嗨，我在 Xib 文件中的 Xcode 4.6 上的应用程序中使用了类似的功能，但单击 facebook 时未登录。而在另一边，当我在故事板的另一个应用程序中登录时，它是登录。如果有人知道，请指导我。

- (id)initWithCoder:(NSCoder *)aDecoder {
    if (self = [super initWithCoder:aDecoder]) {
        _facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self];
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.facebookLikeView.href = [NSURL URLWithString:@"http://sis.uol.edu.pk/sis/MainForms/login.aspx"];
    self.facebookLikeView.layout = @"button_count";
    self.facebookLikeView.showFaces = NO;
    //    self.facebookLikeView.alpha = 1;
    [self.facebookLikeView load];
    facebookLikeView.delegate = self;
}

#pragma mark FBSessionDelegate methods

- (void)fbDidLogin {
    self.facebookLikeView.alpha = 1;
    [self.facebookLikeView load];
}

- (void)fbDidLogout {
    self.facebookLikeView.alpha = 1;
    [self.facebookLikeView load];
}

#pragma mark FacebookLikeViewDelegate methods

- (void)facebookLikeViewRequiresLogin:(FacebookLikeView *)aFacebookLikeView {
    [_facebook authorize:[NSArray array]];
}

- (void)facebookLikeViewDidRender:(FacebookLikeView *)aFacebookLikeView {
    [UIView beginAnimations:@"" context:nil];
    [UIView setAnimationDelay:0.5];
    self.facebookLikeView.alpha = 1;
    [UIView commitAnimations];
}

- (void)facebookLikeViewDidLike:(FacebookLikeView *)aFacebookLikeView {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Liked"
                                                    message:@"You liked  my app. Thanks!"
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil] ;
    [alert show];
}

- (void)facebookLikeViewDidUnlike:(FacebookLikeView *)aFacebookLikeView {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unliked"
                                                    message:@"You unliked my app ."
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil] ;
    [alert show];
}

您的代码似乎没问题，并且您正在使用FacebookLikeView的代码，当我尝试在我的应用程序中实现相同的代码时，它不会显示登录，因为我忘记将FacebookLikeView与 IB 绑定。我也遇到的另一个问题是，您可能需要_facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self]; 从方法中删除行init并将其放入viewDidLoad如下所示，因为在我的情况下它不会被调用！

if(!_facebook)
{
    _facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self];
}

我相信您不会忘记为FBConnect,FacebookLikeViewDelegate和FBSessionDelegate

如果您仍然无法解决问题，那么可能是您Facebook App ID尝试使用源代码中提供的默认应用程序 ID，它应该可以工作！
