mutableCopy copies by reference, not value. So, any change to one of those objects affects for both arrays.

You could realize different methods to overcome this situation.

// first method

nameArray2 = [NSMutableArray new];
[nameArray2 addObjectsFromArray:nameArray1];

// second method

nameArray2 = [[NSMutableArray alloc] initWithArray:nameArray1 copyItems:YES];

Best regards.
