错误描述：
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.
在iOS9 beta中，苹果将原http协议改成了https协议，使用 TLS1.2 SSL加密请求数据。
解决方法：
在info.plist 加入key
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
iOS9 beta 请求出现App Transport Security has blocked a cleartext HTTP (http://)
