Question

我没有成功通过“UIDocumentInteractionController”分享任何东西，因为我几乎所有的教程和在线帮助都希望找到解决方案：

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whatsapp或messenger共享菜单的一个磁贴，没有任何反应，我有这个错误日志：

我在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，但没有帮助很多。

如果你有任何adea？谢谢，安托万。

Here is working code through that you can share your image to whatsapp, All you need to do is just add LSApplicationQueriesSchemes whatsapp into your plist file for WhatsApp sharing enable.

Swift 4

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")
    }
}
