Swift – 打开内置的iOS Dictionary来查找单词含义

在我的项目中,我想打开iOS内置词典来查找单词含义,甚至更好,直接在我的应用程序中获取单词的含义.

目前我发现如何使用UITextChecker检查字符串拼写是否正确

func wordIsReal(word: String) -> Bool {
    let checker = UITextChecker()
    let range = NSMakeRange(0, count(word))
    let misspelledRange = checker.rangeOfMisspelledWordInString(word, range: range, startingAt: 0, wrap: false, language: "en")

    return misspelledRange.location == NSNotFound
}

我找到了Object-C的解决方案：

if ([UIReferenceLibraryViewController    dictionaryHasDefinitionForTerm:@"word"]) {
    UIReferenceLibraryViewController* ref = 
    [[UIReferenceLibraryViewController alloc] initWithTerm:@"word"];
    [currentViewController presentViewController:ref animated:YES completion:nil];
}

我为Swift 3编辑了它：

let word = "home"
if UIReferenceLibraryViewController.dictionaryHasDefinitionForTerm(word) {
        let ref: UIReferenceLibraryViewController = UIReferenceLibraryViewController(term: word)
        self.presentViewController(ref, animated: true, completion: nil)
}

和Swift 4一样：

let word = "home"
if UIReferenceLibraryViewController.dictionaryHasDefinition(forTerm: word) {
    let ref: UIReferenceLibraryViewController = UIReferenceLibraryViewController(term: word)
    self.present(ref, animated: true, completion: nil)
}

如果单词在设备中保存的词典中有定义,则此解决方案允许打开内置字典
