【问题描述】：

我正在尝试将 fb 和新的 google 登录功能集成到一个应用中，但遇到了某些问题，有人可以帮忙吗？

实际上我在 AppDelegate.m 中写了这个。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 

    NSError* configureError;
    [[GGLContext sharedInstance] configureWithError: &configureError];
    NSAssert(!configureError, @"Error configuring Google services: %@", configureError);

    [GIDSignIn sharedInstance].delegate = self;

    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];


- (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];

然后我在另一个类中创建谷歌登录按钮

- (void)viewDidLoad 
    [super viewDidLoad];

    fbLogingButton = [[FBSDKLoginButton alloc]init];
    fbLogingButton.delegate = self;
    fbLogingButton.center = self.view.center;
    [self.view addSubview:fbLogingButton];
    fbLogingButton.readPermissions =
    @[@"public_profile", @"email", @"user_friends"];

    googleSignInButton = [[GIDSignInButton alloc]initWithFrame:CGRectMake(120, 370,50, 150)];
    [self.view addSubview:googleSignInButton];


    [GIDSignIn sharedInstance].uiDelegate = self;

    // Do any additional setup after loading the view, typically from a nib.

但应用程序在启动时崩溃

[[GGLContext sharedInstance] configureWithError: &configureError];

如果我评论说如果我点击登录按钮就会崩溃

崩溃日志显示

【问题讨论】：

错误显示您没有为 google 登录分配 clientID：developers.google.com/+/mobile/ios/sign-in

【参考方案1】：

将此用于 Facebook https://developers.facebook.com/docs/ios/getting-started

将此用于 GooglePlus https://developers.google.com/+/mobile/ios/getting-started

必须遵循所有步骤

最后在 AppDelegate.m

- (BOOL) application:(UIApplication *) application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
BOOL wasHandled=false;;
if ([url.scheme hasPrefix:@"fb"]) 

      wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
    //Facebook callback

else       //Google Plus callback

  wasHandled=  [GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation];



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

return wasHandled;

它会工作的。谢谢你
