share videos to whats app without showing ActionSheet

By Hường Hana 12:30 AM , , Leave a Comment

I need to share videos from my app to WhatsApp. I currently can do this by using an UIActivityViewController but the user experience is not good.

(The user presses a "send to WhatsApp" button and then has to select WhatsApp in the Action Sheet displayed by the UIActivityViewController).

I know it's possible to open the WhatsApp application and to share videos. For example, the application TuneMoji does it very well :

  • The user presses the "send to WhatsApp"
  • The WhatsApp application opens, asking for a destination user.

I'd like to do exactly the same.

Please, don't tell me to have a look at https://www.whatsapp.com/faq/en/iphone/23559013 , or to use a UIDocumentInteractionController : I want to avoid presenting an ActionSheet to the user.

Try this on the button action: 

func sendVideo(videoName: String, senderView: UIView) {         if UIApplication.sharedApplication().canOpenURL(NSURL(string: "whatsapp://app")!) {         let savePath: String = NSBundle.mainBundle().pathForResource(videoName, ofType: "mov")!        let documentInteractionController = UIDocumentInteractionController(URL: NSURL.fileURLWithPath(savePath))         documentInteractionController.UTI = "net.whatsapp.movie"         documentInteractionController.delegate = self         documentInteractionController.presentOpenInMenuFromRect(CGRectMake(0, 0, 0, 0), inView: senderView, animated: true)     }     else {          let alertController = UIAlertController(title: "Error occured", message: "WhatsApp is not installed on your device.", preferredStyle: .Alert)         let defaultAction = UIAlertAction(title: "OK", style: .Default, handler: nil)         alertController.addAction(defaultAction)         presentViewController(alertController, animated: true, completion: nil)     } }

Be sure to include WhatsApp URL scheme in your application's Info.plist under LSApplicationQueriesSchemes key if you want to query presence of WhatsApp on user's iPhone using 'canOpenURL'

You can open whatsapp like this.

NSURL *urlOfWhatsApp = [NSURL URLWithString:@"whatsapp://"];  if ([[UIApplication sharedApplication] canOpenURL:urlOfWhatsApp]) { //check app can open whatsapp or not.      [[UIApplication sharedApplication] openURL:urlOfWhatsApp];  } else {     NSLog(@"You device do not have whatsapp."); }

You can send text messages using WhatsApp URL Scheme like this:

NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?text=Hello%2C%20World!"]; if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {     [[UIApplication sharedApplication] openURL: whatsappURL]; }

This will open the application and ask for destination to send Hello World!.

To send images or videos, you can use the UIActivityViewController like you already noticed, or use UIDocumentInteractionController, that may be closer to what you are looking for:

_documentController = [UIDocumentInteractionController interactionControllerWithURL:_imageFileURL]; _documentController.delegate = self; _documentController.UTI = @"net.whatsapp.image"; [_documentController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];

To show only whatsapp in the application list, use the private whatsapp file extension or UTI:

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.
