本文讲解的是RxSwift UITableView的
plain(只有一个section)
样式的实现
1、工程依赖库
podfile文件添加依赖库
pod 'RxSwift'
pod 'RxCocoa'
pod 'RxDataSources'
2、ViewController中添加如下代码
//
// HomeViewController.swift
// RxSwiftDemo
//

import UIKit
import SnapKit
import RxSwift
import RxCocoa
import RxDataSources
class HomeViewController: UIViewController {
let disposeBag = DisposeBag.init()
let homeModel = HomeModel()
lazy var tableView: UITableView = {
let tableview = UITableView.init(frame: self.view.bounds,style: .plain)
tableview.tableFooterView = UIView()
tableview.register(RowViewCell.classForCoder(), forCellReuseIdentifier: "resuseID")
tableview.rowHeight = 100
return tableview
}()
override func viewDidLoad() {
super.viewDidLoad()
title = "新闻"
view.backgroundColor = .white
// Do any additional setup after loading the view.
setupSubViews()
bindViewModel()
updateData()
}
func setupSubViews() {
view.addSubview(tableView)
}
func bindViewModel() -> Void {
homeModel.plainItems.bind(to: tableView.rx.items(cellIdentifier: "resuseID", cellType: RowViewCell.self)){(row, model, cell) in
cell.textLabel?.text = model.title
}.disposed(by: disposeBag)
}
func updateData() {
homeModel.updatePlainModels()
}
}
3、ViewController中用到的HomeModel.swift类
//
// HomeModel.swift
// RxSwiftDemo
//
// Created by wsj_2012 on 2020/8/7.
// Copyright © 2020 wsj_2012. All rights reserved.
//
import UIKit
import RxSwift
import RxRelay
class HomeModel: NSObject {
var plainItems = BehaviorRelay(value: [RowModel.Row.init()])
// 模拟网络请求回来数据的更新数据操作
func updatePlainModels() {
var arr: [RowModel.Row] = []
for i in 0...10 {
let m = RowModel.Row(title: "标题\(i)", subTitle: "副标题\(i)")
arr.append(m)
}
plainItems.accept(arr)
}
}
4、ViewController类中的RowViewCell
RowViewCell.swift类自行创建,继承自UITableViewCell
