IOS how to compare two array with different values and number of elements

Question

I have two array, array A has 4 elements and array B has 10 elements. How to compare this two array together to find out whether array A has values that contains in array B.

Here is the codes.

   for(int i = 0; i <= deepsightSig.count; i++){
    for(int p = 0; p <= feeds.count; i++){


        if(feeds[i] == deepsightSig[i]){

            badIPCount++;


        }
        else
            goodIPCount++;

    }


}

Do the arrays contain the same type of objects? Would equivalent objects compare as equal when sent the isEqual: message? — Avi

Array A and Array B contains same types of objects but different number of elements. for example array A has 4 elements but array B has 10 elements. — zac

NSMutableSet* set1 = [NSMutableSet setWithArray:array1];
NSMutableSet* set2 = [NSMutableSet setWithArray:array2];
[set1 intersectSet:set2]; //this will give you only the obejcts that are in both sets

NSArray* result = [set1 allObjects];

if result.count is greater than one it means array A have values that are in array B.
