NSArray

[losingSkillz]

hello all
i have 2 questions:
first of all, what is the difference between NSArray and NSMutableArray?

my second question is that i need 5 different arrays that hold 3 integers each and also be able to save/load the arrays using NSUserDefaults.

thanks in advance:-}

contents of NSArray are static, you can't add or delete objects on it, with NSMutableArray you can add, delete, sort, etc, read the Docs..

for saving to NSUserDefaults:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:myArray1 forKey:@"myArray1"];
...
[defaults synchronize];

one last thing- how do you store information in a three dimensional array?
thanks for the help again
