ios - 如何快速在主数组中添加子数组

Question

{
    "firstName": "AA",
    "lastName": "BB,
    "shortName": "CC",
    "nric": "12/AAA(N)123456",
    "gender": "F",
    "dob": "1.1.2000",
    "password": "admin123",
    "photo": {
        "image": "hello",
        "thumb": "world"
    }
}

有没有办法在主数组中添加照片数组？我做了如下

let photoArray = [
    "image": imageBase64,
    "thumb": imageBase64
]

let param = [
    "firstName": txtFirstName.text as! AnyObject,
    "lastName": txtLastName.text as! AnyObject,
    "shortName": txtShortName.text as! AnyObject,
    "nric":"",
    "gender": genderCode,
    "dob":txtDOB.text as! AnyObject,
    "photo": photoArray
]

但是输出很糟糕。请告诉我怎么做。

不是让参数 let 成为 var 并执行以下操作。您确实需要指定字典类型，如下所示

let photoArray : [String : AnyObject] = [
            "pic" : "myPhoto"
        ]
var param : [String : AnyObject] = [
            "name" : "UserName"
        ]

param["photo"] = photoArray
