CATiledLayer : Sample code

I need to load the higher resolution image in UIImageView. After going through approaches seems like,If we load higher resolution images memory usage goes huge [ width * height * 4 ] So to overcome this, need to implement CATiledLayer to support higher ones. Referred PhotoScroller app,but they are using images from resource and I need to pick those images from Photo library.

Can anyone help me on this,how to implement this algorithm. any links or ref will be appriciated.

Thanks,

Sagar
