IPhone Development notes (7) using Layer to create a rounded button

There are many ways to create a button with rounded corners. Here we only introduce the method of using Layer, which makes the efficiency of the layer unsatisfactory, but there is absolutely nothing to say about the effect.

The following code uses imageView and a transparent button. I have not modified the layer of the button directly, but the principle should be similar.

First look

UIImageView * imageView1 = [[UIImageView alloc] init];
ImageView1.frame = CGRectMake (23.75, 16.6, 75, 75 );
ImageView1.image = [UIImage imageNamed: @ "menu1.png"];
ImageView1.layer. MasksToBounds = YES;
ImageView1.layer. cornerRadius = 10.0;
ImageView1.layer. borderWidth = 2;
ImageView1.layer. borderColor = [[UIColor colorWithRed: 161/255. 0 green: 47/255. 0 blue: 47/255. 0 alpha: 1] CGColor];
