Podfile

pod "MultipleTabs"

Installation with Carthage

https://github.com/Carthage/Carthage

github "PagesJaunesMobile/MultipleTabs"

Other installation

Git clone the source.

Add MultipleTabs folder to your project (or workspace).

Quick start

Import the framework :

import MultipleTabs

Create a new class and inherit from MultipleTabsViewController :

class ViewController: MultipleTabsViewController {

In viewDidLoad register the collectionViewCells you will use for each tab, and declare your dataSource MultipleTabsViewControllerDataSource :

override func viewDidLoad() {
  super.viewDidLoad()
    
  register(type: Cell1.self, identifier: "Cell1")
  register(type: Cell2.self, identifier: "Cell2")
  dataSource = self
}

The dataSource should implement 3 callbacks method :

extension ViewController: MultipleTabsViewControllerDataSource {
  
  /// The number of tabs you want
  func numberOfTabs() -> Int {
    return 2
  }
  
  /// The title for each tab
  func title(forTabIndex index: Int) -> String {
    return "Title"
  }
  
  /// Return the container cell you want for the tabIndex
  func cell(forTabIndex index: Int) -> UICollectionViewCell {
    
    let cell: UICollectionViewCell
    
    if index == 0 {
      cell = dequeue(identifier: "Cell1", index: index)
    }
    else {
      cell = dequeue(identifier: "Cell2", index: index)
    }
    
    return cell
  }
}

Customization

Some customization are available but all of them comes with default values :

  /// The height for the titles bar
  public var titlesHeight: CGFloat = 50
  
  /// The color for the bottom selected border of the tab
  public var titleBorderColor: UIColor = .black
  
  /// The height for the bottom selected border of the tab
  public var titleBorderHeight: CGFloat = 5
  
  /// The color for the title label when selected
  public var titleSelectedColor: UIColor = .black
  
  /// The color for the title label when unselected
  public var titleUnselectedColor: UIColor = .darkGray
  
  /// The font for the title label when selected
  public var titleSelectedFont: UIFont = .boldSystemFont(ofSize: 14)
  
  /// The font for the title label when unselected
  public var titleUnselectedFont: UIFont = .systemFont(ofSize: 14)
  
  /// The multiplier for the size of the bottom selected border compared of the width of the tab title
  public var borderWidthMultiplier: CGFloat = 0.8

Others

Some other dataSource callback are available :

  /// Called just before cell will be displayed
  @objc optional func willDisplay(cell: UICollectionViewCell, forTabIndex index: Int)
  
  /// Called just after cell has been displayed
  @objc optional func didEndDisplaying(cell: UICollectionViewCell, forTabIndex index: Int)
