问题描述
我已添加此代码用于呈现 UIActivityViewController ：
I have added this code for presenting a UIActivityViewController:
-(IBAction)activityAction:(id)sender
{
UIActivityViewController *activityViewController = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:@"Hello Welcome!",[UIImage imageNamed:@"scene3.jpg"],nil] applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypePostToFacebook, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo, UIActivityTypeAssignToContact];
[self presentViewController:activityViewController animated:YES completion:nil];
}
Facebook，Twitter和微博图标未在iOS7中显示。在iOS6中，所有图标都正确显示。请参见下面的屏幕截图：
Facebook, Twitter and Weibo icons are not showing in iOS7. In iOS6, all the icons are showing correctly. See the screenshot below:

推荐答案
你可能未在设备设置中登录Facebook或Twitter。除非用户登录，否则它们不会显示在此处。向Apple提交错误。
You're probably not logged in to Facebook or Twitter in the devices Settings. They won't show up here unless the user is logged in. File a bug with Apple.
