Answer 1

在这里您可以找到示例UITextChecker

考虑下面的例子：

func isReal(word: String) -> Bool {
    let checker = UITextChecker()
    let range = NSRange(location: 0, length: word.utf16.count)
    let misspelledRange = checker.rangeOfMisspelledWord(in: word, range: range, startingAt: 0, wrap: false, language: "en")

    return misspelledRange.location == NSNotFound
}

isReal(word: "apple") //true
isReal(word: "pple")  //false

Answer 2

您的代码正常工作

func isCorrect(word:String)->Bool{
    let checker = UITextChecker()
    let range = NSRange(location: 0, length: word.utf16.count)
    let mispelledRange = checker.rangeOfMisspelledWord(in: word, range: range, startingAt: 0, wrap: false, language: "en")

    return mispelledRange.location == NSNotFound
}

print(isCorrect(word: "apple"))
print(isCorrect(word: "ppale"))
