[Swift]UIKit学习之滑块控件UISwitch的用法

let mySwitch = UISwitch()
//设置位置（开关大小无法设置）
mySwitch.center = CGPointMake(100,50);
//设置默认值(开true/关false)
mySwitch.on = true;

self.view.addSubview(mySwitch);

//  ViewController.swift
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.

let mySwitch = UISwitch()
//设置位置（开关大小无法设置）
mySwitch.center = CGPointMake(100,50);
//设置默认值(开true/关false)
mySwitch.on = true;
mySwitch.addTarget(self, action: "switchDidChanged:",
forControlEvents:UIControlEvents.ValueChanged)

self.view.addSubview(mySwitch);
}

//
func switchDidChanged(sender:UISwitch){
if(sender.on){
self.view.backgroundColor = UIColor.brownColor()
myLabel.text = "开关已经打开";
myLabel.backgroundColor = UIColor.blueColor()

} else {
self.view.backgroundColor = UIColor.blackColor()
myLabel.text = "开关已经关闭"
myLabel.backgroundColor = UIColor.greenColor()
}
}
