UITableViewCellAccessory Disappears When Scrolled Off Screen

Question

I have a UITableView filled with objects. In the didSelectRowAtIndexPath method i have a UITableViewCellAccessoryCheckmark appear when the row is selected and disappea

Answer 1

Your cells get re-used as you scroll through the data (that's what the dequeueReusableCellWithIdentifier does). Your cell that got a checkmark in didSelectRowAtIndexPath gets recycled for a different row and no longer has any connection to the checked row.

You need to set/unset the accessory view in cellForRowAtIndexPath so when the checked rows scroll back into view, they get checked appropriately.
