我在检查员看到我可以改变背景颜色，但我也想改变边框的颜色和厚度，这是可能吗？

I saw in the inspector that I can change the background color, but I'd like to also change the border color and thickness, is this possible?

推荐答案

您需要使用视图的图层来设置边框属性。例如：

You need to use view's layer to set border property. e.g:

#import <QuartzCore/QuartzCore.h>
...
view.layer.borderColor = [UIColor redColor].CGColor;
view.layer.borderWidth = 3.0f;

您还需要链接到QuartzCore.framework才能访问此功能。

You also need to link with QuartzCore.framework to access this functionality.
