SwiftViewJSON

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

網路請求工具類，用到了逃逸閉包，返回請求引數後重新整理了網路請求

    //我的關注資料

主要的tabView Controller

    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))
       //獲取我的cell的資料
        NetworkTool.loadmyCellData{(sections) in

    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()

用到了 MyOtherCell +xlib

//

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 不知道程式碼如何複製

就是這個樣子的
