In addition to the other answer(s), don't forget to set the masksToBoundsproperty.
除了其他答案之外，不要忘记设置masksToBounds属性。
#import <QuartzCore/QuartzCore.h>
label.layer.cornerRadius = 5.0;
label.layer.masksToBounds = YES;

Alternative if you're using the UI designer (Storyboard or nib file) you can set a User Defined Runtime Attribute.
或者，如果您使用 UI 设计器（故事板或 nib 文件），您可以设置用户定义的运行时属性。
Click on the view you want to have rounded corners, click Show the Identity Inspector (3rd tab, top right). Then click the + in User Defined Runtime Attributes and enter the following:
单击您想要圆角的视图，单击显示身份检查器（第三个选项卡，右上角）。然后单击 User Defined Runtime Attributes 中的 + 并输入以下内容：
Key Path: layer.cornerRadius
Type: Number
Value: whatever number, e.g. 5

It may be useful for you. Step1 :add the quartzcore framework to your project frameworks. In which file you want to write this code there, you have to use this.
它可能对你有用。步骤1：将quartzcore 框架添加到您的项目框架中。你想在哪个文件里写这段代码，你必须使用这个。
#import <QuartzCore/QuartzCore.h>
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 50, 30)];
myLabel.text = @"text";
myLabel.layer.cornerRadius =8.0;
[self.view addSubview:myLabel];
