Answer 1

UIButton* closeBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 50, 90, 35)];
//Customise this button as you wish then
closeBtn.layer.cornerRadius = 10;
closeBtn.layer.masksToBounds = YES;//Important

Answer 2

updated for Swift 3 :

used below code to make UIButton corner round:

 yourButtonOutletName.layer.cornerRadius = 0.3 *
        yourButtonOutletName.frame.size.height

Answer 3

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

thanks

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.

Answer 5

Import QuartCore framework if it is not there in your existing project, then import #import <QuartzCore/QuartzCore.h> in viewcontroller.m

UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect]];
CGRect frame = CGRectMake(x, y, width, height); // set values as per your requirement
button.layer.cornerRadius = 10;
button.clipsToBounds = YES;

Answer 6

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.
