Swift - NSURLSession下载在后台？ [英] Swift - NSURLSession downloading in background?

问题描述

我正在使用与$ code> AliExpress iOS应用程序相同的swift创建iOS应用程序。
这个应用程序有能力连接到我们的网站，并从JSON api在线下载所有的数据。
现在，我想从主页面的JSON api从我们的网站下载图标和横幅滑块的图片。但我不知道我能做什么我使用队列或背景功能，如在android中？另外，我是一个Android开发人员，我知道如何在Android中做到这一点。你也可以这样指导我。请引用我的示例代码或其逻辑描述。
