XCODE / IOS - 通过 UIDocumentInteractionController 共享

Question

我没有成功通过“UIDocumentInteractionController”分享任何东西，因为我浏览了几乎所有的教程和在线帮助我希望找到一个解决方案：

这是我使用的代码：

    let fileName = "banner_1"
    let filePath = Bundle.main.path(forResource: fileName, ofType: "jpg")!
    let urlData = URL.init(fileURLWithPath: filePath)
    let nsData = NSData(contentsOf: urlData)

    let newFileName = "banner_1.jpg"
    let newFilePath = "\(NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])/\(newFileName)"
    nsData?.write(toFile: newFilePath, atomically: true)
    let newUrlData = URL.init(fileURLWithPath: newFilePath)

    documentController?.url = urlData // or newUrlData
    documentController?.uti = "net.whatsapp.image"
    documentController?.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)

每次我按下 whatsapp 或 messenger 的共享菜单的一个图块时，什么都没有发生，并且我有这个错误日志：

我确实在 plist 文件中添加了“LSApplicationQueriesSchemes”和“whatsapp”。

我尝试使用 UIDocumentInteractionControllerDelegate 来查找是否有任何奇怪的事件，但没有太大帮助。

如果你有任何想法？！ 谢谢，安托万。

这是工作代码，您可以通过它将图像共享到whatsapp，您只需将LSApplicationQueriesSchemes whatsapp添加到您的plist文件中即可启用WhatsApp共享。

func shareOnWhatsUp() {

    if UIApplication.shared.canOpenURL(URL(string: "whatsapp://app")!) {
        var documentInteractionController: UIDocumentInteractionController = UIDocumentInteractionController.init()
        let iconImage = UIImage(named: "IMG_1.jpg")
        let pathURL =   URL.init(fileURLWithPath: NSHomeDirectory() + "/Documents/whatsAppTmp.wai")

        do {
            try UIImageJPEGRepresentation(iconImage!, 1.0)?.write(to: pathURL)
        } catch {
            print(error.localizedDescription)
        }
        documentInteractionController!.url = pathURL
        documentInteractionController!.uti = "net.whatsapp.image"
        documentInteractionController!.delegate = self
        documentInteractionController!.presentOpenInMenu(from: CGRect(x: 0, y: 0, width: 0, height: 0), in: self.view, animated: true)
    }
    else {
        print("whatsup not installed")
    }
}
