Yes. If you look at the NSMutableArray documentation you'll find a list of methods that can be used for sorting. They all start with the word "sort".

Apple also provides documentation on sorting arrays in the section named Sorting Arrays in Collection Programming Topics. For example, you could use the method -sortUsingSelector: this way:

NSMutableArray *names = [@[@"how", @"anderson", @"format", @"babilon"] mutableCopy];
[names sortUsingSelector:@selector(compare:)];
