如何在IOS中将英文数字转换成中文？

func convertToChineseNumber(_ number: Int) -> String {
    let numberFormatter = NumberFormatter()
    numberFormatter.numberStyle = .spellOut
    let numberString = numberFormatter.string(from: NSNumber(value: number)) ?? ""
    
    let chineseNumberDict: [String: String] = [
        "zero": "零",
        "one": "一",
        "two": "二",
        "three": "三",
        "four": "四",
        "five": "五",
        "six": "六",
        "seven": "七",
        "eight": "八",
        "nine": "九"
    ]
    
    let chineseNumber = numberString.replacingOccurrences(of: "\\b\\w+\\b", with: chineseNumberDict, options: .regularExpression)
    
    return chineseNumber
}

let englishNumber = 123
let chineseNumber = convertToChineseNumber(englishNumber)
print(chineseNumber) // 输出：一百二十三
