    This is a simple method to compare two arrays and get all the common objects from these arrays.

    Take two arrays(say firstArray & secondArray)

    NSMutableSet* arraySet1 = [NSMutableSet setWithArray:firstArray];  //create NSMutableSet for firstArray
NSMutableSet* arraySet2 = [NSMutableSet setWithArray:secondArray];  //create NSMutableSet for secondArray

[arraySet1 intersectSet:arraySet2];     //this will assign all common(intersecting) values of two sets to arrayset1


NSArray* arrayResult = [arraySet1 allObjects]; // assign all the object of arraySet1 to arrayResult

    For Example:

    firstArray=(
    abc,
    pqr
)

secondArray=(
    abc,
    pqr
)

arrayResult is=(
    pqr
)
