Corner radius issue with UIButton

问题

I want to add a corner radius to a UIButton. It is working fine but a problem occurs when I add image to it.

It does not round its corners with images, the image is shown in full rectangle form.

Please see the image, I have used the corner radius with red color and the output is as follow:

Please help.

回答1:

Did you try to use set the masksToBounds: property? Fore example:

CALayer *layer = [myView layer];
[layer setMasksToBounds:YES];
[layer setCornerRadius:8.0];

That should do the trick.

回答2:

you use -

myButton.imageView.layer.cornerRadius = 5;

but make sure that your image size is exact same as button size. its working for me.

回答3:

yourButton.layer.cornerRadius = 10 //this value should be half of your button's height to make a circle
yourButton.clipsToBounds = true //this clips everything outside of bounds
