objective c - iOS 7 round framed button

Question

the iOS App Store has a blue round framed button for buying/downloading apps.

In my App you can download additional content and I want to have a similar button, just because it looks familiar to the user.

If you don't know, what I mean: these buttons, like "$3.99"

How is this possible?

Answer 1

You can manipulate the CALayer of your button to do this pretty easily.

// assuming you have a UIButton or more generally a UIView called buyButton

buyButton.layer.cornerRadius = 2;
buyButton.layer.borderWidth = 1;
buyButton.layer.borderColor = [UIColor blueColor].CGColor;
// (note - may prefer to use the tintColor of the control)

you can tweak each of those to get the color and border effect you want.

You will also have to add an import in any file you want to use CALayers

#import <QuartzCore/QuartzCore.h>
