title: Swift - add UIButton that is bigger than view it is being added to? Need Bigger selection area?
body: <p>Alright, so I have these image views that I move around using a good amount of code (this being my reason for not wanting to rework my whole script moving a UIButton that the image view is a subview of - it will screw up everything).</p>
  
  <p>They are little circles here:</p>
  
  <pre><code>bubble1.frame = CGRectMake(0, 0, screenSize.width*(21/330), screenSize.width*(21/330))
          bubble1.center = CGPointMake(lineView.bounds.width * 0.2, lineView.bounds.height * 0.98) //change when make smaller
          bubble1.layer.cornerRadius = bubble1.bounds.width * 0.5
          bubble1.backgroundColor = colorWithHexString(chosenColor)
          bubble1.userInteractionEnabled = false
          //bubble1.alpha = 0.0
  
          let bubbleBtn1 = UITapGestureRecognizer(target:self, action:#selector(HistoryViewController.bubble1Tap(_:)))
          bubble1.addGestureRecognizer(bubbleBtn1)
  </code></pre>
  
  <p>As you can see they have tapgesturerecognizers attached to them so when they are touched something is triggered. </p>
  
  <p>This works well except because the circles are so small (they need to be that small) it is hard to trigger the touch - I have looked around for ways to expand the area of the recognizer to no avail. </p>
  
  <p>I then tried to add a larger 70x70 button as a subview to my image view, and i know the larger button was added because I saw it as a larger square on top of my circle, except for some reason it only triggered its action WHERE the underlying <code>bubble1</code> was, rendering the button useless. </p>
  
  <p>How can I make the larger button trigger its action where the smaller image view is NOT? Ive looked at Qs like <a href="https://stackoverflow.com/questions/17249104/how-to-increase-selection-area-of-uibutton">How to increase selection area of UIButton?</a> but this is more geared to the issue tat my button does not work outside its superview's area. </p>
  
  <p>How can I solve this?</p>
