使用Xcode7编写iOS9应用时，如果获取http://数据时会报如下错误：

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：
从iOS9起，新特性要求App访问网络请求，要采用 HTTPS 协议。

如果仍想要使用HTTP协议，解决办法如下：
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;
