我的项目中有一个非常简单的ViewController.swift原型单元格。我没有网络操作，并且使用硬编码值填充tableview单元格中的数据。滚动时，桌面视图仍然不平滑。我无法弄清楚造成这种滞后的原因。 import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: Table view delegate and data source
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 20;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("reviewCell", forIndexPath: indexPath) as! ReviewTableViewCell
// cell!.label.text = "\(indexPath.row)"
cell.reviewerNameLabel.text = "John Smith"
cell.dateLabel.text = "12 months ago"
cell.publisherNameLabel.text = "xyz publisher"
cell.reviewTextLabel.text = "qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnmqwertyuiop1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnmqwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnmqwertyuiop1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm1234567890qwertyuiopasdfghjklzxcvbnm"
return cell
}
}

我已经使用故事板设置了tableview和prototype单元格，所以为了简化调试，我已经在github上传了项目。您可以从compiler-generated implementation
