Ionic IOS访问http受到限制

错误：

Application 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.    

解决方法：

手动在 ”项目名-Info.plist“第一个<dict>标签下添加下面标签

<key>NSAppTransportSecurity</key>

    <dict>

      <key>NSAllowsArbitraryLoads</key>

      <true/>

    </dict>
