Learning Objective-C

I am struggling here learning objective-c for programming with cocoa! You see I came from a procedural type language, PHP. Yes PHP can be considered quite a newbie language however without it most of my sites would simply not have been built. Now going to objective-c i am finding it hard because it is obviously based on objects. I have only written a couple of objects in PHP, and even they were not so crash hot. So coming straight into objective-c and not even knowing c is pretty hardcore. Maybe i will write some tutorials on here, because i am finding the resources out there to be a little weak!
