Just create an Aviary object:
AFPhotoEditorController *e = [[AFPhotoEditorController alloc] initWithImage:IMAGE];
[e setDelegate:self];
[self presentModalViewController:e animated:YES];
Then implement Finished & Canceled Delegate methods:
- (void)photoEditor:(AFPhotoEditorController *)editor finishedWithImage:(UIImage *)image
- (void)photoEditorCanceled:(AFPhotoEditorController *)editor
Good Luck!
