ios4 - 根据 UIWindow 方向旋转 UIImageView？

Question

我在 UIWindow 的底部有一个 UIImageView。我希望它始终在底部显示它，无论方向是什么，但在实现它时遇到了麻烦。有什么解决方案吗？

Answer 1

NSLog(@"rotate");

if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)){
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; 

    // Rotate 90 degrees to hide it off screen
    CGAffineTransform rotationTransform = CGAffineTransformIdentity;
    rotationTransform = CGAffineTransformRotate(rotationTransform,DegreesToRadians(0));
    delegate.imgV.transform = rotationTransform;

}
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation)){
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; 

    // Rotate 90 degrees to hide it off screen
    CGAffineTransform rotationTransform = CGAffineTransformIdentity;
    rotationTransform = CGAffineTransformRotate(rotationTransform,DegreesToRadians(90));
    delegate.imgV.transform = rotationTransform;

}
