XCODE / IOS - 直接打开分享音频文件到whatsapp

Question

我正在尝试将音频文件从我的 ios 应用程序共享到 whatsapp，但直接打开 whatsapp，而不是打开包含所有图块的共享菜单。

这是我现在拥有的：

// Getting the original file
let fileName = #MY FILE NAME#
let filePath = Bundle.main.path(forResource: fileName, ofType: "mp3")!
let urlData = URL.init(fileURLWithPath: filePath)
let nsData = NSData(contentsOf: urlData)

if (nsData != nil){

    // Creating the temporary file to share in the accessible ressources
    let newFileName = "file.mp3"
    let newFilePath = "\(NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])/\(newFileName)"
    nsData?.write(toFile: newFilePath, atomically: true)
    let newUrlData = URL.init(fileURLWithPath: newFilePath)

    // Sharing the file to whatsapp
    // Possibility 1 (does not work yet)
//    let documentController = UIDocumentInteractionController(url: newUrlData)
//    documentController.uti = "net.whatsapp.audio"
//    documentController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)

    // Possibility 2 (works only with the sharing menu)
    let activityVC = UIActivityViewController(activityItems: [NSURL(fileURLWithPath: newFilePath)], applicationActivities: nil)
    self.present(activityVC, animated: true, completion: nil)

}

当我这样做时，将音频文件共享到 whatsapp 是可行的，但它首先打开共享菜单，带有 Messenger 磁贴、消息磁贴、便笺磁贴...（它不适用于 Messenger应用程序）。最后，我希望能够在 Messenger 和 whatsapp 上分享。

As explicated here in the whatsapp documentation,我想分享文件的时候直接打开whatsapp应用程序:

Alternatively, if you want to show only WhatsApp in the application list (instead of WhatsApp plus any other public/*-conforming apps) you can specify a file of one of aforementioned types saved with the extension that is exclusive to WhatsApp:

images - «.wai» which is of type net.whatsapp.image

videos - «.wam» which is of type net.whatsapp.movie

audio files - «.waa» which is of type net.whatsapp.audio

When triggered, WhatsApp will immediately present the user with the contact/group picker screen. The media will be automatically sent to a selected contact/group.

所以我尝试更改行：

let newFileName = "file.mp3"

其中之一：

let newFileName = "file.mp3.waa"
let newFileName = "file.waa"
let newFileName = "file.waa.mp3"

但它仍然显示相同的共享菜单（并且无法读取以 .waa 扩展名结尾的音频文件）。

-> 1）是否可以做我想做的事？

-> 2) 如果没有，有没有一种方法可以使用相同的代码共享到 Messenger 和 whatsapp，同时保留一个共享菜单

-> 3) 如果不是，有没有办法根据不同的调用事件将共享菜单减少到只有一个图块，这样就不会混淆选择图块

谢谢，安托万

Answer 1

对照：

仅供参考：由于我对此进行了大量测试，我还找不到任何解决方案。

Whatsapp 识别文件扩展名，但甚至无法读取它。一旦分享，当你点击它时，它被写成“.whatsapp音频文件”，仅此而已（甚至没有直接分享）。

我给 whatsapp 开发团队发了一封电子邮件，他们说他们目前还有其他问题需要解决，所以这甚至不在他们的待办事项列表中。

拭目以待..
