A wrapper for the NSMutableArray to act as Two Dimensional array for iOS & MAC for Objective-C

CRL2DArray

CRL2DArray is a wrapper to NSMutableArray for quickly working with Two-Dimensional arrays in objective-C.

How to Install

Simply, drop the files in your project, import in your required class and start working.

How to Use

Here is a sample code to help you get started

First, import the file where required #import "CRL2DArray.h"

Now, instantiate the class with required rows & columns

CRL2DArray *myTwoDArray = [[CRL2DArray alloc] initWithRows:5 columns:5];

Use the insertObject:atRow:column to insert objects into the array

[myTwoDArray insertObject:[NSNumber numberWithInt:1] atRow:1 column:2];

The class will raise exceptions if row or column is out of bounds as defined during initializaiton.

To retrieve an object from the array, use objectAtRow:column method.

[myTwoDArray objectAtRow:1 column:2];

Note: the method will raise exception if row or column is out of bounds.

Important ..

CRL2DArray uses string constant kCRL2DArrayEmptyKey INTERNALLY to store nil objects in array. So, in order to nilify (set nil) at particular point in array, simply insert kCRL2DArrayEmptyKey using insertObject:atRow:column method.

[myTwoDArray insertObject:kCRL2DArrayEmptyKey atRow:1 column:2];
