Demo of Three20 memory warning bugs

Demo of a few bugs in Three20 that occur when iOS issues a memory warning.

To reproduce memory problems:

  • Run this app in iPhone simulator
  • Visit each of the tabs. One shows an "Empty" view; one shows an "Error" view; one shows a table view with a banner; and one shows a "Loading" view.
  • Return to the first tab
  • Hardware > Simulate Memory Warning
  • Check other tabs again

You will see that the empty view, error view, table banner, and loading view were not properly restored.
