One little thing is puzzling me about creating an object from your own class. What is the difference between:

myClass *myObject;

and

myClass *myObject=[[myClass alloc] init];

Im a noob too so here is my view (right or wrong!)

The first example if simply a variable declaration of an object type. i.e. it has not been instatiated yet.

The second is the same but the extra bit assigns the variable (myObject) to a new instance of type myClass. So [myClass alloc] allocates the memory for the object and init is a method call on myClass to initialise it.


Hope that makes sense (and is correct :) )
