ios - Swift - 打开内置的 iOS 字典来查找词义

Question

在我的项目中，我想打开 iOS 内置词典 来查找词义，或者更好的是，直接在我的应用中获取词义。

目前我发现了如何使用 UITextChecker

检查字符串是否拼写正确

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
}

Answer 1

我找到了Objective-C的解决方案:

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

我已经为 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)
}

Swift 4也是如此:

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，此解决方案允许打开内置词典
