Facebook iOS登录 - 未调用委托方法

Question

我正在尝试为我的一个应用程序实现Facebook登录,并且没有调用委托方法 - fbDidLogin:/ application: handleOpenURL:/ fbDidNotLogin:.这是我正在使用的代码.任何帮助深表感谢!

- (void)viewDidLoad
{
    ... 
    facebook = [[Facebook alloc] initWithAppId:kFacebookAppId];
}

-(IBAction) loginWithFacebook:(id)sender {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }
    if (![facebook isSessionValid]) {
        NSArray* permissions =  [[NSArray arrayWithObjects:
                              @"email", nil] retain];
        [facebook authorize:permissions delegate:self];
    }
}

#pragma mark - Facebook delegate

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    return [facebook handleOpenURL:url]; 
}

- (void)fbDidLogin {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize]; 
}

-(void) fbDidNotLogin:(BOOL)cancelled {

}

-(void) fbDidLogout {

}

我info.plist在相应条目下的文件中也有Facebook App ID .我在loginWithFacebook:方法中有突破点并且成功击中.该[facebook authorize:]方法也被调用.

谢谢,

哎呀,我刚刚意识到这个application: handleOpenURL:方法是iOS应用程序委托方法.我在其中一个UIViewControllers中使用过它.将它移动到正确的位置,它的工作原理.
