swift - 如何在表格上创建两个不同的部分？

Question

我试图将这些数据分成两个不同的部分: – 一个部分包含运行时间超过 120 分钟的电影，另一个部分用于其余部分。

问题是我从同一个数组中提取数据。如何应用条件语句/逻辑并根据值插入到每个部分？但是，我能够从不同的数组中提取数据并插入不同的部分。请指导我。谢谢

import UIKit

class ViewController: UIViewController,
UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: 
 Int) -> Int {
    return movieList.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell : MovieCell =  tableView.dequeueReusableCell(withIdentifier: "MovieCell", for: indexPath) as! MovieCell


    let p = movieList[indexPath.row]
    cell.nameLabel.text = p.movieName
    cell.runTimeLabel.text = "\(p.runtime) mins"
    cell.movieImageView.image = UIImage(named: p.imageName)
    return cell
}


var movieList : [Movie] = []



@IBOutlet weak var tableView: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()


    movieList.append(Movie(movieName:"Oklahoma Crude",
                           movieDesc:"",
                           runtime:115,
                           imageName:"movie_oklahoma"))
    movieList.append(Movie(movieName:"Bootleggers",
                           movieDesc:"",
                           runtime:140,
                           imageName:"movie_bootleggers"))
    movieList.append(Movie(movieName:"Superdad",
                           movieDesc:"",
                           runtime:112,
                           imageName:"movie_superdad"))

 // Do any additional setup after loading the view, typically from a nib.
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete{
        movieList.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .automatic)
    }
}





@IBAction func editButton(_ sender: Any) {

    if !self.tableView.isEditing
    {
        (sender as AnyObject).setTitle("Done", for: .normal)
        tableView.setEditing(true, animated: true)
    }
    else
    {
        (sender as AnyObject).setTitle("Edit", for: .normal)
        tableView.setEditing(false, animated: true)
    }    }



func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
    let m  = movieList[sourceIndexPath.row]
    movieList.remove(at:sourceIndexPath.row)
    movieList.insert(m, at:destinationIndexPath.row)
}





func numberOfSections(in tableView: UITableView) -> Int {
    return 2
}
let headerTitles = ["More than 120 minutes", "Others"]


func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    if section < headerTitles.count {
        return headerTitles[section]
    }

    return nil
}

Answer 1

假设 120 将是​​ section = 0

func tableView(_ tableView: UITableView, numberOfRowsInSection section: 
 Int) -> Int {
     let arr120 = movieList.filter { $0.runtime >= 120 }
     let arrLess120 = movieList.filter { $0.runtime < 120 }
     return section == 0 ? arr120.count : arrLess120.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

  if indexPath.section == 0 {
       let arr120 = movieList.filter { $0.runtime >= 120 }
        ///..
  }
  else {
       let arrLess120 = movieList.filter { $0.runtime < 120 }
       ////....
  }

但这不是最好的解决方案，您可以组织您的数据源以

struct AllMovies {
      let title:String // ex. above 120
      let arr:[Movie]
}
