iOS 7圆框按钮 [英] iOS 7 round framed button

问题描述

iOS App Store有一个蓝色圆框按钮，用于购买/下载应用程式。

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

在我的应用程式中，您可以下载其他内容，

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

如果你不知道，我的意思是：这些按钮，例如$ 3.99

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

这是怎么回事？

推荐答案

您可以操作按钮的CALayer， >

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)

您还必须在要使用CALayers的任何文件中添加导入

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

#import <QuartzCore/QuartzCore.h>
