{
    "approvers": [
        [
            {
                "userId": 3,
                "userName": "Joe",

            },
            null,
            {

                "userName": "啊啊啊啊",
                "headUrl": ""
            }
        ]
    ]
}

Your model:

class LeaveApproverModel: Mappable {

    var userId: Double = 0
    var userName = ""
    var headUrl = ""

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        userId <- map["userId"]
        userName <- map["userName"]
        headUrl <- map["headUrl"]
    }
}

class LeaveApproversModel: Mappable {

    var approvers: [[LeaveApproverModel]] = [[]]

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        approvers <- map["approvers"]
    }
}

What you did:

let repo = Mapper<LeaveApproversModel>().map(myJSONDictionary)

What you expected:

I exepected something like:

{"approvers":[[LeaveApproversModel, LeaveApproversModel], [LeaveApproversModel, LeaveApproversModel]]}

What you got:

{"approvers":[[]]}
