我在视图中使用了一些标签。我想在我的 iphone 应用程序中制作圆角标签。我使用以下代码来做到这一点，但它不起作用。我在使用该属性时遇到了一些错误。
label.layer.borderColor = [UIColor blueColor].CGColor;
label.layer.borderWidth = 4.0;
label.layer.cornerRadius = 8;

Hard to know for sure what you're asking as you didn't include the errors you're getting. Have you added the QuartzCoreframework to your project and #import <QuartzCore/CALayer.h>to the file modifying the layer? If that's not it, add the errors and more info to your question.
很难确定你在问什么，因为你没有包括你得到的错误。您是否将QuartzCore框架添加到您的项目和#import <QuartzCore/CALayer.h>修改图层的文件中？如果不是这样，请将错误和更多信息添加到您的问题中。
EDIT: you can also #import <QuartzCore/QuartzCore.h>as suggested in the comments. QuartzCore.hincludes CALayer.halong with the rest of the QuartzCorecomponents.
编辑：您也可以#import <QuartzCore/QuartzCore.h>按照评论中的建议。QuartzCore.h包括CALayer.h与其余QuartzCore组件一起。

I was facing the same problem, using a UILabel with backgroundColor in a cell, and added this to work correctly :
我遇到了同样的问题，在单元格中使用带有 backgroundColor 的 UILabel，并添加了它以正常工作：
label.layer.cornerRadius=8.0;
label.clipsToBounds=YES;

Just add #import <QuartzCore/QuartzCore.h>in your .m file
只需添加#import <QuartzCore/QuartzCore.h>您的 .m 文件
and suppose you have a UILabel *myLabel;
假设你有一个 UILabel *myLabel;
just do [myLabel.layer setCornerRadius:20];//value '20' can be changed according to your wish :)
只是做[myLabel.layer setCornerRadius:20];//值'20'可以根据你的意愿改变:)

This simple code enough for RoundLabel
这个简单的代码对于RoundLabel 来说已经足够了
LabelName.layer.cornerRadius = LableName.frame.size.height/2;
LabelName.layer.masksToBounds = YES;

I would create a view with rounded corners and add the label to that view.
我会创建一个带圆角的视图并将标签添加到该视图。
