Question

I would like to count my NSArray object of my NSString. My NSArray has @"a", @"w" objects, and my string is @"abcdefgw". I would like to know how many times the @"w" object is there in my string.

You can use - (NSArray *)componentsSeparatedByString:(NSString *)separator, though this may have boundary issues. You can also use stringByReplacingOccurrencesOfString:withString: like this:

NSString *shortString = [myString stringByReplacingOccurrencesOfString:@"w" withString:@""];
return mystring.length-shortString.length;
