IOS崩溃（目标C）

Question

我正在使用Xcode 8.0，在iOS 10.0上测试并使用手动安装的SDK，GoogleSignIn / GoogleSignIn.h。

成功登录后，应用程序崩溃。我在下面提到的错误消息

错误：

我使用此代码创建了自定义登录

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];

在AppDelegate中

- (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;
}

Answer 1

只需在你的pinakinAudioListViewController实现signIn:didSignInForUser:withError:委托GIDSignInDelegate方法。

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

请不要忘记实现signIn:didDisconnectWithUser:withError:

另请参阅： https ： //developers.google.com/identity/sign-in/ios/api/protocol_g_i_d_sign_in_delegate-p

Answer 2

为您的ViewController实现GIDSignInDelegate方法：

- (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);
}

您也可以将此方法写入AppDelegate类：

- (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]);
}

希望这对你有帮助。
