swift学习之Label

//UILabel的使用方法
let label:UILabel = UILabel(frame: CGRect(x: 0, y: 100, width: view.frame.size.width, height: 100))

label.text = "人人都爱萌叔老,天天不吃药"

label.textAlignment = NSTextAlignment.Center
// label.numberOfLines = 2
//设置文字过长的显示模式
label.lineBreakMode = NSLineBreakMode.ByTruncatingMiddle

//根据文本框范文自动缩放字体,以达到完全显示的目的
label.adjustsFontSizeToFitWidth = true

//字体大小 粗体

// label.font = UIFont.boldSystemFontOfSize(14)
//正常
label.font = UIFont.systemFontOfSize(14)

label.textColor = UIColor.blueColor()

//设置阴影
label.shadowColor = UIColor.cyanColor()

label.shadowOffset = CGSizeMake(1.0, 1.0)

//将文本标签加入视图中
view.addSubview(label)

// 给label添加点击事件
label.userInteractionEnabled = true

let tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "tap:")

label.addGestureRecognizer(tap)

}

func tap(tap : UITapGestureRecognizer){

print("tihis is click")
}
