错误描述:
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.
在iOS9 beta中,苹果将原http协议改成了https协议,使用 TLS1.2 SSL加密请求数据。
解决方法:
在info.plist 加入key
<key>NSAppTransportSecurity</key><dict><key>NSAllowsArbitraryLoads</key><true/></dict>
