ios cocoa: How to adjust the size of the popover depending on the number of rows in uitableview

Question

This is related to this question

ios filter options similar to the apple store (dropdown list)

I tried using a uitableviewcontroller instead of a pickerview as I couldn't understand how to use the picker view if I need it popping out (any info on it would be appreciated).

Now this is what I did.

I have a VC that calls out a "FilterVC". I only have one FilterVC that is called by 3 different "filter buttons", and I will just populate the VC depending on the button. The issue is, one button might have just 2 items that is needed to be shown, another one might containg up to 50. Was wondering how do I adjust the height of the popovercontroller that contains the uitableview? Also, is this the right way in dealing with popovers, 3 segues connected to one VC??? (It needed an anchor point)

Here's what it looks like

As a follow up question: Is this the right way to do it on an ipad? I feel like most people prefer the uipicker. The guy that answered my first question said it's more of a design thing. Now since I'm no designer, as a user, do you think uitableview is more appealing?

Thanks for your time!!

Answer 1

In the view that you're showing in the popover, set self.contentSizeForViewInPopover as soon as you know the size and before the view is displayed.

The main benefit of using a table view over a picker is that it has a scroll indicator so you can see how long the list of options is. Also obviously that you can control exactly how the list is displayed. So the table view should be better if it fits in with your UI style and particularly if the list of options is long.
