ActionScript 3 mask in Objective - C
===

In **ActionScript 3** we can apply masking of two objects like this:<br>

    mc.mask = maskMC; 

where **mc** and **maskMC** are two objects (MovieClips). It is so simple!<br><br>

But, how to achieve similar result in Objective - C? Assume I have two UIImageView, I want something like: 

    imageView1.mask = imageView2; //Off course, this is not objective - c ;)
