Hi everyone, Can I bump this because I'm still stuck here. :-) And maybe I can ask in a new way here's what I'm trying to do:
1. Remove old rows from tableview (let's say 5) with sliding left animation 2. Update array being used as datasource (let's say now it contains 15 items) 3. Resize my window containing my table view to fit the amount of rows (setFrame:display:animate) 4. Insert my new rows (all 15 of them) with sliding right animation Problem is between steps 3 and 4 I think the the window resizing is not finished before the inserting rows step comes. So the last couple of rows do not insert with animation but they just appear as reloadData would normally do. This does not happen if the difference is rows is 0 or minimal. But in my example (from 5 to 15) it will happen. And sorry but I couldn't figure out how to use rowViewAtRow in this situation it always throws an exception. Any help would be much appreciated thanks! rc On Jun 29, 2012, at 4:26 AM, Corbin Dunn wrote: > > On Jun 28, 2012, at 4:30 AM, Rick C. <rickcort...@gmail.com> wrote: > >> Hi, >> >> Got a view-based table view and instead of using reloadData I'm removing the >> existing rows and inserting the new rows so that I can have animation.
