How to round the corners of a button

For iOS SWift 4

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

First set width=100 and Height=100 of button

> Objective C Solution

YourBtn1.layer.cornerRadius=YourBtn1.Frame.size.width/2;
YourBtn1.layer.borderColor=[uicolor blackColor].CGColor;
YourBtn1.layer.borderWidth=1.0f;

> Swift 4 Solution

YourBtn1.layer.cornerRadius = YourBtn1.Frame.size.width/2
YourBtn1.layer.borderColor = UIColor.black.cgColor
YourBtn1.layer.borderWidth = 1.0

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()

For **Objective C**:

```
submitButton.layer.cornerRadius = 5;
submitButton.clipsToBounds = YES;
```
For **Swift**:
```
submitButton.layer.cornerRadius = 5
submitButton.clipsToBounds = true
```

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;

You can use outlet connection and didSet function for your button on the view;

@IBOutlet weak var button: UIButton!{
didSet {
button.layer.cornerRadius = 5;
button.layer.masksToBounds = true;
}
}

# 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
}
```
