Question

I’d like to be able to draw my UIImageView‘s frame in red so I can see it while I rotate and scale it. Setting the layer border width and color is not what I need because if I rotate it, it’ll rotate the layer as well (whereas the UIImageView frame doesn’t get rotated). Is this even possible? Anyone have any clue on how to do this?

Answer 1

place it on a bigger UIView that has red background color.

UIView *redBackgroundView = [[UIView alloc] initWithFrame: … /* a bigger frame than imageView*/)];
[redBackgroundView: addSubview: imageview];
[self.view addSubview: redBackgroundView];
