Creating a two dimensional array in Objective-C

Question

Whats the easiest way to declare a two dimensional array in Objective-C? I am reading an matrix of numbers from a text file from a website and want to take the data and place it into a 3x3 matrix.

Once I read the URL into a string, I create an NSArray and use the componentsSeparatedByString method to strip of the carriage return line feed and create each individual row. I then get the count of the number of lines in the new array to get the individual values at each row. This will give mw an array with a string of characters, not a row of three individual values. I just need to be able to take these values and create a two dimensional array.

If it doesn't need to be an object you can use:

float matrix[3][3];

to define a 3x3 array of floats.
