白黑屏

Question

我使用FBConnect API ...而我使用此代码，同时按下键..

- (IBAction)postGradesTapped:(id)sender { 
_posting = YES; 
// If we're not logged in, log in first... 
if (![_session isConnected]) { 
    self.loginDialog = nil; 
    _loginDialog = [[FBLoginDialog alloc] init];  
    [_loginDialog show];  
} 
// If we have a session and a name, post to the wall! 
else if (_facebookName != nil) { 
    [self postToWall]; 
} 
// Otherwise, we don't have a name yet, just wait for that to come through. 

}

现在，当我按下按钮...

白色空白屏幕出现... :(

可以采取什么问题？

根据你的代码，登录成功后，你张贴在你的墙上。所以它可能会变成空白屏幕。尝试在登录成功时在控制台上打印某些内容
