I think the best way to look into this is that your App should not need to handle memory warnings. If it receives one, it might be too late to do anything.
The way to handle it is the same of keeping your memory usage down. Explicitly dispose all your large objects as soon as you're done with them. Pay special attention to webviews, uicontrollers and images.
