FXBlurView blocks MainThread

mathiasAichinger commented 11 years ago

Hi! I used the FXBlurView in different ViewController which are embedded in a PageViewController. I disabled dynamic during swiping to avoid a strange crash. And now if I swipe very fast between the VCs the app gets in a freezed state and I have to reset the app!

Does anyone have an idea? It looks like updateAsynchronously never stops!

(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; self.blurView.dynamic = YES; }
(void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; self.blurView.dynamic = NO; }

This issue also happened when I used a scrollView and the ScrollView delegate methods!

Try using the global [FXBlurView setBlurEnabled:] methods to disable the blur during animation, rather than toggling the dynamic property.

When using scrollView delegate methods to update the blur view, make sure you use the async option.
