Gesture recognizer

I'm not sure what I'm supposed to do beyond: 
```
- (void)pinchFired:(UIPinchGestureRecognizer *)recognizer {

    if (recognizer.state == UIGestureRecognizerStateBegan || recognizer.state == UIGestureRecognizerStateChanged) {
        [recognizer view].transform = CGAffineTransformScale([[recognizer view] transform], [recognizer scale], [recognizer scale]);
        [recognizer setScale:1];
    }
}
```
I previously had the following below before the closing bracket at the end of the method:
```
 if ([self.delegate respondsToSelector:@selector(floatingToolbar:didTryToZoom:)]) {
        [self.delegate floatingToolbar:self didTryToZoom:[recognizer view].transform];
    }
```
