1 Washington State University School of Electrical Engineering and Computer Science Spring 2021 CptS 479 Mobile Application Development Homework 1 Due: January 27, 2021 (11:59pm) General Instructions: Put the entire app directory into one zip file and submit as an attachment under Content Homework 1 for this course on Blackboard Learn by the above deadline. Note that you may submit multiple times, but only the most recent entry submitted before the above deadline will be graded. For this homework you will implement a simple app called HealthApp that displays some soothing images to keep us healthy and happy. See screen shots below. Specifically, 1. In Xcode, create a New Project as an iOS App called HealthApp. This project should use Interface: Storyboard, Life Cycle: UIKit App Delegate, and Language: Swift. Do not check “Use Core Data”. Checking “Include Tests” is optional. 2. On the Storyboard, make sure “View as: iPhone 11 (wC hR)” is shown at the bottom. In the view, add a Label at the top of the view with the app’s name “Health App”. Below that add a Label with “Larry’s Happy Place” with your first name in place of “Larry”. These labels should be centered horizontally and constrained to be appropriately spaced at the top of the view. 3. Add an Image View to the view that is centered horizontally and vertically and constrained to be of size 256×256. Make sure the Content Mode of the Image View is “Aspect Fit”. 4. Centered at the bottom of the view, add a Button called “Next”. 5. Add at least three pleasant (G-rated) images to your project. Be sure to check “Copy items if needed” next to “Destination” if you drag-and-drop the image files into your project. 6. The basic functionality of the app is to show the images one-by-one, cycling through the images by tapping the “Next” button. When you reach the last image, tapping “Next” will restart the cycle at the first image. Be sure that the view is initialized with the first image when the app starts up. You will need to create an IBOutlet to the Image View and an IBAction for the “Next” button. See the FirstApp example in the Introduction lecture notes for some hints on how to do this. 7. Test your app using the iPhone 11 simulator, which is the same simulator we will use to grade your app. 8. Be sure that auto layout constraints are set so that the view elements are appropriately displayed with no overlap or trimming regardless of device orientation. 2 Storyboard: Simulator: 欢迎咨询51作业君
