Answer 1

Assuming this is your question:

//Why do I get empty arrays here e.g object 1 and 2 are returning empty ?

This code:

//Initiate arrays that hold data
object1 = [[NSMutableArray alloc] init];
object2 = [[NSMutableArray alloc] init];

Is creating new arrays dynamically on the heap. They are naturally empty because they were just brought into existence.

This line:

[getItems];

I think you are trying to call the getItems method you posted above, but you are not referencing an object in the method call. You want:

[self getItems];

And even then, you still have a problem; assuming the get part of the name is supposed to be getting something (items), you are not returning anything from the method (which is marked with a void return type).
