我如何在UILabel对齐文本?
UILabel
注意:根据UILabel类引用,从iOS 6开始,这种方法现在已弃用。
只需使用textAlignment属性就可以使用其中一个UITextAlignment值查看所需的对齐方式。(UITextAlignmentLeft, UITextAlignmentCenter或UITextAlignmentRight。)
textAlignment
UITextAlignment
UITextAlignmentLeft
UITextAlignmentCenter
UITextAlignmentRight
例如:[myUILabel setTextAlignment:UITextAlignmentCenter];
[myUILabel setTextAlignment:UITextAlignmentCenter];
更多信息请参见UILabel类引用。
下面是一个示例代码,展示如何使用UILabel对齐文本:
label = [[UILabel alloc] initWithFrame:CGRectMake(60, 30, 200, 12)]; label.textAlignment = NSTextAlignmentCenter;

从iOS 6及以后,UITextAlignment已弃用。使用NSTextAlignment
NSTextAlignment
myLabel.textAlignment = NSTextAlignmentCenter;
Swift版本来自iOS 6及更高版本
myLabel.textAlignment = .center
[lblTitle setTextAlignment:NSTextAlignmentCenter];
使用yourLabel.textAlignment = NSTextAlignmentCenter; for iOS >= 6.0和yourLabel.textAlignment = UITextAlignmentCenter; for iOS <6.0.
yourLabel.textAlignment = NSTextAlignmentCenter;
yourLabel.textAlignment = UITextAlignmentCenter;
Label.textAlignment = NSTextAlignmentCenter;
要在Swift的UILabel中居中文本(这是针对iOS 7+),你可以做:
myUILabel.textAlignment = .Center
或
myUILabel.textAlignment = NSTextAlignment.Center
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;
对于Swift 3,它是:
label.textAlignment = .center
在斯威夫特4.2和Xcode 10
let lbl = UILabel(frame: CGRect(x: 10, y: 50, width: 230, height: 21)) lbl.textAlignment = .center //For center alignment lbl.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..." lbl.textColor = .white lbl.backgroundColor = .lightGray//If required lbl.font = UIFont.systemFont(ofSize: 17) //To display multiple lines in label lbl.numberOfLines = 0 lbl.lineBreakMode = .byWordWrapping lbl.sizeToFit()//If required yourView.addSubview(lbl)
