iOS iOS9 beta 請求出現App Transport Security has blocked a cleartext HTTP (http://)

錯誤描述：

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，蘋果將原http協議改成了https協議，使用 TLS1.2 SSL加密請求數據。

解決方法：

在info.plist 加入key

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
