我需要从我的应用程序发送带有文本的图像，我知道如何仅发送图像或仅发送文本，但我不知道如何将两者结合起来。
只是一张图片：
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？
EDIT #1
我找到了一个代码，可以将带有文本的图像共享到whatsapp，但它是用java编写的，你能将它翻译成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();
}
