解决方法
我已经解决了这个问题,添加下一个方法到app代理：
- (void)application:(UIApplication *)application willChangeStatusBarOrientation:(UIInterfaceOrientation)newStatusBarOrientation duration:(NSTimeInterval)duration {
NSArray *windows = [application windows];
for (UIWindow *nextWindow in windows) {
[[nextWindow.rootViewController class] attemptRotationToDeviceOrientation];
}
}
