Ios 使用Whatsapp发送图像和文本

我需要从我的应用程序发送一个带有文本的图像，我知道如何只发送图像或文本，但我不知道如何将两者结合起来

只是一个图像：

    let image = UIImage(named: "Image") // replace that with your UIImage

    let filename = "myimage.wai"
    let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, false)[0] as! NSString
    let destinationPath = documentsPath.stringByAppendingString("/" + filename).stringByExpandingTildeInPath
    UIImagePNGRepresentation(image).writeToFile(destinationPath, atomically: false)
    let fileUrl = NSURL(fileURLWithPath: destinationPath)! as NSURL

    documentController = UIDocumentInteractionController(URL: fileUrl)
    documentController.delegate = self
    documentController.UTI = "net.whatsapp.image"
    documentController.presentOpenInMenuFromRect(CGRectZero, inView: self.view, animated: false)    

只是一段文字：

    var whatsappURL = NSURL(string: "whatsapp://send?text=hello,%20world")

    if UIApplication.sharedApplication().canOpenURL(whatsappURL!) {
        UIApplication.sharedApplication().openURL(whatsappURL!)
    }    

如何发送带有文本的图像

编辑#1

我发现了一个代码，它与whatsapp共享一个图像和文本，但它是用java编写的，你能把它翻译成swift吗

Intent whatsappIntent = new Intent(android.content.Intent.ACTION_SEND);
whatsappIntent.setType("image/*");
whatsappIntent.putExtra(Intent.EXTRA_TEXT, "Hello World");
whatsappIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + file)); //add image path
startActivity(Intent.createChooser(share, "Share image using"));
try {
    activity.startActivity(whatsappIntent);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(activity, "Whatsapp have not been installed.", Toast.LENGTH_SHORT).show();
}

您可以在WhatsApp上发布图像或文本。但是，您不能同时发布这两个内容，因为whatsapp不提供任何API，您可以添加标题并用文本发布图像

现在有一个api可用于与WhatsApp交互：

也可以找到以下有用的答案：

您可以使用UIDocumentInteractionController，如2014年8月4日对该问题的第二次回答中所述：

希望这会有所帮助。

swift 3的共享图像代码版本：

let image = myUIImageVariable
        let filename = "myimage.wai"
        let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, false)[0] as NSString
        var destinationPath = documentsPath.appending("/" + filename) as NSString
         destinationPath = destinationPath.expandingTildeInPath as NSString

        let fileUrl = NSURL(fileURLWithPath: destinationPath as String) as NSURL
        do{
            try UIImagePNGRepresentation(image!)?.write(to: fileUrl as URL, options: Data.WritingOptions.atomic)
        }
        catch {}
        let documentController = UIDocumentInteractionController(url: fileUrl as URL)
        documentController.delegate = self
        documentController.uti = "net.whatsapp.image"
        documentController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: false)

即使只是分享一张图片也似乎不起作用，但可能会节省一些人的时间

没有任何东西可以将文本和媒体共享结合到whatsapp上
