Swift开发笔记之UIButton基本用法

swift与OC有相同的UIButtonType

enum UIButtonType : Int {    case Custom    case System    case DetailDisclosure    case InfoLight    case InfoDark    case ContactAdd    static var RoundedRect: UIButtonType { get }}

代码实现部分ViewController.swift

import UIKitclass ViewController: UIViewController {    private var myButton : UIButton!    private var myInfoDarkButton: UIButton!    private var myInfoLightButton: UIButton!    private var myAddButton: UIButton!    private var myDetailButton: UIButton!    private var mySystemButton: UIButton!    override func viewDidLoad() {        super.viewDidLoad()        myButton = UIButton(frame: CGRectMake(0,0,200,50))        myButton.backgroundColor = UIColor.yellowColor()        myButton.layer.masksToBounds = true        myButton.layer.cornerRadius = 10        myButton.setTitle("无敌是多么寂寞", forState: UIControlState.Normal)        myButton.addTarget(self, action: "clickMyButton:", forControlEvents: UIControlEvents.TouchUpInside)        myButton.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)        myButton.center = CGPointMake(self.view.bounds.width/2, 200)        self.view.addSubview(myButton)        //设置button的类型        myInfoDarkButton = UIButton(type: UIButtonType.InfoDark)        myInfoLightButton = UIButton(type: UIButtonType.InfoLight)        myAddButton = UIButton(type: UIButtonType.ContactAdd)        myDetailButton = UIButton(type: UIButtonType.DetailDisclosure)        mySystemButton = UIButton(type: UIButtonType.System)        // mySystemButton        mySystemButton.frame = CGRectMake(0, 0, 200, 50)        // mySystemButton设定位置        mySystemButton.layer.position = CGPoint(x: self.view.frame.width/2, y:250)        // mySystemButton标题        mySystemButton.setTitle("mySystemButton", forState: UIControlState.Normal)        //myInfoDarkButton        myInfoDarkButton.frame = CGRectMake(0, 0, 200, 50);        myInfoDarkButton.layer.position = CGPoint(x: self.view.bounds.width/2, y: 300)        myInfoDarkButton.setTitle("myInfoDarkButton", forState: UIControlState.Normal)        // myInfoLightButton        myInfoLightButton.frame = CGRectMake(0, 0, 200, 50)        myInfoLightButton.layer.position = CGPoint(x: self.view.frame.width/2, y:350)        myInfoLightButton.setTitle("myInfoLightButton", forState: UIControlState.Normal)        // myAddButton        myAddButton.frame = CGRectMake(0, 0, 200, 50)        myAddButton.layer.position = CGPoint(x: self.view.frame.width/2, y:400)        myAddButton.setTitle("mySystemButton", forState: UIControlState.Normal)        // myDetailButton        myDetailButton.frame = CGRectMake(0, 0, 200, 50)        myDetailButton.layer.position = CGPoint(x: self.view.frame.width/2, y:450)        myDetailButton.setTitle("myDetailButton", forState: UIControlState.Normal)        self.view.addSubview(myInfoDarkButton)        self.view.addSubview(myInfoLightButton)        self.view.addSubview(myAddButton)        self.view.addSubview(myDetailButton)        self.view.addSubview(mySystemButton)        // Do any additional setup after loading the view, typically from a nib.    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }    internal func clickMyButton (sender:UIButton)    {        myButton.backgroundColor = UIColor.purpleColor()        myButton.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)        myButton.setTitle("无敌是多么空虚", forState: UIControlState.Normal)    }}
