问题描述
从 iOS 8 开始，我的应用程序运行良好，但在测试此应用程序时发现了一个问题.它只会发生在 iPad 上，并且只有在我以横向模式启动应用程序时才会发生.如果它以纵向启动，一切正常(没有旋转问题).如果我旋转设备(模拟器或真实设备)，视图会旋转出屏幕，只显示真实视图的剪辑，其余部分为黑色.
since iOS 8 my App runs quite good, but I found a Problem while testing this app. It just happens on iPad and only if I launch the app in landscape mode. If it launches in Portrait everything is right(no rotation issues). If i rotate the Device (simulator or real device) the view rotates out of the screen and just shows a Cut of the real view and the rest is black.
还有其他人注意到这样的错误吗?我该如何解决?
Anyone else did notice such a bug? How can I fix it?
推荐答案
遇到了类似的问题.令人惊讶的是，修复方法是在 Appdelegate 上注释掉所有与 self.window 相关的代码.
Had similar problem. Surprisingly the fix was to comment out all the code related to self.window on Appdelegate.
注释了 self.window 的初始化及其赋值.通过选中是初始视图控制器"复选框，在属性检查器的情节提要中设置初始视图.
Commented initialising of self.window and its assignment. Set the initial view in storyboard in Attributes inspector by checking "Is Initial View Controller" checkbox.
新的更好的解决方案
评论 self.window 导致了其他问题.相反，下面的代码是最好的:
New Better Solution
Commenting self.window was causing other issues. Instead the below code is best:
- (void)applicationDidChangeStatusBarOrientation:(NSNotification *)notification
{
[UIViewController attemptRotationToDeviceOrientation];
}
