iOS 6 style photo sharing for VKontakte social network. It was initially developed for the PhotoSuerte app (there you might have a look on how it works) => http://photosuerte.com
The sample might be found here => TestViewController:
NSArray *items = @[[UIImage imageNamed:@"example.jpg"], @«Example», [NSURL URLWithString:@"https://www.youtube.com/watch?v=S59fDUZIuKY"]];
VKontakteActivity *vkontakteActivity = [[VKontakteActivity alloc] initWithParent:self];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc]
initWithActivityItems:items
applicationActivities:@[vkontakteActivity]];
[self presentViewController:activityViewController animated:YES completion:nil];
