}

 

注：

在调接口时，碰到以下异常，是因为xcode中info.plist文件中没有设置限制https请求。

 

 

解决方法：

在Info.plist中添加NSAppTransportSecurity类型Dictionary。 

在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES

    <key>NSAppTransportSecurity</key>

    <dict>

          <key>NSAllowsArbitraryLoads</key>

          <true/>

    </dict>
