iOS xcode 网络请求报错：The resource could not be loaded because the App Transport Security policy requires

今天用了一下UIWebView控件，loadRequest后报错：

The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.

Google后查证，iOS9引入了新特性App Transport Security (ATS)。详情：App Transport Security (ATS)

新特性要求App内访问的网络必须使用HTTPS协议。

 最终找到以下解决办法：

1. 在Info.plist中添加NSAppTransportSecurity类型Dictionary。
2. 在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES
