title: tap gesture recognizer - which object was tapped?
body: <p>I'm new to gesture recognizers so maybe this question sounds silly: I'm assigning tap gesture recognizers to a bunch of UIViews. In the method is it possible to find out which of them was tapped somehow or do I need to find it out using the point that was tapped on screen?</p>
  
  <pre><code>for (NSUInteger i=0; i&lt;42; i++) {
          float xMultiplier=(i)%6;
          float yMultiplier= (i)/6;
          float xPos=xMultiplier*imageWidth;
          float yPos=1+UA_TOP_WHITE+UA_TOP_BAR_HEIGHT+yMultiplier*imageHeight;
          UIView *greyRect=[[UIView alloc]initWithFrame:CGRectMake(xPos, yPos, imageWidth, imageHeight)];
          [greyRect setBackgroundColor:UA_NAV_CTRL_COLOR];
  
          greyRect.layer.borderColor=[UA_NAV_BAR_COLOR CGColor];
          greyRect.layer.borderWidth=1.0f;
          greyRect.userInteractionEnabled=YES;
          [greyGridArray addObject:greyRect];
          [self.view addSubview:greyRect];
          NSLog(@"greyGrid: %i: %@", i, greyRect);
  
          //make them touchable
          UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter)];
          letterTapRecognizer.numberOfTapsRequired = 1;
          [greyRect addGestureRecognizer:letterTapRecognizer];
      }
