Title Body

I am trying to take content from one file and write it into another. I am reading fine, but I am not able to write it into another file. I have a database of words. I want to separate the words into different files based on the number of letters. All four letter words go into one file, and so on. I added a txt file called "4letter" into my resources and the following is my code: NSError *error; //READ NSString *dbFile = [[NSBundle mainBundle] pathForResource:@"words" ofType:@"txt"]; NSString *test = [NSString stringWithContentsOfFile:dbFile encoding:NSUTF8StringEncoding error:&error]; //convert from string to array NSArray *lines = [test componentsSeparatedByString:@"\n"]; NSFileHandle *logFile = nil; logFile = [NSFileHandle fileHandleForWritingAtPath:[[NSBundle mainBundle] pathForResource:@"4letter" ofType:@"txt"]]; //Test if write works for (int i=0; i<5; i++) { NSString *randomAnagram = [[lines objectAtIndex:i] lowercaseString]; [logFile writeData: [randomAnagram dataUsingEncoding: NSNEXTSTEPStringEncoding]]; }
