App Transport Security has blocked a cleartext HTTP (http://) resource load

今天开发中，遇到下问题，Xcode提示如下：

“App TransportSecurity has blocked a cleartext HTTP (http://) resource load since it isinsecure. Temporary exceptions can be configured via your app's Info.plistfile.”

简而言之：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。
如图所示：



成功解决。
