Question

I’m loading strings from a preloaded core data database which happen to be all CAPITAL.

I want to check if each word is in the English dictionary, and if so try to lowercase it like a regular sentence, if not keep it upper case (for abbreviations and such).

Is there a way to do this with iOS 4?

Implementation for Noah’s answer:

-(BOOL) isDictionaryWord:(NSString*) word 
{
    UITextChecker *checker = [[UITextChecker alloc] init];
    NSLocale *currentLocale = [NSLocale currentLocale];
    NSString *currentLanguage = [currentLocale objectForKey:NSLocaleLanguageCode];
    NSRange searchRange = NSMakeRange(0, [word length]);
    NSRange misspelledRange = [checker rangeOfMisspelledWordInString:word range: searchRange startingAt:0 wrap:NO language: currentLanguage ];
    return misspelledRange.location == NSNotFound;
}

NSString string = @"lalala";
if ([self isDictionaryWord:string]) string = [string lowercaseString];
