当检测到Internet连接时如何在iOS应用程序上运行后台任务? [英] How to run a Background Task on iOS application when Internet connection is detected?
问题描述
我正在使用第三方库"Reachability.swift"
I'm using a third party library "Reachability.swift"
https://github.com/ashleymills/Reachability.swift
此博客文章使用Notification Center识别网络事件，因此可以在前台动态识别网络事件的变化
Followed this blog post to identify network event using Notification Center, So the change in network event can be identified dynamically in the foreground

我的要求:-
我需要运行一个使用 Alamofire (alamofire不需要的信息)的后台服务，以在Internet连接状态为活动"时将本地保存的SQLite数据推送到服务器上
I need to run a background service that uses Alamofire(Information not needed for alamofire) to push the locally saved SQLite data to the server whenever internet connection status is Active
重要说明:- iOS应用程序不应在前台运行，所有事情都应在后台运行
Important note:- iOS Application should not run in the foreground, everything should happen in the background

Please help me out to understand the topic, Thank in advance!
推荐答案
You should fully read and understand Apple's excellent documentation on background execution: Background Execution
只有少数几种应用程序类型可以在后台模式下永久运行:
There are only a few application types that are allowed to run permanently in background mode:
- 在后台播放可听内容的应用程序，例如音乐播放器应用程序
- 在后台录制音频内容的应用
- 始终使用户知道其位置的应用程序，例如导航应用程序
- 支持互联网协议语音(VoIP)的应用
- 需要定期下载和处理新内容的应用
- 从外部附件接收定期更新的应用
这些类型的应用必须请求特定的权限才能在后台运行.为您的应用声明错误的类型可能会导致Apple拒绝应用.
Apps of those types must ask for specific permission to run in the background. Declaring a wrong type for your app may lead to app rejection by Apple.
