我正在尝试使用自定义填充uitableview,但出现以下错误:
Fatal error: Use of unimplemented initializer 'init(style:reuseIdentifier:)' for class 'Appname.PostCellView'
代码:
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 4
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! PostCellView
return cell
}
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(PostCellView.self, forCellReuseIdentifier: "Cell")
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
后视图单元格:(此类已加载到视图的文件所有者中)
import UIKit
protocol PostCellViewDelegate: class {
}
class PostCellView: UITableViewCell {
weak var delegate: PostCellViewDelegate?
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
let _ = commonInitialization()
}
func customise(imageName : String , color : UIColor, logoLabelValue : String, websiteValue: String)
{
}
func commonInitialization() -> UIView
{
let bundle = Bundle.init(for: type(of: self))
let nib = UINib(nibName: "PostCellView", bundle: bundle)
let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
view.frame = bounds
view.autoresizingMask = [UIViewAutoresizing.flexibleWidth, UIViewAutoresizing.flexibleHeight]
addSubview(view)
return view
}
}
请帮助我查找我的代码有什么问题以及如何纠正该代码。

请将对commonInitialization()
的调用从initWithCoder
转移到方法awakeFromNib
。同时删除initWithCoder
方法
在您的PostCellView
代码中,添加此方法并删除initWithCoder。
override func awakeFromNib() {
super.awakeFromNib()
let _ = commonInitialization()
}

覆盖init(style:reuseIdentifier:)
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
// Code
}
