方向改变后XCode UIImageView不在正确的位置

Question

我的申请表有问题。我试图让图片显示出来并让它在应用程序中的某些操作完成后2秒后淡出，这一切都正常。但是，当图片在屏幕上并且我旋转我的设备时，图片的位置不会更新到屏幕的新中心，这不是一个大问题，但它看起来非常糟糕。我在下面列出了我的代码。

+(void)fadeOut:(int)type{
//create subImageView
UIImageView *myImageView = nil;
switch (type) {
    case 1:
        myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"skipoverlay.png"]];
        break;
    case 2:
        myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checkoverlay.png"]];
        break;
    case 3:
        myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"endoftask.png"]];
        break;
    case 4:
        myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"startoverlay"]];
        break;

    default:
        break;
}
UIWindow *mainWindow = [[UIApplication sharedApplication] keyWindow];
myImageView.center=mainWindow.center;
myImageView.tag=11;
[mainWindow insertSubview:myImageView aboveSubview:mainWindow];

//add fade out animation
[UIView beginAnimations: @"Fade Out" context:nil];

// wait for time before begin
[UIView setAnimationDelay:0];

// duration of animation
[UIView setAnimationDuration:2];
myImageView.alpha = 0.0;
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(removeView)];
[UIView commitAnimations];
}
