自己用node.js 搭建APP服务器，然后用AFNetworking 请求 报如下错误：App TransportSecurity has blocked a cleartext HTTP (http://) resource load since it isinsecure. Temporary exceptions can be configured via your app's Info.

“App TransportSecurity has blocked a cleartext HTTP (http://) resource load since it isinsecure. Temporary exceptions can be configured via your app's Info.plistfile.”
原因：ATS禁止了HTTP的明文传输，因为它不安全。可以修改Info.plist文件，让它临时允许明文传输。
解决办法：
在Info.plist文件中添加"App Transport SecuritySettings", Type为"Dictionary",再添加"Allow Arbitray Loads", Type 为"Boolean"，“Value”为“YES”即可。
