更改app使用http协议

新建程序网络访问报错

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

新特性要求App内访问的网络必须使用HTTPS协议
App Transport Security (ATS)

解决办法：

1. Info.plist中添加NSAppTransportSecurity类型为Dictionary

   

2. 在App Transport Security Setting下添加NSAllowsArbitraryLoads类型Boolean,值设为YES
