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

Try my code. Here you can set all properties of UIButton like text colour, background colour, corner radius, etc.

extension UIButton {
    func btnCorner() {
        layer.cornerRadius = 10
        clipsToBounds = true
        backgroundColor = .blue
    }
}

Now call like this

yourBtnName.btnCorner()

Answer 2

If you want a rounded corner only to one corner or two corners, etc... read this post:

[ObjC] – UIButton with rounded corner - http://goo.gl/kfzvKP

It's a XIB/Storyboard subclass. Import and set borders without write code.

Answer 3

I tried the following solution with the UITextArea and I expect this will work with UIButton as well.

First of all import this in your .m file -

#import <QuartzCore/QuartzCore.h>

and then in your loadView method add following lines

    yourButton.layer.cornerRadius = 10; // this value vary as per your desire
    yourButton.clipsToBounds = YES;

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 
    }

For Objective C:

submitButton.layer.cornerRadius = 5;
submitButton.clipsToBounds = YES;

For Swift:

submitButton.layer.cornerRadius = 5
submitButton.clipsToBounds = true

For iOS SWift 4

button.layer.cornerRadius = 25;
button.layer.masksToBounds = true;
