I have looked through several SO questions (e.g. this one, or this one) to find a way how to share image directly to WhatsApp. They all seem to follow the instructions from official documentation and so I ended up having this method:
extension WhatsAppInviter {
func shareImageViaWhatsapp(image: UIImage, onView: UIView) {
let urlWhats = "whatsapp://app"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) {
if let whatsappURL = URL(string: urlString) {
if UIApplication.shared.canOpenURL(whatsappURL as URL) {
guard let imageData = image.pngData() else { debugPrint("Cannot convert image to data!")
return }
let tempFile = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/image.wai")
do {
try imageData.write(to: tempFile, options: .atomic)
documentInteractionController = UIDocumentInteractionController(url: tempFile)
documentInteractionController?.uti = "net.whatsapp.image"
documentInteractionController?.presentOpenInMenu(from: CGRect.zero, in: onView, animated: true)
} catch {
UIAlertController.presentAlertWith(title: "Error", message: "There was an error while processing.", actions: [UIAlertAction(title: "OK", style: .default, handler: nil)])
return
}
} else {
UIAlertController.presentAlertWith(title: "Error", message: "Cannot open Whatsapp, make sure Whatsapp is installed on your device.", actions: [UIAlertAction(title: "OK", style: .default, handler: nil)])
}
}
}
}
}
The official documentation explicitly states:
Alternatively, if you want to show only WhatsApp in the application list (instead of WhatsApp plus any other public/*-conforming apps) you can specify a file of one of aforementioned types saved with the extension that is exclusive to WhatsApp:
images - «.wai» which is of type net.whatsapp.image
videos - «.wam» which is of type net.whatsapp.movie
audio files - «.waa» which is of type net.whatsapp.audio
When triggered, WhatsApp will immediately present the user with the contact/group picker screen. The media will be automatically sent to a selected contact/group.
However, when executing this code, I keep getting the document interaction controller as you can see here:
Am I doing something wrong or did something change with iOS 13? How can I skip this menu, or at least show only WhatsApp there?
