Finger Gesture in TabBar
<p>I have to create a Tab bar. If I do a single tap on the tab bar, the label should read some quote.</p>

<p>Similarly it should recognize these touch gestures and display the text in the label :</p>

<p>1) double tap </p>

<p>2) 1 finger : top to bottom swipe.</p>

<p>How can I do this? </p>
