Passing an object between view controllers, does the object become null in new controller?

Question

I am new to Objective C and trying to get my head around OOP in apps as opposed to web OOP.

Lets say I have a class theDay.h and theDay.m

setDay is a class which in one view controller it takes in a value, say a integer, via a set method, and then in another view controller using a get method you can get the value example: (if my syntax is wrong sorry, very new!)

[theDay setDay:1];

then to get it:

int day;
day = [theDay getDay];

Is this correct and is the object available throughout the views?

`setDay.h` and `setDay.m` are the same "class". Moreover, I think you want it to be a method (not a class). — cutsoy, May 03 '13 at 09:28

Yes the object will be available! You are passing reference to that object, not the object!! But you have to allocate that object somewhere in the code!
