ios - 一旦我开始滚动，我的带有自定义 xib 单元格的 UITableView 就会消失
<p><pre><code>import UIKit
class ToDoViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var DateLabel: UILabel!
@IBOutlet weak var MonthLabel: UILabel!
@IBOutlet weak var DayLabel: UILabel!
@IBOutlet weak var tableView: UITableView!

// tableView.register(nib, forCellReuseIdentifier: "customCell")
//let nib = UINib.init(nibName: "customCell", bundle: nil)
// tableView.register(nib, forCellReuseIdentifier: "customCell")
tableView.register(UINib(nibName: String(describing: CustomCell.self), bundle: nil), forCellReuseIdentifier: "customCell")
self.tableView.delegate = self
self.tableView.dataSource = self
// Do any additional setup after loading the view.

<p>这是我的整个 ViewController 类，但我无法找出为什么一旦我开始向下滚动所有数据就会消失。尽管您最初可以看到数据，但无法看到数据。我无法弄清楚为什么数据会消失以及整个文件消失的原因。下面分享了自定义的 init 方法，虽然我相信这不是改变它的实际问题。</p>
<pre><code>func customInit(name: String, time: String, completed: Bool){
self.eventName.text = name
self.lengthLabel.text = time
if(completed) {
completedImage.image = UIImage(named: "C")
} else {
completedImage.image = UIImage(named: "R")
}
//self.contentView.backgroundColor = UIColor(red: 129/255.0, green: 25/255.0, blue: 207/255.0, alpha: 1)
}
</code></pre>
<p>导入基础</p>
<p>类事件{
变量名称:字符串？
变量时间:整数？
var isComplete:bool 值？</p>
<pre><code>init(eventName: String, eventLength: Int) {
self.name = eventName
self.time = eventLength
self.isComplete = false
}
init(eventName: String, eventLength: Int, complete: Bool) {
self.name = eventName
self.time = eventLength
self.isComplete = complete
}
</code></pre>
<p>}</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您应该更改 numberOfRowsInSection 中的静态数字</p>
<p>喜欢:</p>
<pre><code>func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return ToDoViewController.ToDoEvents.count
}
</code></pre></p>
