Objective C for iOS

import "AadhaarValidate.h"

@implementation AadhaarValidate

int _multiplicationTable[][10] = {
    { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 },
    { 1, 2, 3, 4, 0, 6, 7, 8, 9, 5 },
    { 2, 3, 4, 0, 1, 7, 8, 9, 5, 6 },
    { 3, 4, 0, 1, 2, 8, 9, 5, 6, 7 },
    { 4, 0, 1, 2, 3, 9, 5, 6, 7, 8 },
    { 5, 9, 8, 7, 6, 0, 4, 3, 2, 1 },
    { 6, 5, 9, 8, 7, 1, 0, 4, 3, 2 },
    { 7, 6, 5, 9, 8, 2, 1, 0, 4, 3 },
    { 8, 7, 6, 5, 9, 3, 2, 1, 0, 4 },
    { 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 }
};
int _permutationTable[][10] = {
    { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 },
    { 1, 5, 7, 6, 2, 8, 3, 0, 9, 4 },
    { 5, 8, 0, 3, 7, 9, 6, 1, 4, 2 },
    { 8, 9, 1, 6, 0, 4, 3, 5, 2, 7 },
    { 9, 4, 5, 3, 1, 2, 6, 8, 7, 0 },
    { 4, 2, 8, 6, 5, 7, 3, 9, 0, 1 },
    { 2, 7, 9, 3, 8, 0, 6, 4, 1, 5 },
    { 7, 0, 4, 6, 9, 1, 3, 2, 5, 8 }
};
int _inverseTable[] = { 0, 4, 3, 2, 1, 5, 6, 7, 8, 9 };
+(BOOL)isValidateAadhaar:(NSString *)aaDhaarNumber{
    int c = 0;
    int len = (int)[aaDhaarNumber length];

    const char *numberInChar = [aaDhaarNumber UTF8String];

    for (int i = 0; i < len; ++i)
        c = _multiplicationTable[c][_permutationTable[(i % 8)][numberInCharenter code here[len - i - 1] - '0']];
    return c == 0;
}
