iPhone: All animation stopped working after a while

Question

I've gotten some strange behavior lately. All animation suddenly stops working sometimes. Sometimes everything runs smooth, and other times this happens. Pushing and popping views just snaps into place, UITableView cellrow animation doesn't work.

The app uses a lot of background threads so maybe there is something in there?

I can't really post code since I don't know where the problem is.

Has anyone had the same problem?

Answer 1

Could that be you attempting to update UI/animate in different background threads?

Try?

dispatch_async(dispatch_get_main_queue(), ^{
  // code to update ui or start animation
});
