When Called From UIActivityViewController WhatsApp Freezes After a Recipient Is Selected

Question

I am using UIActivityViewController to share my iOS app.

When WhatsApp is selected from the list of options, it takes me to the proper screen. I can move around, and all the buttons work.

However, once I select a recipient, WhatsApp freezes.

Does anyone know what's going on here? Has anyone encountered this bug before?

EDIT (Code Added)

Here's the code I'm using to call the UIActivityViewController:

- (void) sharePressed:(UIBarButtonItem *)sender {

NSString* shareText = @"Hello World!";

UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:@[shareText] applicationActivities:nil];

[self presentViewController:controller animated:YES completion:nil];


NSLog(@"This method ran: sharePressed");
}

It's as basic as it gets. It works for everything except WhatsApp.

Answer 1

try this code

- (IBAction)shareButton:(UIBarButtonItem *)sender
{
    NSString *textToShare = @"Look at this awesome website for aspiring iOS Developers!";
    NSURL *myWebsite = [NSURL URLWithString:@"http://www.codingexplorer.com/"];

    NSArray *objectsToShare = @[textToShare, myWebsite];

    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

    NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                   UIActivityTypePrint,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr,
                                   UIActivityTypePostToVimeo];

    activityVC.excludedActivityTypes = excludeActivities;

    [self presentViewController:activityVC animated:YES completion:nil];
}

Answer 2

I think the error was actually an internal problem with either whatsapp or UIActivityViewController because my other apps that use UIActivityViewController couldn't share on whatsApp last night. This morning though, even though I didn't change anything in my code, everything works perfectly!

Answer 3

I think is a bug in WhatsApp after yesterday update.

Update: You can send an NSUrl instead of NSString.
