ios - Swift json 删除键

Question

我想在没有“结果”选项卡的情况下解析我的 json 文件我的新 json 文件

[
  {
    "Id": 708,
    "Name": "My name",
    "ImageUrl": "2016728135316.jpg"
  }

下面的代码

   private func getMoviesFromJSON(jsonData: NSData) throws -> [Movie] {
        var movies = [Movie]()
        do {
            if let jsonObject = try NSJSONSerialization.JSONObjectWithData(jsonData, options: .AllowFragments) as? [String: AnyObject], jsonArray = jsonObject["results"] as? [[String: AnyObject]] {
                for i in jsonArray {
                    var properties = [String: AnyObject]()
                    properties[JSONKeys.id] = i[JSONKeys.id]
                    properties[JSONKeys.title] = i[JSONKeys.title]
                    properties[JSONKeys.posterPath] = i[JSONKeys.posterPath]
                    let movie = Movie(properties: properties)
                    movies.append(movie)
                }
            }
        } catch {
            throw TMDBErrors.ParsingError
        }
        return movies
    }

我认为必须更改此行或必须删除。

jsonObject["results"]

我需要你的帮助，谢谢!

你的 json 没有任何 results 参数..所以你根本不需要它..

     do {
        if let jsonArray = try NSJSONSerialization.JSONObjectWithData(jsonData, options: .AllowFragments) as? [[String: AnyObject]] {
            for i in jsonArray {
                var properties = [String: AnyObject]()
                properties[JSONKeys.id] = i[JSONKeys.id]
                properties[JSONKeys.title] = i[JSONKeys.title]
                properties[JSONKeys.posterPath] = i[JSONKeys.posterPath]
                let movie = Movie(properties: properties)
                movies.append(movie)
            }
        }
    } catch {
        throw TMDBErrors.ParsingError
    }
