视频播放地址：Swift零基础学习之用TableView做个景点App

1. 创建一个新项目，我就叫Yanjing

2. 将照片素材拖拽到Assets.xcassets中

3. 添加navigation controller,点击editor->embed in >Navigation Controller

4. 拖拽一个tableview，并配置constrain

5. 拖拽一个tableview cell,并配置高度为90，custom

6. 添加imageview 并配置constrain，左12，width 132，Vertically in container

7. 添加label，并配置constrain,左12，右12，height 25，Vertically in container

8. 创建一个swift文件，起名为JingDian，代码如下

import Foundation
import UIKit

class JingDian {
    var image:UIImage
    var title:String
    
    init(image:UIImage, title:String ){
        self.image = image
        self.title = title
    }
}

9. 创建一个UITableViewCell ,命名为JingCell，具体代码如下

import UIKit

class JingCell: UITableViewCell {
    
   
    func setVideo(jingDian: JingDian) {
        jingImageView.image = jingDian.image
        jingTitleLabel.text = jingDian.title
    }
    
}

10. 配置tablecell class,identifier为JingCell

11. 添加IBOutlet,imageview 设置为jingImageView，label设置为jingTitleLabel

12. 创建一个ViewController 名为JingListScreen,并配置对应class

13. 将下面的代码复制到JingListScreen.swift文件上

import UIKit

class JingListScreen: UIViewController{
    
    
    @IBOutlet weak var tableView: UITableView!
    
    var videos: [JingDian] = []
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        videos = createArray()
    }
    
    
    func createArray() -> [JingDian] {
        var objArray:[JingDian]=[]
        let briefData = [
            [
                "title":"居庸叠翠",
                "image":"001_jydc.jpg",
            ],
            [
                "title":"玉泉流虹（玉泉趵突）",
                "image":"002_yqch.jpg",
            ],
            [
                "title": "太液晴波",
                "image": "003_tyqf.jpg"
            ],
            [
                "title": "琼岛春云",
                "image": "004_cqcy.jpg"
            ],
            [
                "title": "蓟门飞雨（蓟门烟树）",
                "image": "005_jfys.jpg",
            ],
            [
                "title": "西山积雪",
                
                "image": "006_xsjx.jpg"
            ],
            [
                "title": "卢沟晓月",
                "image": "007_lgxy.jpg"
            ],
            [
                "title": "金台夕照",
                "image": "008_jtxz.jpg"
            ],
        ]
        for briefItem in briefData{
            let videoItem=JingDian(
                image: UIImage(imageLiteralResourceName:briefItem["image"]!),
                title: briefItem["title"]!
            )
            objArray.append(videoItem)
        }
        
        return objArray
        
        
    }
}


extension JingListScreen: UITableViewDataSource, UITableViewDelegate {
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return videos.count
    }
    
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let video = videos[indexPath.row]
        let cell = tableView.dequeueReusableCell(withIdentifier: "JingCell") as! JingCell
        cell.setVideo(jingDian: video)
        
        return cell
    }
}

14. 添加tableview的IBOutlet和delegate

15. 设置一下imageview上下的间隔

16. 运行App，查看效果
