我正在尝试为UITextField创建自定义键盘,此inputView的背景应该是透明的,我已将视图的xib文件中的背景颜色设置为"clear color".它在iOS 6及更早版本上运行良好..但在iOS 7上它不起作用任何想法我怎样才能使它工作？我希望它完全透明

我开发一个iPhone应用程序,我希望能够列出谁连接到我的应用程序和访问他们的电子邮件,如果他们已经给予我到他们的电子邮件应用程序访问用户的好友.

这是我用来打开Facebook会话的代码:

    - (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {

     NSArray *permissions = [[NSArray alloc] initWithObjects:
                    @"email",
                    nil];

    return [FBSession openActiveSessionWithReadPermissions:permissions
                                      allowLoginUI:allowLoginUI
                                 completionHandler:^(FBSession *session,
                                                     FBSessionState state,
                                                     NSError *error) {
                                     [self sessionStateChanged:session
                                                         state:state
                                                         error:error];
                                 }];
}

此外,在ViewController.m中,我使用以下代码列出朋友并获取他们的电子邮件:

    NSString *query =
         [NSString stringWithFormat:@"SELECT name, uid, pic_small, birthday,proxied_email, contact_email , email FROM user WHERE is_app_user = 1 and uid IN (SELECT uid2 FROM friend where uid1 = %@) order by concat(first_name,last_name) asc", my_fb_uid ];

        // Set up the query parameter
       NSDictionary *queryParam =
      [NSDictionary dictionaryWithObjectsAndKeys:query, @"q", nil];
       // …
