A UIActivity that launches the Sincerely postcard ordering process from a UIActivityViewController.

This has been tested on iPhones running iOS7. If you try it on a different device or iOS version, let me know how it works for you!

First, you need an Application Key from Sincerely. You can get an Application Key by going to http://dev.sincerely.com and requesting one. Follow their instructions for adding ShipLib to your project.

Next, download this project and drag the .h, .m, and .png files to your application.

Then, create an instance of PostcardUIActivity and add it to your UIActivityViewController before it is displayed:

PostcardUIActivity *postcardUIActivity = 
    [[PostcardUIActivity alloc] 
        initWithApplicationKey:@"YourApplicationKeyGoesHere"];    
UIActivityViewController *activityViewController = 
    [[UIActivityViewController alloc] initWithActivityItems:@[yourImage]
                                      applicationActivities:@[postcardUIActivity]];
[self presentViewController:activityViewController
                   animated:YES
                 completion:nil];

The PostcardUIActivity will support:

• UIImage objects
• NSURL objects that:
  • Are File URL's
  • End with ".jpg" or ".png"

If you pass the UIActivityViewController instances of NSURL's that point to image files on the device, the PostcardUIActivity will create UIImage objects from the files and pass the images to the Sincerely Controller.

So both of these objects could be passed to the UIActivityViewController and would be recognized as supported objects.

UIImage *image = [UIImage imageNamed@"SomeImage"];
NSURL *imageUrl = [NSURL fileURLWithPath:[NSHomeDirectory() stringByAppendingPathComponent:@"tmp/image.jpg"]
                             isDirectory:NO];
