In Swift :-
在斯威夫特：-
yourLabelName.textAlignment = .center
Here .centeris NSTextAlignment.center
这.center是NSTextAlignment.center

Here you are,
这个给你，
yourLabel.textAlignment = UITextAlignmentCenter
EDIT
编辑
if you target above iOS6 use NSTextAlignmentCenteras UITextAlignmentCenteris depreciated
如果你的目标上面iOS6的使用NSTextAlignmentCenter作为UITextAlignmentCenter折旧
Hope it helps.
希望能帮助到你。

This has changed as of iOS 6.0, UITextAlignment has been deprecated. The correct way to do this now is:
从 iOS 6.0 开始，这已经改变了，UITextAlignment 已被弃用。现在执行此操作的正确方法是：
yourLabel.textAlignment = NSTextAlignmentCenter;
Here is the NSTextAlignment enumerable that gives the options for text alignment:
这是 NSTextAlignment 枚举，它提供了文本对齐的选项：
Objective-C:
目标-C：
enum {
NSTextAlignmentLeft = 0,
NSTextAlignmentCenter = 1,
NSTextAlignmentRight = 2,
NSTextAlignmentJustified = 3,
NSTextAlignmentNatural = 4,
};
typedef NSInteger NSTextAlignment;
Swift:
迅速：
enum NSTextAlignment : Int {
case Left
case Center
case Right
case Justified
case Natural
}

If you have a multiline UILabel you should use a NSMutableParagraphStyle
如果你有一个多行 UILabel 你应该使用 NSMutableParagraphStyle
yourLabelName.numberOfLines = 0
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .Center
let attributes : [String : AnyObject] = [NSFontAttributeName : UIFont(name: "HelveticaNeue", size: 15)!, NSParagraphStyleAttributeName: paragraphStyle]
let attributedText = NSAttributedString.init(string: subTitleText, attributes: attributes)
yourLabelName.attributedText = attributedText

In Swift 3 and beyond it should be
在斯威夫特3和超越它应该是
yourlabel.textAlignment = NSTextAlignment.center

in swift 4:
快速 4：
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.center
// in Swift 4.2
let attributedString = NSMutableAttributedString(string: "Your String", attributes:[NSAttributedString.Key.paragraphStyle:paragraphStyle])
// in Swift 4.1--
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedStringKey.paragraphStyle:paragraphStyle])
let yourLabel = UILabel()
yourLabel.attributedText = attributedString
