我需要用 c# 开发一个应用程序,它可以在连接到系统时自动检测 iPhone 并读取 iPhone 文件系统的特定文件。我基本上希望这个文件自动从设备下载到 PC。我使用了 USBpcap 工具,该工具建议 iTunes 使用某种 XML 格式连接到手机。非常感谢任何帮助或见解。是否有任何第三方 API 文档可以帮助我入门?有一些应用程序可以复制 iTunes 功能,例如Copytrans
Apple 是否提供任何协议或 API?
我一直在挖掘互联网,发现这个链接Layered communication for iPhone。此外,我正在使用 LibUsbDotNet 库与 USB 设备进行通信(示例)。任何人都可以建议应该使用哪些端点。
在我看来,我必须在 Windows 应用程序中实现 usbmuxd。它是一个多层协议。一定有一些库实现了usbmuxd(我不认为我必须自己实现协议)
我对 iTunes 通信和 USB 通信不太了解。我正在尽可能多地添加信息(当然还有我在研发中提出的东西)。非常感谢任何帮助。

我一直在尝试向 iPhone 发送 hello 数据包字节,但我无法从手机读取任何响应。
