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。

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 as NSString).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。

自适应是按照view的大小等比例拉伸的 不同屏幕大小可能会被影响。你要根据你的需求计算这个相对距离来做自适应
