UITableView is very important part of iOS ecosystem. So we split tableviews in sections. Then its easier to find right information.
1. First let’s create a project as usual. Create a new single view application X code project. Set project name to UIViewController. 2. Go to main storyboard & select view controller & use UITableView
3. Select tableview & make it initial view controller
4 Create a custom Sections Class like Name => TableSections, create register cell static return “getCellNibs” method. Then create 4 section enum “TableItems” then after append all sections to an array model.
import UIKit
struct CellNib{
static func getCellNibs() -> [String] {
return ["Cell1","Cell2","Cell3","Cell4"]
}
}
enum TableItems: Int {
case TableSections1
case TableSections2
case TableSections3
case TableSections4
}
class TableSections: NSObject {
var sectionType : TableItems?
init(tItems:TableItems) {
sectionType = tItems
}
class func sectionsForTable()->[TableSections] {
var sections = [TableSections]()
sections.append(TableSections(tItems: TableItems.TableSections1))
sections.append(TableSections(tItems: TableItems.TableSections2))
sections.append(TableSections(tItems: TableItems.TableSections3))
sections.append(TableSections(tItems: TableItems.TableSections4))
return sections
}
}
5. After Create a custom 4 UITableViewCell with xib. Cell1, Cell2, Cell3, Cell4.
import UIKit
class Cell1: UITableViewCell {
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
}
}
Same Cell2, Cell3, Cell4
6. After Create a TableCommonVC UIViewController and UITableViewDelegate, UITableViewDataSource, setup section, and register table cells.
import UIKit
class TableCommonVC: UIViewController, UITableViewDelegate, UITableViewDataSource{
var tSections: [TableSections]?
@IBOutlet weak var tlbView : UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.setupSection()
self.setTlbNibs()
self.tlbView.reloadData()
}
func setTlbNibs(){
for item in CellNib.getCellNibs() {
let nib = UINib(nibName: item , bundle: nil)
self.tlbView.register(nib, forCellReuseIdentifier: item)
}
}
func setupSection(){
self.tSections = TableSections.sectionsForTable()
}
//MARK: UITableView Delegate & DataSource
func numberOfSections(in tableView: UITableView) -> Int {
return (self.tSections != nil) ? self.tSections!.count:0
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return setRows(tItems: self.tSections![section].sectionType!)
}
func setRows(tItems: TableItems)->Int {
switch tItems {
case .TableSections1:return getS1RowCount()
case .TableSections2:return getS2RowCount()
case .TableSections3:return getS3RowCount()
case .TableSections4:return getS4RowCount()
}
}
func getS1RowCount()->Int{ return 0 }
func getS2RowCount()->Int{ return 0 }
func getS3RowCount()->Int{ return 0 }
func getS4RowCount()->Int{ return 0 }
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
return setCells(indexPath: indexPath)!
}
func setCells(indexPath: IndexPath)-> UITableViewCell? {
let tItem = tSections![indexPath.section]
switch tItem.sectionType! {
case .TableSections1:return getCellS1(indexPath: indexPath)
case .TableSections2:return getCellS2(indexPath: indexPath)
case .TableSections3:return getCellS3(indexPath: indexPath)
case .TableSections4:return getCellS4(indexPath: indexPath)
}
}
func getCellS1(indexPath:IndexPath)->UITableViewCell?{ return nil }
func getCellS2(indexPath:IndexPath)->UITableViewCell?{ return nil }
func getCellS3(indexPath:IndexPath)->UITableViewCell?{ return nil }
func getCellS4(indexPath:IndexPath)->UITableViewCell?{ return nil }
}
7. Now Create a TableSectionDemoVC for visibility tableview and override UITableView numberOfRowsInSection and cellForRowAt methods.
import UIKit
class TableSectionDemoVC: TableCommonVC{
override func viewDidLoad() {
super.viewDidLoad()
self.setTlbNibs()
self.tlbView.reloadData()
}
override func getS1RowCount()->Int{ return 1 }
override func getS2RowCount()->Int{ return 1 }
override func getS3RowCount()->Int{ return 1 }
override func getS4RowCount()->Int{ return 1 }
override func getCellS1(indexPath:IndexPath)->UITableViewCell?{
if let hCell = self.tlbView.dequeueReusableCell(withIdentifier: "Cell1") as? Cell1{
hCell.selectionStyle = .none
return hCell
}
return nil
}
override func getCellS2(indexPath:IndexPath)->UITableViewCell?{
if let hCell = self.tlbView.dequeueReusableCell(withIdentifier: "Cell2") as? Cell2{
hCell.selectionStyle = .none
return hCell
}
return nil
}
override func getCellS3(indexPath:IndexPath)->UITableViewCell?{
if let hCell = self.tlbView.dequeueReusableCell(withIdentifier: "Cell3") as? Cell3{
hCell.selectionStyle = .none
return hCell
}
return nil
}
override func getCellS4(indexPath:IndexPath)->UITableViewCell?{
if let hCell = self.tlbView.dequeueReusableCell(withIdentifier: "Cell4") as? Cell4{
hCell.selectionStyle = .none
return hCell
}
return nil
}
}
Overview
Table views in iOS display rows of vertically scrolling content in a single column. Each row in the table contains one piece of your app’s content.
