NSScanner *scanner = [NSScanner scannerWithString:myString];
[scanner scanUpToString:@"pickey=" intoString:NULL];
if ([scanner scanString:@"pickey=" intoString:NULL]) {
    long long pickeyValue = 0;
    if ([scanner scanLongLong:&pickeyValue]) {
        // Successfully found an integer value at this position
        ...
    }
}
