【iOS开发问题】App Transport Security has blocked a cleartext HTTP (http://) resource load

问题：

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 Xcode7后的iOS9 http协议修改为https协议。

解决方案：info.plist文件中加入

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

运行成功。
