IOS how to check the value of an array if it contains a certain value and display it out

I hava an array feed which contains a set of values when i log it out in the console. which looks like this in my log.

Final Feed : ( { hello = red; }, { hello = green; }, { hello = blue; }, { hello = blue; }, { hello = blue; }

However, when i use a for loop to loop the index to retrieve the values of "blue" and do a counting on how many "blue" it fails.

here is my codes

 - (void)parserDidEndDocument:(NSXMLParser *)parser {

        NSLog(@"Final Feed : %@",feeds);

        int count = 0;
        int i;
        NSString *value;
        for (i = 0; i < [feeds count]; i++) {
            NSString *bookTitle = [feeds objectAtIndex:i];


            if([[feeds objectAtIndex:i]  isEqual: @"{hello = blue;}"]){


             count++;


            }
                        }
NSLog(@"Total Warning count is:  %d",count);
    }

The question now is how do i loop the array name feeds which contains the value "blue" and do a count?

because feeds is array of dictionary so try following code:

NSInteger count = 0;
for (NSDictionary *feed in feeds) {
    if ([feed[@"hello"] isEqualToString:@"blue"]) {
        count++;
    }
}
NSLog(@"%ld", (long)count);
