Facebook UIActivityViewController缺少取消和发布按钮 [英] Facebook UIActivityViewController is Missing the Cancel and Post Buttons

问题描述

当我的应用程序打开Facebook UIActivityViewController 时，Facebook屏幕顶部没有导航栏，也没有取消或发布按钮 - 退出的唯一方法屏幕是杀死应用程序。我看到的其他应用程序在Facebook屏幕的顶部有一个额外的导航栏，其中包含取消和发布按钮。

When my app opens the Facebook UIActivityViewController, there is no navigation bar at the top of the Facebook screen and there is no Cancel or Post button - the only way to exit the screen is to kill the app. Other apps that I look at have an additional navigation bar at the top of the Facebook screen, which holds the Cancel and Post buttons.

这是我正在使用的代码：

Here is the code I am using:

        NSURL *url = [NSURL URLWithString:@"http://www.mywebsite.com"];
        NSArray *activityItems = @[url];

        // Put together the UIActivityViewController
        UIActivityViewController *activityVC = [[UIActivityViewController alloc]
                                                initWithActivityItems:activityItems
                                                applicationActivities:nil];

        activityVC.excludedActivityTypes = @[UIActivityTypePrint,
                                             UIActivityTypeCopyToPasteboard,
                                             UIActivityTypeAssignToContact,
                                             UIActivityTypeSaveToCameraRoll,
                                             UIActivityTypeAirDrop,
                                             UIActivityTypePostToVimeo,
                                             UIActivityTypePostToFlickr,
                                             UIActivityTypeAddToReadingList];

        // Present the UIActivityViewController
        [self presentViewController:activityVC
                           animated:YES
                         completion:nil];

Twitter，电子邮件和短信屏幕均按预期显示。 Facebook是唯一一个遇到问题的人。

The Twitter, Email, and SMS screens all appear as expected. Facebook is the only one that is having problems.

其他一些注意事项：我注意到当我在这个应用程序上打开Facebook Share时，状态栏变为黑色，带有白色文本。在我创建的另一个测试应用程序上，状态栏看起来呈灰色，带有黑色文本。不知道为什么/这是什么意思，但可能是一个线索。

Some other notes: I notice that when I open the Facebook Share on this app, the status bar turn black with white text. On another test app that I created, the status bar looks grayed-out with black text. Not sure why / what this points to, but might be a clue.

这个问题似乎是应用范围的，因为我有3个点可以调用共享，并且它发生在所有3个实例中。

This problem seems to be app-wide, as I have 3 spots where sharing can be invoked, and it is happening in all 3 instances.

附加图像。 To：Public工具栏上方应该有一个导航栏。

Attaching an image. There should be a Navigation bar above the "To: Public" toolbar.

任何想法都将不胜感激。

Any ideas would be appreciated.

推荐答案

我创建了新的应用程序，并在按钮操作上复制粘贴代码。这是完美的工作。您可以在此处查看图片： https://drive.google。 com / file / d / 0B0FNcjA1N299NWdmZGZQWC1KbzA / view？usp = sharing

I have created new app and copy pasted your code on button action. It is workiing perfectly. You can check image of it over here: https://drive.google.com/file/d/0B0FNcjA1N299NWdmZGZQWC1KbzA/view?usp=sharing

据我所知，如果你做了一些 [ UINavigationBar外观] 在你的应用程序中，然后只有它出现问题。请检查一下。

As per my knowledge, If you have done something with [UINavigationBar appearance] in your app, then and then only it makes the problem. Please check that.
