Question

How do i produce a 2 dimensional NSMutable array as this:

Array:

=>[item1]=>[item1a,item1b,item1c...]
=>[item2]=>[item2a,item2b,item2c...]
...
=>[item10]=>[item10a,item10b,item10c...]

So far i’ve only been successful up to the [item1]=>[item1a,item1b,item1c…]

When i try to add more 2 dimensional array it keeps overriding the first row.

Create NSMutableArray and assign NSMutableArrays to it as its objects.

For example:

NSMutableArray * myBig2dArray = [[NSMutableArray alloc] init];

// first internal array
NSMutableArray * internalElement = [[[NSMutableArray alloc] init] autorelease];
[internalElement addObject:@"First - First"];
[internalElement addObject:@"First - Second"];
[myBig2dArray addObject:internalElement];

// second internal array
internalElement = [[[NSMutableArray alloc] init] autorelease];
[internalElement addObject:@"Second - First"];
[internalElement addObject:@"Second - Second"];
[myBig2dArray addObject:internalElement];
