快速打印NSDictionary時如何打印中文而不是unicode

Question

當我打印包含中文的NSDictionary時，Xcode控制台打印unicode，如何將unicode轉換為中文？

Answer 1

試試這個解決方案

extension Dictionary {

    var json: String {
        let errorJson = "JSON Format error "
        do {
            let jsonData = try JSONSerialization.data(withJSONObject: self, options: .prettyPrinted)
            return String(bytes: jsonData, encoding: String.Encoding.utf8) ?? errorJson
        } catch {
            return errorJson
        }
    }


}

使用代碼

let dictionary = ["name":"ahmad","age":"22","gender":"male"]

print(dictionary.json)

記錄結果：

{
"name":"ahmad",
"age":"22",
"gender":"male"
}
