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?

You can either store a reference to another array (or any type of object) in your array:
[myArray addObject:otherArray];
Or concatenate the arrays.
[myArray addObjectsFromArray:otherArray];
Both of which are documented in the documentation.

myArray.addObjects(from: otherArray as! [Any]) in swift
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];

In case if you add the same NSMutableArray Object, Like
NSMutableArray *mutableArray1 = [[NSMutableArray alloc]initWithObjects:@"test1",@"test2",@"test3",nil];
NSMutableArray *mutableArray2 = [[NSMutableArray alloc]initWithObjects:@"test4",@"test5",@"test6", nil];
mutableArray1 = [NSMutableArray arrayWithArray:mutableArray1];
[mutableArray1 addObjectsFromArray:mutableArray2];
Nslog(@"mutableArray1 : %@",mutableArray1);

yes, It will... OUTPUT: mutableArray1 : ( test1, test2, test3, test4, test5, test6 )
[YourArray addObjectsFromArray:OtherArray];
