Creating a custom activity indicator in Swift allows you to tailor the appearance and behavior of your loading spinner to fit the style of your app. Here's a step-by-step guide to creating a simple custom activity indicator using UIView Step 1: Create a New Swift File for the Custom Activity Indicator Create a new Swift file and name it RotatingCirclesView.swift . Add the following code to define a custom UIView subclass for your activity indicator: // // RotatingCirclesView.swift // Welcome In // // Created by Praveen Kumar on 05/09/24. // import UIKit class RotatingCirclesView : UIView { let circle1 = UIView ( frame : CGRect ( x : 20 , y : 20 , width : 60 , height : 60 )) let circle2 = UIView ( frame : CGRect ( x : 120 , y : 20 , width : 60 , height : 60 )) let position : [ CGRect ] = [ CGRect ( x : 30 , y : 20 , width : 60 , height : 60 ), CGRect ( x : 60 , y : 15 ,...
Multiple sections in UITableView iOS Swift.
UITableView is very important part of iOS ecosystem. So we split tableviews in sections. Then its easier to find right information.
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.For example, the Contacts app displays the name of each contact in a separate row, and the main page of the Settings app displays the available groups of settings.
You can configure a table to display a single long list of rows, or you can group related rows into sections to make navigating the content easier. :- https://developer.apple.com/documentation/uikit/uitableview
