Re: nstableview reload with animation possible?
Well, that method doesn't animate. Conceptually, what you have to do is this (and assuming you are using a view based table view): 1. Call beginUpdates on the table *important* 2. Modify the table to add/remove all the rows that you added or removed. Note that it works like an NSArray, so calling removeRow:3 will remove row 3, and then what was at row 4 is now at row 3. So to delete what was at row 4 you call removeRow:3 again. This is *different* from how it works on iOS which freezes the table and does not treat it like an array 3. Call endUpdates The table will not call the datasource during the time you call beginUpdates/endUpdates. corbin On Jun 18, 2012, at 5:26 PM, Rick C. rickcort...@gmail.com wrote: Thanks I will take a look!

Thanks, Hi Rick, You probably want - (void)reloadDataForRowIndexes:(NSIndexSet *)rowIndexes columnIndexes:(NSIndexSet *)columnIndexes NS_AVAILABLE_MAC(10_6); In my app, I use it to update rows which get updated one at a time but you can provide an index set with many rows.

Re: nstableview reload with animation possible?
Thanks again for the replies. Think I was able to get it to work just had to re-code a few things compared to simply using reloadData... rc On Jun 20, 2012, at 1:58 AM, Corbin Dunn wrote: Well, that method doesn't animate.

nstableview reload with animation possible?
Hi, What I'm basically trying to do is call reloadData but with animation and I can't see how to do it? I know about removing/inserting rows with animation and I tried this, but I keep crashing and I would think it's because I'm removing rows and inserting rows after my datasource has been modified. That's why normally I use reloadData and it works fine. Also, it seems there is a method to do this in iOS but it's not available on Mac. So is it possible to do this? Or can I only use the animation when removing inserting rows without changing the modifying the datasource?
