Join Károly Nyisztor for an in-depth discussion in this video Project overview, part of Swift 4: Protocol-Oriented Programming.
- [Instructor] To save us some time, I created a single…U iOS project to begin with.…The project can be found on the desktop,…Exercise Files, Chapter 4, 4-2, start.…I'm going to copy the project to the desktop…so that we have a working copy of it.…Now, let's open the project.…Let's take a look at the storyboard file first.…
Our app has a basic user interface.…We've got a couple of labels and a text field.…I've also added auto layout constraints so…that our UI looks acceptable at runtime.…This text field is where we enter the city name.…The UI label below the text field will…display the weather information.…I've assigned a IBOutlet so that we can access it…in the ViewController.…Now, let's switch to the ViewController code.…
The input text field's delegate is our ViewController.…The text field will notify the ViewController…about editing events.…I created a UITextFieldDelegate extension to…keep the ViewController's code clean.…The textfieldshouldreturn delegate method…gets called when the user taps the Return key.…
