MCTweetbotActivity is a UIActivity subclass that provides an "Open In Tweetbot" action to a UIActivityViewController.

• iOS 6.0 or greater

Add the MCTweetbotActivity.m, MCTweetbotActivity.h and MCTweetbotActivityMedia.xcassets files to your project.

Simply create an instance of MCTweetbotActivity and pass that object into the applicationActivities array when creating a UIActivityViewController.

NSURL *URL = [NSURL URLWithString:@"http://google.com"];
MCTweetbotActivity *tweetbot = [MCTweetbotActivity new];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[URL] applicationActivities:@[tweetbot]];

Note that you can include the activity in any UIActivityViewController and it will only be shown to the user if there is a NSURL or NSString in the activity items.
