var wg sync.WaitGroup

// var anotherBalance int

func code1() {
    mu.Lock()
    defer mu.Unlock()
    fmt.Println("Entering code1")
    time.Sleep(1 * time.Second)
    fmt.Println("Exiting code1")
}

func code2() {

无论如何如何在主阵列中添加照片数组？我已完成以下操作

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

但输出很糟糕。请让我怎么做。

Answer 1

而不是让参数let使其成为var并执行以下操作。您需要指定字典类型，如下所示

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

param["photo"] = photoArray

Answer 2

    let photoArray = [[
        "image": "a",
        "thumb": "b"],[
            "image": "a",
            "thumb": "b"]
    ]
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

希望你想这样。

Answer 3

let photoArray:[String:UIImage] = [
    "image": UIImage.init(named: "a.png")!,
    "thumb": UIImage.init(named: "b.png")!
]

let param:[String:AnyObject] = [
    "firstName": "AA",
    "lastName": "BB",
    "shortName": "CC",
    "nric": "",
    "gender": 0,
    "dob": "DD",
    "photo": photoArray
]

你可以这样做
