objective-c - 如何将下面 Objective-C 中的 JSON 转换为 Swift？

Question

我尝试将以下代码转换为

objective-c

NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding]

swift

let json = JSONSerialization.jsonObject(with: json?.data(using: String.Encoding(rawValue: String.Encoding.utf8.rawValue)), options: JSONSerialization.ReadingOptions)

但我不断收到此错误

Cannot invoke 'jsonObject' with an argument list of type '(with: Data?, options: JSONSerialization.ReadingOptions.Type)'

您也应该利用具有可选值的 Swift。试试这个。

if let data = json?.data(using: .utf8),
    let jsonObject = try? JSONSerialization.jsonObject(with: data, options: []) {
    //jsonObject
}
