Swift 클래스에 문제가 있습니다. UITableViewController 클래스와 UITableViewCell 클래스에 대한 신속한 파일이 있습니다. 내 문제는 UITableViewCell 클래스와 콘센트입니다. 이 클래스에는 오류가 있습니다. “HomeCell”클래스에는 초기화 프로그램이 없으며이 문제를 이해하지 못합니다.

답변 주셔서 감사합니다.

import Foundation
import UIKit

class HomeTable: UITableViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet var tableViex: UITableView!

    var items: [(String, String, String)] = [
        ("Test", "123", "1.jpeg"),
        ("Test2", "236", "2.jpeg"),
        ("Test3", "678", "3.jpeg")
    ]

    override func viewDidLoad() {
        super.viewDidLoad()

        var nib = UINib(nibName: "HomeCell", bundle: nil)
        tableView.registerNib(nib, forCellReuseIdentifier: "bookCell")
    }

    // Number row
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.items.count
    }

    // Style Cell
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("bookCell") as UITableViewCell

        // Style here

        return cell

    }

    // Select row
    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        // Select
    }

}

// PROBLEM HERE
class HomeCell : UITableViewCell {

    @IBOutlet var imgBook: UIImageView
    @IBOutlet var titleBook: UILabel
    @IBOutlet var pageBook: UILabel

    func loadItem(#title: String, page: String, image:String) {
        titleBook.text = title
        pageBook.text = page
        imgBook.image = UIImage(named: image)
    }

}

@IBOutlet var imgBook: UIImageView!

@IBOutlet var pageBook: UILabel!

class Actor {
    let agent : String? // BAD! // Its value is set to nil, and will always be nil and that's stupid so Xcode is saying not-accepted.
    // Technically speaking you have a way around it🤓, you can help the compiler and enforce your value as a constant. See Option3
}

class Actor {
    var agent : String? // It's defaulted to `nil`, but also has a chance so it later can be set to something different || GOOD!
}

class Actor {
let agent : String? // It's value isn't set to nil, but has an initializer || GOOD!

init (agent: String?){
    self.agent = agent // it has a chance so its value can be set!
    }
}

class Actor {
let agent : String? = nil // very useless, but doable.
let company: String? = "Universal"
}
