create nsmutablearray dynamically

Question

Trying to create dynamic NSMutableArrays in a foor loop

//Here's my for loop
for (Object *object in parseMethod.objects) {

}

objects is an NSMutableArray which stores the objects; based on the number of the objects I'd like to create unique array, something like:

NSMutableArray *array1;
NSMutableArray *array2;
NSMutableArray *array3;
//and so on...
NSMutableArray *array[n];

Anyone can share an answer how to achieve this?

What about creating another one NSMutableArray that will store other NSMutableArray's? — Nekto

I'm not entirely sure I understood your problem, but I think you want to create a number of arrays, based on the number of objects in another array, right? If so, try this:

NSMutableArray *arrayWithOtherArraysInIt = [NSMutableArray arrayWithCapacity:[objectsClass count]];

for (objectClass *object in objectsClass.objects) {

   [arrayWithOtherArraysInIt addObject:[NSMutableArray arrayWithCapacity:0]];

}

Edit: Oh and by the way, you should think about your naming conventions. You're not supposed to use lowercase class names (like you did with objectClass). And I wouldn't name an object directly after its class' name...
