Compare two arrays with the same value but with a different order

by

You can use NSCountedSet for that purpose:

- (BOOL)isSameValues:(NSArray*)array1 and:(NSArray*)array2
{
    NSCountedSet *set1 = [NSCountedSet setWithArray:array1];
    NSCountedSet *set2 = [NSCountedSet setWithArray:array2];
    return [set1 isEqualToSet:set2];
}

NSCountedSet is a collection of different objects, where each object has an associated counter with it. Therefore the result for

NSArray *array1 = @[@0,@1,@2,@3];
NSArray *array2 = @[@2,@3,@1,@0];

is YES, but for 

NSArray *array1 = @[@1,@1,@3,@3];
NSArray *array2 = @[@3,@3,@3,@1];

the result is NO.
