OOP-Cards Simple Views

Objectives

  1. Use Storyboard to layout a view controller
  2. Link labels and buttons in storyboard to a view controller's class file.
  3. Write the implementation for IBActions to change the text displayed in UILabels.

Introduction

In this lab we're going to turn the canvas of a view controller into a representation of a playing card. You'll see that our FICard class has been imported from previous labs, and the FISCardSwitcherViewController is already setting up a few cards for us to use.

Instructions:

Open the OOPCardsSimpleView.xcworkspace file and navigate to the storyboard file. You'll see an empty view controller that's already connected to the FISCardSwitcherViewController class.

  1. Create three UILabels on the view controller canvas:
  • one in the upper-left hand corner,
  • one in the bottom-right hand corner, and
  • one right in the center.
    Leave a little bit of room at the bottom for a row of UIButtons that we'll add later.

  1. Set the accesibility label of each of these UILabels to be topLabel, middleLabel, and bottomLabel respectively. This is how our tests determine which label is which. Set !N as the default text in each. Increase the font size of the middle label to something greater than 40.

  2. Now, add four UIButtons to the bottom of the canvas in a row:

  • set the button title to ♠️3 and the accessibility label to threeOfSpadesButton,
  • set the button title to ♣️4 and the accessibility label to fourOfClubsButton,
  • set the button title to ♦️8 and the accessibility label to eightOfDiamondsButton,
  • set the button title to ♥️10 and the accessibility label to tenOfHeartsButton.
  1. Connect the IBActions for these four buttons and write their implementations so that when one is pressed, all three of the UILabels update their text to show the cardLabel for the card that matches that button. The tests should pass when you have done this correctly.

Note: If you have trouble copy/pasting the suit characters from the README, you can also find them in the test files.
