title: Add UITapGestureRecognizer to UITextView without blocking textView touches
body: <p>How can I add a <code>UITapGestureRecognizer</code> to a UITextView but still have the touches getting through to the <code>UITextView</code> as <em>normal</em>?</p>
  
  <p>Currently as soon as I add a custom gesture to my textView it blocks the tap for UITextView default actions like positioning the cursor.</p>
  
  <pre><code>var tapTerm:UITapGestureRecognizer = UITapGestureRecognizer()
  
  override func viewDidLoad() {
      tapTerm = UITapGestureRecognizer(target: self, action: "tapTextView:")
      textView.addGestureRecognizer(tapTerm)
  }
  
  func tapTextView(sender:UITapGestureRecognizer) {
      println("tapped term – but blocking the tap for textView :-/")
  …
  }
  </code></pre>
  
  <p>How can I process taps but keep any textView behaviour like cursor positioning as is?</p>
