The main window is best found using UIWindow * mainWindow = [UIApplication sharedApplication].windows.firstObject;
最好使用主窗口找到 UIWindow * mainWindow = [UIApplication sharedApplication].windows.firstObject;
Using keyWindowcan return a keyboard or UIAlertView window, which lie above your application window.
使用keyWindow可以返回一个键盘或 UIAlertView 窗口，它位于您的应用程序窗口上方。

If you have a pointer to some subview in the window, you can easily access its window:
如果您有指向窗口中某个子视图的指针，则可以轻松访问其窗口：
UIWindow *window = mySubview.window;

Simply clever, works from any class:
非常聪明，适用于任何课程：
[(YourAppDelegate *)[[UIApplication sharedApplication] delegate] window];
Note: don't forget to import your appDelegate class
