如何在UILabel周围绘制边框？ [英] How to draw border around a UILabel?

问题描述

UILabel有没有办法在自己周围画一个边框？

Is there a way for UILabel to draw a border around itself? This is useful for me to debug the text placement and to see the placement and how big the label actually is.

推荐答案

这可以帮助我调试文本展示位置和查看展示位置以及标签的实际大小。通过其底层CALayer属性设置标签的边框：

You can set label's border via its underlying CALayer property:

#import <QuartzCore/QuartzCore.h>

myLabel.layer.borderColor = [UIColor greenColor].CGColor;
myLabel.layer.borderWidth = 3.0;
