How to access Array within Array within Array while dealing with UITableView - ios

Question

Here is the NSLog of my Structure (Each enum is a custom tableViewCell). I need to be able to show each cell in my table view.-
(
(
0,
0
),
(
4
),
(
1,
(
(
2
),
(

(

(

)
As you can see, it is an Array with 4 Array objects. Within these objects are enums, or arrays with enums. [0] has an array with two 0 enums, [1] has an array with one 4 enum, [2] has an array with one 1 enum, AND an array of arrays within that has eight enums of 2.
My question is how do I display these cells in
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
BucketListCellType type = [[[[self.presentedCells objectAtIndex:indexPath.section] objectAtIndex:indexPath.row] objectAtIndex:0] intValue];
}
is getting me an error - [__NSCFNumber objectAtIndex:]: unrecognized selector sent to instance
Here is where I am constructing that array -
-(void)showPresentedCells
{
NSMutableArray *preCells = [NSMutableArray new];
// First Section - Suggested Bucket List Images
NSMutableArray *suggestedBucketListImages = [NSMutableArray new];
[suggestedBucketListImages addObject:#(mainPhotoCellWithAddToBucketList)];
[suggestedBucketListImages addObject:#(mainPhotoCellWithAddToBucketList)];
[preCells addObject:[NSArray arrayWithArray:suggestedBucketListImages]];
// Second Section - Top Bucket List Images
NSMutableArray *topBucketListImages = [NSMutableArray new];
[topBucketListImages addObject:#(mainPhotoCell)];
[preCells addObject:[NSArray arrayWithArray:topBucketListImages]];
// Third Section - My Bucket List Images
NSMutableArray *myBucketListCategories = [NSMutableArray new];
NSMutableArray *categoryWithPictures = [NSMutableArray new];
[myBucketListCategories addObject:#(CreateNewBucketListCell)];
for (int i = 0; i <= [self.bucketListCategories count]; i++) {
[categoryWithPictures addObject:#[#(CategoryCell)]];
}
[myBucketListCategories addObject:[NSArray arrayWithArray:categoryWithPictures]];
[preCells addObject:[NSArray arrayWithArray:myBucketListCategories]];
NSMutableArray *unorganizedBucketListImages = [NSMutableArray new];
[unorganizedBucketListImages addObject:#(mainPhotoCell)];
[preCells addObject:[NSArray arrayWithArray:unorganizedBucketListImages]];
self.presentedCells = preCells;
}
Thanks for any help.

The source of the problem is that you're doing calling objectAtIndex for three levels of arrays, but that will work only where you really have three levels of structure (e.g. section 2, row 1). Everywhere else you only have two levels of structure (returning a NSNumber) and trying to call objectAtIndex with that will yield the error you describe.
What's less clear to me is what you want to show when there is only two levels of structure. But you could presumably do something like:
BucketListCellType type;
id object = self.presentedCells[indexPath.section][indexPath.row];
if ([object isKindOfClass:[NSArray class]]) {
type = [object[0] intValue];
} else {
type = [object intValue];
