Have a look at viewWillAppear/viewDidAppear and viewWillDisappear/
viewDidDisappear on the UIViewController class
You could clear out the table data on the disappear step (so you
aren't holding data you don't need) or wait for the appear phase to
set up your data before it's shown. These get called as you push and
pop the controllers. The viewdidLoad is just like it sounds. It only
gets called when the view is created or loaded from the NIB (which may
happen more than once if you have a low memory situation as, I
believe, the UIViewController can release it's view if it's not in
use). In your normal case, the view is loaded the first time and then
kept around as you move it on and off the navigation stack.

Yes, but where will call this when the ViewController is being made

The new view was filled with data previously and i need a chance to
reset
it. Could you explain in little bit more detail ?

Hi,
I try to reuse UIViewControllers in didSelectatRowIndexPath. The
new View
has a table which is filled with data eventually. Later the view
gets
popped
and when reusing the same ViewController the table shows old data.
Is
there
a way to clear the data while still reusing ViewControllers (as
recommended). I tried in viewdidLoad etc. but it seems to get
called only
once the first time the View was created.
thanks
mohan
