iOS 6 style sharing for Instagram.

Add the following files to your project

  • DMActivityInstagram.m
  • DMActivityInstagram.h

These are required so your app can create non-square images:

  • DMResizerViewController.h
  • DMResizerViewController.m
  • DMResizerViewController.xib

Make sure you add the apropriate variants of instagram.png for the devices you support, as well.

See DMAIDemoViewController in the example project for details of how to use this class. In short, thought:

DMActivityInstagram *instagramActivity = [[DMActivityInstagram alloc] init];

NSString *shareText = @"CatPaint #catpaint";
NSURL *shareURL = [NSURL URLWithString:@""];

NSArray *activityItems = @[self.imageView.image, shareText, shareURL];

UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:@[instagramActivity]];
[self presentViewController:activityController animated:YES completion:nil];

It's a bit more complex on iPad, as you need to use a UIPopoverController, but the gist is the same.

These classes are ARC enabled, but you can -fobjc-arc them to use in non-ARC projects.

Pull requests welcomed. If you use this, and want to give something back, consider purchasing some or all of my apps (for instance CatPaint and Iconizer). Obviously, envelopes full of cash are accepted as well.

Note: in the developer docs it says:

The default implementation of this method returns nil. Subclasses that provide additional UI using a view controller can override this method to return that view controller. If this method returns a valid object, the system presents the returned view controller for you, instead of calling the performActivity method. On iPad, your view controller is presented inside of a popover. On iPhone and iPod touch, your view controller is presented modally.

However experimental evidence shows otherwise. My iPad 2, running iOS 6 shows the returned DMResizerViewController as a modal view, not a popover. If anyone knows why this is, please advise.
