ios - 如何在 xcode(swift) 和 phonegap 中将 iPhone 作为后台信标运行

Question

我设法创建了一个将手机变成信标发射器的应用程序。

它在 xcode (Swift) 和 phonegap 上运行良好。

我的下一步是让它在后台作为灯塔工作(我正在为 iOS 10 开发)。

我在网上发现了与此类似的问题，但它们都已过时，即旧的 ios、objective-C 和过时的插件

如果有人能为我提供一个工作示例或指导我如何更改 xcode s(wift) 和 phonegap 的代码，我将不胜感激

对于这两个代码，位置更新和后台获取都在目标的后台功能中检查。此外，两个播放列表都添加了隐私 - 位置始终使用说明

不幸的是，Apple 在 iOS 上阻止了作为信标在后台传输的能力。所有 CoreBluetooth 标准广告实际上都被阻止了，因为广告位是一种有限的资源，后台的多个应用程序会耗尽这个资源很快。

Apple 确实有一个专有的备份系统，用于在后台宣传蓝牙服务，该系统使用特殊的溢出区域来包含服务标识符。但是，虽然此方案适用于在后台宣传蓝牙服务，但它不适用于宣传信标，因为它破坏了格式。

底线:iOS 上的后台信标广告根本不起作用。对不起。
