DMActivityInstagram

iOS 6 style sharing for Instagram.

The easiest way to integrate DMActivityInstagram is via CocoaPods.

pod 'DMActivityInstagram', :git => 'https://github.com/coryalder/DMActivityInstagram.git'

If you're still living in the pre-CocoaPods stone age like a neanderthal, add the following files to your project

  • DMActivityInstagram.m
  • DMActivityInstagram.h
  • DMResizerViewController.h
  • DMResizerViewController.m
  • DMResizerViewController.xib
  • instagram.png
  • [email protected]
  • `instagram~ipad.png
  • [email protected]

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

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

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

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. Again, see the example for usage.

These classes are ARC enabled, but you can -fobjc-arc them to use in non-ARC projects (not required if you're using CocoaPods).

If your iPad app creates square images, you need to set UIActivityInstagram's presentFromButton property. This should be the UIBarButtonItem you are presenting the UIActivityViewController from. This property is overwritten if the image is not square, and the UIDocumentInteractionController is shown from within the resizer view instead.

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.

A side note about the implementation

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.
