Scavenger Hunt

Time: 10 minutes

  • Use Xcode documentation, online searches, and personal knowlege.
  • No helping each other. You're building your own search skills. We'll discuss strategies at the end.
  • Remember, iOS changes rapidly. You're looking for the latest APIs.
  • When you're done or time is up, send your answers privately to me in Zoom.

Find:

  1. A way to call a method repeatedly, firing at n-second intervals. Bonus: How do you stop this after you've used it for a while?
  2. A class that allows you to add bolding, italics, and text color to strings.
  3. A class that lets you draw new UIImages, enabling you to set the image output dimensions and format before you start drawing.
