Question

In the context of function repetition and setup, what code may be repeated in your app? What should be included in your function(s)? (Hint: Review the setup of the updatescreen() function in the list scrolling pattern.)

Looping structures; code to refresh UI elements.
Initialization routines; code to fetch and update data.
User input handling; code to manage UI interactions.
Error handling procedures; code to manage exceptions and crashes.

Answer 1

In app development, repeated code often includes elements for refreshing the UI, initialization routines, user input handling, and error handling procedures to ensure smooth operation and user experience.

Step-by-step explanation:

In the context of function repetition and setup within app development, certain code components tend to be repeated to ensure the app functions correctly. Notably, code to refresh UI elements is often part of looping structures, which are used to update the display as data changes or as users interact with the app. Additionally, initialization routines are crucial as they set up necessary conditions when an app starts or when a new screen is presented. These routines might include code to fetch and update data from a database or an external API. Function development should also incorporate user input handling to manage UI interactions such as button clicks, text input, and gestures. Lastly, robust error handling procedures are essential to manage exceptions and prevent crashes, ensuring a smooth user experience even when unexpected situations occur.
