swift2.0 UIButton

概述var btn9:UIButton = UIButton(frame: CGRect(x: 50, y: 420, width: 100, height: 35))         btn9.backgroundColor = UIColor.whiteColor()         btn9.setTitle("边框按钮", forState: UIControlState.Normal)  

var btn9:UIbutton = UIbutton(frame: CGRect(x: 50,y: 420,wIDth: 100,height: 35))

btn9.backgroundcolor = UIcolor.whitecolor()

btn9.setTitle("边框按钮",forState: UIControlState.normal)

btn9.setTitlecolor(UIcolor.blackcolor(),forState: UIControlState.normal)

btn9.layer.bordercolor = UIcolor.blackcolor().CGcolor

btn9.layer.borderWIDth = 1
btn9.layer.cornerRadius = 5
给按钮添加图片：
btn3.setimage(UIImage(named: "btn1"),forState: UIControlState.normal)

添加点击事件

logout_bt.addTarget(self,action:"logoutAction",forControlEvents: .touchUpInsIDe)

写对应的方法

func logoutAction(){

print("退出账号")

}

shareBt.Alpha = 0.0//隐藏按钮

shareBt.enabled = false//让按钮不能点击
