I have a UIImageView on UIView, I use code as below to draw round corner, but it doesn't work, what can I do?

Code:

    self.icon.image = [UIImage imageNamed:@"icon-72.png"];
    self.icon.layer.masksToBounds = YES;
    self.icon.layer.cornerRadius = 10.632f;

What is self?
What is icon?

Click to expand...

I found reason, that doesn't show round corner in Simulator, but show it on my iPhone4S, is this a bug about Simulator?

I wouldn't consider a bug so much as just a shortcoming of the simulator... the simulator can't run the exact same binary as the iPhone because the CPU in Mac is different from that of an iOS device. To do final software tests, always do it on an actual iOS device, not the simulator.
