Share image/text through WhatsApp in an iOS app

Question

Is it possible to share images, text or whatever you want through Whatsapp in a iOS app? I'm searching on google but I only found results talking about Android implementations.

Answer 1

Is now possible in this way:

Send Text - Obj-C

NSString * msg = @"YOUR MSG"; NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg]; NSURL * whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {     [[UIApplication sharedApplication] openURL: whatsappURL]; } else {     // Cannot open whatsapp } 

Send Text - Swift

let msg = "YOUR MSG" let urlWhats = "whatsapp://send?text=\(msg)" if let urlString = urlWhats.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {     if let whatsappURL = NSURL(string: urlString) {         if UIApplication.sharedApplication().canOpenURL(whatsappURL) {             UIApplication.sharedApplication().openURL(whatsappURL)         } else {             // Cannot open whatsapp         }     } } 

Send Image - Obj-C

-- in .h file

<UIDocumentInteractionControllerDelegate>  @property (retain) UIDocumentInteractionController * documentInteractionController; 

-- in .m file

if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){      UIImage     * iconImage = [UIImage imageNamed:@"YOUR IMAGE"];     NSString    * savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];      [UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];      _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];     _documentInteractionController.UTI = @"net.whatsapp.image";     _documentInteractionController.delegate = self;      [_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];   } else {     UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];     [alert show]; } 

Send Image - Swift

let urlWhats = "whatsapp://app" if let urlString = urlWhats.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {     if let whatsappURL = NSURL(string: urlString) {          if UIApplication.sharedApplication().canOpenURL(whatsappURL) {              if let image = UIImage(named: "image") {                 if let imageData = UIImageJPEGRepresentation(image, 1.0) {                     let tempFile = NSURL(fileURLWithPath: NSHomeDirectory()).URLByAppendingPathComponent("Documents/whatsAppTmp.wai")                     do {                         try imageData.writeToURL(tempFile, options: .DataWritingAtomic)                         self.documentInteractionController = UIDocumentInteractionController(URL: tempFile)                         self.documentInteractionController.UTI = "net.whatsapp.image"                         self.documentInteractionController.presentOpenInMenuFromRect(CGRectZero, inView: self.view, animated: true)                     } catch {                         print(error)                     }                 }             }          } else {             // Cannot open whatsapp         }     } } 

Because a new security feature of iOS 9, you need add this lines on .plist file:

<key>LSApplicationQueriesSchemes</key>  <array>   <string>whatsapp</string>  </array>

I did not find a single solution for both. More information on http://www.whatsapp.com/faq/en/iphone/23559013
