here is a general way to create an id variable.

id someVariable = value;

you dont have to use * since id variables are pointers by default, you dont have to explicitly declare them as pointers since they already are.

and the syntax for creating NSNumber literals looks like this: @X where x is the number you want to make. so you can use @4 to create an NSNumber with the value of 4
