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

-今天早上更新到了Xcode7, 使用网络请求数据的时候,报错:
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.
-原因是:在iOS9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。
-解决方案:

在info.plist 加入key

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

-如图所示
