swift中UIButton的使用

概述let button = UIButton(type: UIButtonType.Custom) // 添加到父视图，并设置frameself.view.addSubview(button)button.frame = CGRectMake(10.0, 10.0, 200.0, 40.0) // 背景属性设置button.backgroundColor = UIColor.yellowCol

let button = UIbutton(type: UIbuttonType.Custom)

// 添加到父视图，并设置frameself.vIEw.addSubvIEw(button)button.frame = CGRectMake(10.0,10.0,200.0,40.0)

// 背景属性设置button.backgroundcolor = UIcolor.yellowcolor()// button.setBackgroundImage(UIImage(named: "normalimage"),forState: UIControlState.normal)// button.setBackgroundImage(UIImage(named: "hightimage"),forState: UIControlState.Highlighted)

// 图标设置button.setimage(UIImage(named: "normalimage"),forState: UIControlState.normal)button.setimage(UIImage(named: "hightimage"),forState: UIControlState.Highlighted)button.imageEdgeInsets = UIEdgeInsetsMake(0.0,-50.0,0.0,0.0)

// 标题设置button.setTitle("button",forState: UIControlState.normal)button.setTitlecolor(UIcolor.blackcolor(),forState: UIControlState.normal)button.setTitlecolor(UIcolor.redcolor(),forState: UIControlState.Highlighted)button.setTitleShadowcolor(UIcolor.greencolor(),forState: UIControlState.normal)button.TitleLabel?.Font = UIFont(name: "GillSans",size: 20.0)button.TitleEdgeInsets = UIEdgeInsetsMake(0.0,-50.0)

button.selected = falsebutton.enabled = truebutton.userInteractionEnabled = true

// 响应事件button.addTarget(self,action: Selector("buttonClick:"),forControlEvents: UIControlEvents.touchUpInsIDe)

// 响应事件func buttonClick(button:UIbutton) -> VoID{        button.selected = !button.selected        if button.selected == true        {            print("选中按钮")                        let buttonTitle = button.TitleLabel?.text            print(buttonTitle)        }        else        {            print("未选中按钮")        }}
