Xcode7控件不显示&UIWebView不加载http请求

  • ViewController中控件不显示
  • 此处取消勾选Use Auto Layout并选择IPhone不然控件不会显示

  • 用UIWebView不能请求到Http： 
App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app‘s Info.plist file.
  • 因为苹果将原http协议改成了https协议，使用 TLS1.2 SSL加密请求数据。
  • 在info.plist 加入key 
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

示例： 

@IBOutlet weak var wv:UIWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        
        print("URL Loading....")
        
        
        wv.loadRequest(NSURLRequest(URL: NSURL(string:"http://www.rancho.site")!))
        
        print("URL loaded......")
    }

 

效果：
