Is there a way to trigger the event viewDidUnload?

Question

Hello everyone

I hope manually trigger the event viewDidUnload (unload an viewcontroller). Is it possible?

Thanks

Answer 1

I don't think there's a possibility to trigger this method, because it's only called when memory is getting low. Why don't you use viewDidDisappear: or viewWillDisappear: ?

Answer 2

Just allocate lots and lots of big objects. It's bound to be called sooner rather than later, as soon as your device memory starts running low.
