Ios – How to create border in UIButton

Best Answer

You can set the border properties on the CALayer by accessing the layer property of the button.

First, add Quartz

#import <QuartzCore/QuartzCore.h>

Set properties:

myButton.layer.borderWidth = 2.0f;
myButton.layer.borderColor = [UIColor greenColor].CGColor;

See:

https://developer.apple.com/documentation/quartzcore/calayer#//apple_ref/occ/cl/CALayer

The CALayer in the link above allows you to set other properties like corner radius, maskToBounds etc...
