ios - XCODE/IOS - 通过 UIDocumentInteractionController 共享

Question

我没有成功地通过“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 whatsapp 或 messenger 共享菜单的一个图 block 时，什么也没有发生，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。

Answer 1

这是工作代码，通过它您可以将图像分享到 whatsapp，您需要做的只是将 LSApplicationQueriesSchemes whatsapp 添加到您的 plist 文件中以启用 WhatsApp 共享。

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")
    }
}
