How to create a custom button

We can do this by setting properties of the UIButton for the states “normal” and “highlighted”. First we create pointers to the images, then we tell the button to use said images for each state:

If the button has transparency enabled use the “custom” setting in your Storyboard.
If the button should have a dynamic width to accommodate a changing text label you can use the following values:

UIImage *normal = [[UIImage imageNamed:@"greyoffbutton.png"]stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
