Installation

ToolBox is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ToolBox'

Router

Router will help you to manage routes and navigation through the application.

A route is a class (in most cases a UIViewController) which implements TBRoutable protocol:

public protocol TBRoutable: class {
  static func loadController(with data: Any?, for route: String) -> UIViewController?
}

The TBRoutable protocol has a default implementation that just returns the designated initializer. If you need more control on initialization you can override it.

class HomeViewController: UIViewController, TBRoutable {
  public static func loadController(with data: Any?, for route: String) -> UIViewController? {
    //You can add some logic like data validation
    return self.init()
  }
}

Routes can be added manually:

extension TBRouter.Route {
  static let home = TBRouter.Route("home")
}

TBRouter.addRoute(.home, routableClass: HomeViewController.self)

Or from a local or a remote routes file (JSON): Routes.json

{
  "home": {
    "class" : "HomeViewController"
  },
}

if let url = Bundle.main.url(forResource: "Routes", withExtension: "json") {
  TBRouter.loadRoutes(from: url)
}

To perform a route just call x_performRoute from UIViewController:

x_performRoute(.home, presentationType: .push)
//or
x_performRoute(.home, presentationType: .modal, data: someData, animated: true)

Or just get the route's controller and perform a presentation programmatically:

let homeController = TBRouter.route(.home, with: someData)

Container

TBContainer is a key/value RAM storage

//Set
TBContainer.add(1, for: "key")
//Get
let val: Int? = TBContainer.getValue(for: "key")
//Remove
val = TBContainer.removeValue(for: "key")

Keys are associated with value type so same key can be reused

TBContainer.add(1, for: "key")
TBContainer.add("Hello", for: "key")

let val: Int? = TBContainer.getValue(for: "key") // 1
let val: String? = TBContainer.getValue(for: "key") // "Hello"

Be careful: TBContainer doesn't work with inheritance, set and get need to use the same type

TBContainer.add(myCollectionView, for: "collectionView")
let view: UIView? = TBContainer.getValue(for: "collectionView") // nil
let collectionView: UICollectionView? = TBContainer.getValue(for: "collectionView") // myCollectionView

Services

TBServices is a service container. To create a service and make it available:

• Create MyServiceProtocol protocol, witch inherits TBServiceProtocol
• Create your service which implements the previous protocol and TBServiceProtocol
• Add the service to TBServices

protocol MyServiceProtocol: TBServiceProtocol {
  // Add methods
}

final class MyService: MyServiceProtocol {
  // Add protocol implementation
  static func loadService() -> MyService {
    return MyService() // Service can be a singleton or not
  }
}

// Add service
TBServices.add(MyService.self, for: MyServiceProtocol.self)

// Retrieve service
let service: MyServiceProtocol = TBServices.retrieve()
// or
TBServices.retrieve(type: MyServiceProtocol.self)

Be careful: the service needs to be added before being retrieved

Feature flipping

You can create a new feature definition

extension TBFeature.Name {
  public static let foo = TBFeature.Name("foo")
  public static let bar = TBFeature.Name("bar")
}

And set/get feature status.

// Set
TBFeature.set(.foo, enabled: true)
TBFeature.set(.foo, enabled: false)
// Get
TBFeature.isEnabled(.foo) // false

Notification is sent when feature status did change (tbFeaturesDidChange):

NotificationCenter.default.addObserver(forName: .tbFeaturesDidChange, object: nil, queue: .main) { (notif) in
  if TBFeature.feature(.foo, matchNotification: notif) {
    // Foo feature status did change
  }
}

Printer

TBPrint allow you to print informations and toggle logging. Logger is operational only if DEBUG flag is enabled.

tbPrint("message", category: .ui)
tbDebugPrint("message", category: .ui)

To create a new category, just add:

extension TBPrint.Category {
  static let foo = TBPrint.Category("foo")
}

tbPrint("message", category: .foo)

Default Categories are :

• network
• database
• data
• file
• service
• ui
• none
• all

You can select which categories are logged:

TBPrint.categories = [PrintCategory.ui, PrintCategory.file]
//or
TBPrint.categories = [PrintCategory.all]

TBReusable

TBReusable is a protocol for cells (UICollectionView and UITableViewCell) which simplify cell registration and cell dequeue.

public class MyTableViewCell: UITableViewCell, TBReusable {

}

// Register
tableView.x_registerReusableCell(MyTableViewCell.self)

// Dequeue
let cell: MyTableViewCell = tableView.x_dequeueReusableCell(indexPath: indexPath)

Other

ToolBox contains other undocumented features like:

• Tabbar with custom tabbar items
• Pager with custom transitions
• Some extensions (Date, Array, Float, String, AVURLAsset, UIViewController...)
• UIObject

Requirements

• iOS 10.0+ / tvOS 10.0+
• Xcode 9.4+
• Swift 4.2+

Example

To run the example project, clone the repository, and run pod install from the Example directory first.
