project 0 – Values
Abstract
Create a very simple application that offers sliders to represent two values and labels that show arithmetic operations on those values.
Components
- A window with a light gray background.
- Two sliders centered in the window.
- Static X and Y labels on the left of the sliders.
- Dynamic labels on the right of the sliders that change to reflect the slider value as it changes.
- Labels that show arithmetic operations on the values that update as the sliders change. Show at least addition and multiplication operations.
Considerations
– Create the window and root view controller in the application delegate using code. Do not use storyboards. – Add the various views to the root view controllers view. Compose the view hierarchy in the application:didFinishLaunchingWithOptions: method. We will improve app architecture in later assignments. – Use the addTarget:action:forControlEvents^ method on the sliders to observe the changes of value. The action selector can be created with a string containing the method name.
