swift中UIButton的使用

let button = UIButton(type: UIButtonType.Custom)

// 添加到父视图，并设置frame
self.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 = false
button.enabled = true
button.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")
        }
}
