Yep. For some reason my business partner's iPhone 4S gets hammered with an
outrageous number of memory warnings, whereas my iPhone 4 rarely does. He
doesn't seem to be running anything extra in the background, either. I put
extensive logging in our app that goes to a text file, recording memory
warnings, view loads/unloads, and viewWillAppear/Disappear. This is how I
discovered the exact time to create a warning in the simulator, finally
allowing me to repro the white screen at will.
Switching to the alert view eliminated the last white screen in our case.
But with the ActionSheet, it was clear that the underlying screens were
nillified, and whichever one was revealed ended up white. Our app has two
tabs with root views, and I was able to end up with a tab bar showing but
white screen for the root of the selected tab.
