问题描述
当我使用标准显示模式且设备处于横向模式时，我的iPhone 6上的 UIMenuController 出现问题。在iPhone 6 Plus上，两种模式都存在问题。也许这取决于屏幕分辨率。
I have a problem with the UIMenuController on my iPhone 6 when I use the standard display mode and device is in landscape mode. On iPhone 6 Plus the problem is in both modes. Maybe it's depends on screen resolution.
在这种情况下， UIMenuController 将被左右和/或右截断。似乎 UIMenuController 可以具有最大界限，就像手机处于纵向模式一样。
In that case, the UIMenuController will be truncated left and/or right. It seems that the UIMenuController can have maximum bounds as if the phone is in portrait mode.

对我来说，这似乎是一个iOS8 + iPhone 6的错误。代码没有改变很长时间并且有效。
在缩放显示模式下， UIMenuController 将像所有其他iPhone / iPad上一样正确显示。 iOS7。
For me it seems like an iOS8+iPhone 6 bug. The code didn't change for a long time and worked.In zoomed display mode, UIMenuController will be displayed correctly like on all other iPhones/iPads incl. iOS7.
... define UIMenuItems....
[self becomeFirstResponder]; // canBecomeFirstResponder returns YES;
UIMenuController *menu = [UIMenuController sharedMenuController];
[menu setMenuItems:items];
.. define frame...
[menu setTargetRect:frame inView:self];
[menu setMenuVisible:YES animated:YES];

推荐答案
原因是你没有iPhone 6和iPhone 6+的启动图像。
The reason is that you didn't have launch images for iPhone 6 and iPhone 6+.
添加启动图像时遇到的另一件事是，使用资产目录执行此操作时会出现错误。我在我的项目中添加了静态启动图像，并按照此处的说明手动编辑了我的info.plist：。
One other thing that I ran into when adding the launch images, is that there is a bug when doing this with an asset catalog. I added static launch images to my project and manually edited my info.plist as described here: https://stackoverflow.com/a/25960203/378179.
