I missed the first part of this post so I'm probably speaking foolishly...
but.
2 things.
if the arrays in the main array are not mutatable then you must build a
new array and replace the one you other wise want to edit. (how many
times can we say array in a sentence)
NSArray * theNewlyEditedArray = [NSArray
arrayWithObjects:anObject,anotherObject,etc,nil];
//here you have to rebuild your array kind of from scratch.
[mainArray replaceObjectAtIndex:index withObject:theNewlyEditedArray];
I have used this and similar methods involving arrays to edit or maintain
table/outline data
if the arrays in the main array are mutatable:
[[mainArray objectAtIndex:index] replaceObjectAtIndex:otherIndex
withObject:theNewObject];
//If the arrays in the main array are mutatable then you only need to
change the objects and not the whole array.
Ive used this method a number of times to replace data in drag and drops
or simply edit data in a cell without messing with the rest of an array.

Are the arrays in the arrayOfRows also mutable arrays?
