swift tabview 带参数请求网络。多条目展示。json解析，逃逸闭包

效果：

用到的第三方

# Uncomment the next line to define a global platform for your project platform :ios, '9.0' target 'News' do # Comment the next line if you don't want to use dynamic frameworks use_frameworks! # Pods for News pod 'Alamofire' pod 'SwiftyJSON' pod 'HandyJSON' end

请求网络地址与参数

// // Const.swift // News // // Created by liuan on 2020/10/7. // import UIKit let screenWidth = UIScreen.main.bounds.width let screentHeight = UIScreen.main.bounds.height //服务器请求 let BASE_URL = "https://is.snssdk.com" let device_id:String = "6096495334" let IID:String = "5034850950"

数据bean

// // MyCellModel.swift // News // // Created by liuan on 2020/10/7. // import Foundation import HandyJSON struct MyCellModel:HandyJSON { var grey_text:String = "" var text:String = "" var url:String = "" var key:String = "" var tip_new:Int = 0 } struct MyConcern:HandyJSON { var name:String? var url:String? var total_count:Int? var description:String? var time:String? var type:String? var icon:String? var userid:Int? var is_verify:Bool? var media_id:Int? var tips:Bool? var id:Int? var user_auth_info:String? var userAuthInfo: UserAuthInfo?{ return UserAuthInfo.deserialize(from:user_auth_info) } } struct UserAuthInfo: HandyJSON { var auth_type:Int? var auth_info:String? }

 

网络请求工具类，用到了逃逸闭包，返回请求参数后刷新了网络请求

// // NetworkToolProtocol.swift // News // // Created by liuan on 2020/10/7. // import Foundation import Alamofire import SwiftyJSON protocol NetworkoolProtocol { // -----------我的mine-------- // 我的界面 cell的数据 static func loadmyCellData(completioHandler: @escaping(_ sections:[[MyCellModel]])->()) //我的关注数据 static func loadMyConcern() } extension NetworkoolProtocol{ } struct NetworkTool:NetworkoolProtocol { // -----------我的mine-------- // 我的界面 cell的数据 static func loadmyCellData(completioHandler: @escaping(_ sections:[[MyCellModel]])->()) { let url = BASE_URL + "/user/tab/tabs/?" let params = ["device_id":device_id] Alamofire.request(url,parameters: params).responseJSON{(response) in guard response.result.isSuccess else{ //d网络错误提示信息 return } if let value = response.result.value{ //swiftyjson里面的 let json = JSON(value) print(value) guard json["message"]=="success" else { return } if let data = json["data"].dictionary{ if let sections = data["sections"]?.array{ var sectionnArray = [[MyCellModel]]() for item in sections { var rows = [MyCellModel]() for row in item.arrayObject! { let myCellModel = MyCellModel.deserialize(from: row as? NSDictionary) rows.append(myCellModel!) } sectionnArray.append(rows) } completioHandler(sectionnArray) } } } } } //我的关注数据 static func loadMyConcern() { } }

主要的tabView Controller

// // MineViewController.swift // News // // Created by liuan on 2020/10/5. // import UIKit class MineViewController: UITableViewController { var sections = [[MyCellModel]]() override func viewDidLoad() { super.viewDidLoad() tableView.tableFooterView = UIView() tableView.backgroundColor = UIColor.globalBackGroundColor() tableView.register( UINib(nibName: String(describing:MyOtherCell.self), bundle: nil), forCellReuseIdentifier: String(describing:MyOtherCell.self)) //获取我的cell的数据 NetworkTool.loadmyCellData{(sections) in let string = "{\"text\":\"我的关注\",\"grey_text\":\"\"}" let myConcern = MyCellModel.deserialize(from: string) var myConcerns = [MyCellModel]() myConcerns.append(myConcern!) self.sections.append(myConcerns) self.sections+=sections self.tableView.reloadData() } } } extension MineViewController{ override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat { return 10 } override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { let view = UIView(frame: CGRect(x: 0, y: 0, width: screenWidth, height: 10)) view.backgroundColor = UIColor.globalBackGroundColor() return view } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return sections[section].count } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: MyOtherCell.self)) as! MyOtherCell let section = sections[indexPath.section] let myCellModel = section[indexPath.row] cell.leftLabel.text = myCellModel.text cell.rightLabel.text = myCellModel.grey_text return cell } override func numberOfSections(in tableView: UITableView) -> Int { return sections.count } override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { tableView.deselectRow(at: indexPath, animated: true) } }

UIColor 扩展

// // UiColorExtension.swift // geekTime // // Created by liuan on 2020/9/14. // Copyright © 2020 liuan. All rights reserved. // import UIKit extension UIColor { static func hexColor(_ hexValue:Int,alpahValue:Float)->UIColor{ return UIColor(red: CGFloat((hexValue & 0xFF0000) >> 16 ) / 255, green: CGFloat((hexValue & 0x00FF00) >> 8) / 255, blue: CGFloat(hexValue & 0x0000FF ) / 255, alpha: CGFloat(alpahValue)) } static func hexColor(_ hexValue:Int)->UIColor{ return hexColor(hexValue,alpahValue: 1) } convenience init(_ hexValue:Int,alpahValue:Float) { self.init(red: CGFloat((hexValue & 0xFF0000) >> 16 ) / 255, green: CGFloat((hexValue & 0x00FF00) >> 8) / 255, blue: CGFloat(hexValue & 0x0000FF ) / 255, alpha: CGFloat(alpahValue)) } convenience init(_ hexValue:Int) { self.init(hexValue,alpahValue:1) } convenience init(r:CGFloat,g:CGFloat,b:CGFloat,alpha:CGFloat = 1.0){ self.init(displayP3Red: r/255.0, green: g/255.0, blue: b/255.0, alpha: alpha) } class func globalBackGroundColor() -> UIColor{ return UIColor(r: 248, g: 249, b: 247) } }

用到了 MyOtherCell +xlib

// // MyOtherCell.swift // News // // Created by liuan on 2020/10/7. // import UIKit class MyOtherCell: UITableViewCell { @IBOutlet weak var leftLabel: UILabel! @IBOutlet weak var rightLabel: UILabel! @IBOutlet weak var rightImageView: UIImageView! override func awakeFromNib() { super.awakeFromNib() // Initialization code } override func setSelected(_ selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) // Configure the view for the selected state } }

xlib 不知道代码如何复制

就是这个样子的
