替换对象数组swift 5中的特定值

Question

我需要更改对象数组中的值

从API接收的选定运动的数组

更新API响应

arrSelectedID = [["slug": cricket,
"id": 1,
"banner_image": https://_1558964043.jpg,
"name": Cricket,
"icons": {
    black = "https://sport_icon_cricket_black.png";
    green = "https://sport_icon_cricket_green.png";
    grey = "https://sport_icon_cricket_gray.png";
    white = "https://sport_icon_cricket_white.png";
}],
["slug": soccer,
"banner_image": https://1558964051.jpg
"icons": {
    black = "https://sport_icon_soccer_black.png";
    green = "https://sport_icon_soccer_green.png";
    grey = "https://sport_icon_soccer_gray.png";
    white = "https://sport_icon_soccer_white.png";
},
"id": 2,
"name": Soccer]]

我的阵列

struct ObjSportsList:Codable {
    var id:Int
    var name:String
    var slug:String
    var selected:Bool?
    var icons:ObjSportsIcon
}

struct ObjSportsIcon:Codable {
    var green:String
    var grey:String
    var white:String
    var black:String
}

var arrSports:[ObjSportsList] = [] // Array which is custom object

  

以下响应显示我的自定义对象“ ObjSportsList”

arrSports = (id: 1,
name: "Cricket",
slug: "cricket",
selected: nil,
), 

(id: 2,
name: "Soccer",
slug: "soccer",
selected: nil,
),

(id: 3,
name: "Baseball",
slug: "baseball",
selected: nil,
),

我想更改“选定的”值= true，这是从“数据”中的API数组获取的ID示例：[1,3]仅更改第1和第3个selected值== true

我尝试使用以下代码，但数组未更新

                        for (index, var sports) in self.arrSports.enumerated() {
                            for selectedSports in arrSelectedID {
                                if selectedSports["id"] as! Int == sports.id {
                                    sports.selected = true
                                }
                            }

Answer 1

请参考以下代码替换对象import UIKit var pastData = [ "What was the greatest achievement you accomplished the past five years?", "2", "3", "4", "5", "6", "7", "8", "9", "10", ] var futureData = [ "What is the single most important thing to have accomplished within the next five years?", "2", "3", "4", "5", "6", "7", "8", "9", "10", ] class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } @IBAction func pastButton(_ sender: UIButton) { } @IBAction func futureButton(_ sender: UIButton) { } @IBOutlet weak var label: UILabel! } 中的特定值

Array

我使用自己的代码解决了该问题，请检查此代码

                for (index, sports) in self.arrSports.enumerated() {
                    for selectedSports in arrSelectedID {
                        if selectedSports["id"] as! Int == sports.id {
                            self.arrSports[index].selected = true
                        }
                    }
                }
