iPhone目标c：检测一个“真实”字 [英] iPhone objective-c: detecting a 'real' word

问题描述

我需要一个（快速和肮脏的）解决方案来基本检测某个NSString是否是一个真实的单词，也就是说，如果它在字典中。所以基本上，一个非常简单的拼写检查。有人知道有什么办法吗？基本上，我需要一个包含英文字典中的所有单词的文件（我搜索过，但无济于事），或者与iPhone手机拼写检查服务接口的方式。当然，我想以类似于OSX上的NSSpellChecker的方式与iPhones拼写检查服务进行接口，所以我的应用程序可以与其他语言一起使用，但是在这一点上，我可以拿到我可以获得的东西。

I need a (quick and dirty) solution to basically detect if a certain NSString is a 'real' word, that is, if it's in the dictionary. So basically, a very simplistic spell checker. Does anyone know of any way to do this? Basically I either need a file containing all words in the English dictionary (which I've searched for, but to no avail), or a way to interface with the iPhones spell checking service. Of course I would like to interface with the iPhones spell check service in a similar way to NSSpellChecker on OSX so my app will work with other languages, but at this point I'll take what I can get.

最后，这里有一些伪代码来更好地说明我的需求：

Lastly, here's some pseudo-code to better illustrate my needs:

-(BOOL)isDictionaryWord:(NSString*)word;  //returns TRUE when word=@"greetings". returns FALSE when word=@"slkfjsdkl";

推荐答案

使用 UITextChecker 。下面的代码可能不是完美的，但应该给你一个好主意。

Use UITextChecker instead. The code below might not be perfect but should give you a good idea.

-(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;
}
