This example passes data from Controller B to Controller A. Let’s rename our ViewController.swift to SourceViewController. Controllers intermediate between view and model objects. Storyboard segues are very much useful for passing data in between Source and Destination View Controllers and vice versa also. Let’s start by creating a SingleView iOS app. To share attributes and functionality across different types B. The secondary class will be able to pass data back to the base class while the two classes are decoupled. In this example we will see how a base class can hand off functionality to a secondary class using a delegate.
Passing data forward is used when you want to show some information in a detail view controller. faultCenter postNotificationName:'handleDeepLinking' object:someObject Passing Data back from one class to another (A class can be any controller, Network/session manager, UIView subclass or any other class) Blocks are anonymous functions. Delegation is a very important design pattern in iOS development. If you have a value in one view controller and want to pass it to another, there are two approaches: for passing data forward you should communicate using properties, and for passing data backwards you can either use a delegate or a block. Using delegates is a cool but a little more complicated approach for passing data between controller B to controller A (the other way around as above). Position the UITableViewController to the left of the UIViewController. Swift share data model communicate between page.
