App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. 解決

-今天早上更新到了Xcode7, 使用網絡請求數據的時候,報錯:
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.
-緣由是:在iOS9中，蘋果將原http協議改爲了https協議，使用 TLS1.2 SSL加密請求數據。
-解決方案:

在info.plist 加入key

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

-如圖所示
