title: iPhone - How to partially hide the subview?
body: <p>I am developing one sample application using gestures, where i can pinch, pan and rotate. I have one main image view width and height is 300 and origin x is 0 and y is 70. This imageview I am using from interface builder. After this i am adding one label programmatically on the middle of the imageView. After adding the label I can able to pan, pinch and rotate the label on the view. Now the actual requirement is when i drag the label outside the imageview I should be display the  partial label, for example (My label text is ABCDXYZ). As soon as I drag the Z outside the Z should be invisible, other part ABCDXY should be visible. More clear is drag the one view inside other view. How can i achieve this.  </p>
