本月初，苹果宣布swift编程语言开源，最近苹果软件工程高级副总裁 Craig Federighi 又坦言，Swift将深度整合到iCloud 和 OS X 中，这意味着swift将成为今后iOS开发的主流语言，从事iOS开发，swift是必学语言。

看到苹果近期的消息有点鸡冻，废话不多说，今天要和大家分享的是在网上看到的关于使用swift语言纯代码实现iphone软件自适应屏幕的源码，一起来看看吧。

// ViewController.swift

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var wb: UIWebView!

@IBOutlet weak var bn_blue: UIButton!

@IBOutlet weak var bn_org: UIButton!

@IBOutlet weak var lb_msg: UILabel!

//var webView : UIWebView?

override func viewDidLoad() {

super.viewDidLoad()

// Do any additional setup after loading the view, typically from a nib.

lb_msg.text = self.view.bounds.width.description

var width = self.view.bounds.width.description

var height = self.view.bounds.height.description

var fwidth = (width asNSString).floatValue

var fheight = (height as NSString).floatValue//屏幕高度

let sizew:CGFloat = CGFloat(fwidth/2)

let posy:CGFloat = CGFloat(fheight-40)

let sizewebview:CGFloat = CGFloat(fwidth)

let posywebview:CGFloat =CGFloat(fheight-60)

let registerBtn : UIButton = UIButton()

registerBtn.frame = CGRectMake(0, posy, sizew, 40)

registerBtn.backgroundColor = UIColor.orangeColor()

registerBtn.setTitle("注册", forState: UIControlState.Normal)

registerBtn.addTarget(self, action: "goList:",forControlEvents:UIControlEvents.TouchUpInside)

self.view.addSubview(registerBtn)

let registerBtn2 : UIButton = UIButton()

registerBtn2.frame = CGRectMake(sizew, posy, sizew, 40)

registerBtn2.backgroundColor = UIColor.blueColor()

registerBtn2.setTitle("登陆", forState: UIControlState.Normal)

registerBtn2.addTarget(self, action: "goList:",forControlEvents:UIControlEvents.TouchUpInside)

self.view.addSubview(registerBtn2)

var webView = UIWebView()

var url = NSURL(string:"http://www.baidu.com")

var urlRequest = NSURLRequest(URL:url!)

webView.frame = CGRectMake(0, 20, sizewebview, posywebview)

webView.loadRequest(urlRequest)

self.view.addSubview(webView)

}

@IBAction func goList(sender: AnyObject) {

var rootVC :ListViewController = ListViewController(nibName:"ListViewController", bundle: nil)

let NVC :UINavigationController =UINavigationController(rootViewController: rootVC)

NVC.setNavigationBarHidden(true, animated: true)

self.presentViewController(NVC, animated: true, completion: nil)

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.

}

自适应屏幕源码分享到此，强烈建议大家可以自己动手跑一下上述代码。
