How to create border in UIButton?

I use custom button in my app named "addButton" and I want to border it with white color how can i get the white color border around my custom button?

Solution

  • 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...
