For the iPhone Apps, is it possible to have a Whatsapp link on products? Once link it would send a message to my mobile number through whatsapp. Please advice.

回答1:

You do it either of the method as tafh suggested which is custom method or as an iOS app developer I would suggest you to go with document interaction controller, initialize a UIDocumentInteractionController. These both with help you manage interactions. Check the link below for more information.

  (UIDocumentInteractionController *) setupControllerWithURL: (NSURL) fileURL
        usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {

    UIDocumentInteractionController *interactionController =
        [UIDocumentInteractionController interactionControllerWithURL: fileURL];
    interactionController.delegate = interactionDelegate;

    return interactionController;
}

notification = @"Your Daily Inspiration by the ";
notification = [notification stringByAppendingString:@"\n"];    
notification = [notification stringByAppendingString:textview.text];
NSString *whats=notification;
NSString *baseURL = [NSString stringWithFormat:@"whatsapp://send?text=%@",whats];
NSURL *url = [NSURL URLWithString:[baseURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

if ([[UIApplication sharedApplication] canOpenURL: url]) {
    [[UIApplication sharedApplication] openURL: url];
}
else
{
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry"
                                                        message:@"You can't send a thought on Whatsapp"
                                                       delegate:self
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
