How to round the corners of a button

Question

I have a rectangle image (jpg) and want to use it to fill the background of a button with rounded corner in xcode.

I wrote the following:

UIButton *b         


        

Answer 1

Swift 4 Update

I also tried many options still i wasn't able to get my UIButton round cornered. I added the corner radius code inside the viewDidLayoutSubviews() Solved My issue.

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = anyButton.frame.height / 2
    }

Also we can adjust the cornerRadius as follows

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = 10 //Any suitable number as you prefer can be applied 
    }
