Question

我试图将Facebook兼容性整合到我的游戏中，以便在游戏结束时分享您的分数。

我已按照Facebook的文档中列出的所有步骤进行操作，但我似乎无法找到导致此错误的原因或设置为nil的对象。

当我按下从以下代码生成的登录按钮时：

FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.center = self.view.center;
[self.view addSubview:loginButton];

我收到此错误：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: object cannot be nil (key: client_id)'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException

谢谢！

Answer 1

我遇到了同样的问题，但我通过检查info.plist来解决这个问题。我建议仔细检查你的拼写。它需要是FacebookAppID，我把它作为FacebookID。当我修正错字时，它运行正常。但是，您可能会遇到不同的问题。

Answer 2

我没想到这三行造成了错误。如果您提供更多的编码行，那将是很棒的。请使用以下代码进行最新的Facebook集成。

   -(void)viewDidLoad{
    FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
    [self.view addSubview:loginButton];

    self.loginButton.readPermissions = @[@"public_profile", @"email", @"user_friends"];
    self.loginButton.delegate = self;
    [FBSDKProfile enableUpdatesOnAccessTokenChange:YES];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(profileUpdated:) name:FBSDKProfileDidChangeNotification object:nil];

     }
-(void)profileUpdated:(NSNotification *) notification{
    NSLog(@"User name: %@",[FBSDKProfile currentProfile].name);
    NSLog(@"User ID: %@",[FBSDKProfile currentProfile].userID);
}

- (void)  loginButton:(FBSDKLoginButton *)loginButton
didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result
                error:(NSError *)error{

}
- (void)loginButtonDidLogOut:(FBSDKLoginButton *)loginButton{

}

在IOS应用程序中登录Facebook的对象不能为零
