What is the best practice for memory management is swapping out pdf files? For example, i have a reader view controller in a container in a split view controller. the detail view controller has a list of documents the user can load similar to your fastPdf app. How do you swap documents without ballooning the amount of memory every time?

When I load a new document or leave the tab, i call

[self.pdfReader actionDismiss:nil]; [document emptyCache]; self.pdfReader=nil;
document=nil;

then i create new instances using the factory methods.

I never see a decrease in the amount of memory used. In fact it continues to climb as i change documents.

Can you recommend a better way to keep the memory usage low?
