# MCHelpGestureRecognizer ### A simple way to add help functionality into your app without the need for a button  To use, simply import `MCHelpGestureRecognizer.h` and `MCHelpGestureRecognizer.m` into your project (like any other `UIGestureRecognizer`). ```objective-c helpRecognizer = [[MCHelpGestureRecognizer alloc] initWithTarget:self action:@selector(showHelp)]; [helpRecognizer setDelegate:self]; [self.view addGestureRecognizer:helpRecognizer]; ``` And then add a callback method: ```objective-c -(void)showHelp { NSLog(@"HELP ME!"); } ``` Also, implement this delegate method to allow interaction with other UI Objects: ```objective-c - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { if ([touch.view isKindOfClass:[UIControl class]]) { return NO; } return YES; } ``` Simples! Oh, and yes, it's MIT licensed. Go wild!
