How to round the corners of a button

You may want to check out my library called DCKit. It's written on the latest version of Swift.

You'd be able to make a rounded corner button/text field from the Interface builder directly:

It also has many other cool features, such as text fields with validation, controls with borders, dashed borders, circle and hairline views etc.

Pushing to the limits corner radius up to get a circle:

    self.btnFoldButton.layer.cornerRadius = self.btnFoldButton.frame.height/2.0;

If button frame is an square it does not matter frame.height or frame.width. Otherwise use the largest of both ones.

You can achieve by this RunTime Attributes

we can make custom button.just see screenshot attached.

kindly pay attention :

in runtime attributes to change color of border follow this instruction

1. create category class of CALayer

2. in h file

   @property(nonatomic, assign) UIColor* borderIBColor;
   

3. in m file:

   -(void)setBorderIBColor:(UIColor*)color {
       self.borderColor = color.CGColor;
   }
   
   -(UIColor*)borderIBColor {
       return [UIColor colorWithCGColor:self.borderColor];
   }
   

now onwards to set border color check screenshot

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;
