试图将JSON解析为swift3并显示到UILabel中

Question

如何将此数据解析为swift3并显示到UILabel中。

请有人帮我解决这个问题，因为我刚接触了我的第一个项目。提前谢谢。

{
    “Driver_Details” :[
   {
        “Staff_ID”:2,
        “Staff_Name”:”Pratyush”,
        “Student_ID”:1
        “Route_Number”:”1A”
        “Route_Name”:”Guindy”
        “Stop_Name”:”Velachery”
        “Distance_from_School”:3,
    }
]
}

试试这个。如果你打开这个作为DriverDetails.json的Documents文件夹中的本地文件，你可以试试这个：

if let path = Bundle.main.path(forResource: "DriverDetails", ofType: "json") { 
    do { 
        let jsonData = try Data(contentsOf: URL(fileURLWithPath: path), options: .mappedIfSafe) 
        if let json = try JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers) as? [String: Any] {
            if let jsonDriverDetails = json["Driver_Details"] as? [[String: Any]] {
                // Here you have an array of DriverDetails Dictionaries
                for jsonDriverDetail in jsonDriverDetails {
                    // Iterating through each Dictionary you can access the values using the key
                    staffNameLabel.text = jsonDriverDetails["Staff_Name"] as? String
                }
            }
         }
     } catch { print(error.localizedDescription) } 
 }
