CGAffineTransformMakeRotation UIImageView

I have an UIImageView and I wanted to rotate it slightly in the anti-clock direction. But when I do that, rotation works. But the edges are not shared. Having a pixelated edges. How do I solve this issue. Please help.

UIImageView *popupTop = [[UIImageView alloc] initWithFrame:CGRectMake(10, 54, 300, 15)];
popupTop.image = [UIImage imageNamed:@"pover_note.png"];
[self.view addSubview:popupTop];

popupTop.transform = CGAffineTransformMakeRotation(-0.04);

If you don't want a potential performance hit or possible other side effects of UIViewEdgeAntialiasing then the easiest way is to make a border of transparent pixels around your image :)

There is a key that you can set in Info.plist that enables antialiasing of the edges: UIViewEdgeAntialiasing .
