How to add an NSMutableArray to an NSMutableArray Objective-c

Question

I am making the switch from Java to Objective-c, and I'm having some difficulty. I have searched this problem this without much success.

I have an NSMutableArray that stores NSMutableArrays. How do I add an array to the array?

Thanks,

Eric

You can either store a reference to another array (or any type of object) in your array:

[myArray addObject:otherArray];

Or concatinate the arrays.

[myArray addObjectsFromArray:otherArray];

Both of which are documented in the documentation.

Since an array is just an object like any other:

[myContainerMutableArray addObject:someOtherArray];

Or if you want to concatenate them:

[myFirstMutableArray addObjectsFromArray:otherArray];

You add it like any other object.

NSMutableArray *innerArray = [NSMutableArray array];
NSMutableArray *outerArray = [NSMutableArray array];
[outerArray addObject:innerArray];
