Question

In my loop each row is examined and equal to “yes” or “no”. When the loop is finished, I want to know if I got a “yes”.

This is my code:

for( int i=0;i<[car count];i++) {
    NSDictionary *test = [car objectAtIndex:i];

    if ([[test objectForKey:@"car"] isEqualToString:[test2 objectForKey:@"red"]]) {
        NSLog(@"yes");
    } else {
        NSLog(@"no");
    }
}

just want to know how many “yes” I had in my loop

Create a an integer variable to keep track of positive matches, set it to 0 before the loop, then increment it by 1 on every positive match and after the loop check how many you got.

NSInteger somethingFound = 0;
for (int i = 0; i < [car count]; i++) {
    NSDictionary *test = [car objectAtIndex:i];

    if ([[test objectForKey:@"car"] isEqualToString:[test2 objectForKey:@"red"]]) {
        NSLog(@"yes");
        somethingFound++;
    } else {
        NSLog(@"no");
    }
}
if (somethingFound) {
    NSLog("found %d", somethingFound);
}
