要在Swift的UILabel中居中文本(这是针对iOS 7+)，你可以做:

myUILabel.textAlignment = .Center

Or

myUILabel.textAlignment = NSTextAlignment.Center

IO6.1 [lblTitle setTextAlignment NSTextAlignmentCenter):;

在xamarin ios 假设您的标签名称是title，然后执行以下操作

title.TextAlignment = UITextAlignment.Center;

从iOS 6及以后，UITextAlignment已弃用。使用NSTextAlignment

myLabel.textAlignment = NSTextAlignmentCenter;

Swift版本来自iOS 6及更高版本

myLabel.textAlignment = .center

Label.textAlignment = NSTextAlignmentCenter;

对于Swift 3，它是:

label.textAlignment = .center
