Answer 1

This can be done by using one NSMutableArray.The main point to be remembered is that the larger array should be saved in NSMutableArray. Otherwise it wont work as expected. The code is given below.

NSArray *array1 = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil];
NSArray *array2 = [NSArray arrayWithObjects:@"Two", @"Three", @"One", nil];
NSMutableArray *intermediate = [NSMutableArray arrayWithArray:array1];
[intermediate removeObjectsInArray:array2];
NSUInteger difference = [intermediate count];//returns the number of difference between two arrays.
