I found that this only happened when 51 pixels or fewer of the last row of a section were visible at the top of the screen. The row height returned was 97. So 51 was a baffling number, not being half the row height or of any other significance I could see.
Turns out that the tableview specified a row height of 97 (in the XIB), but the custom cells in it give themselves a height of 100 upon instantiation. Somehow this disparity triggered the problem. Changing the row height to 100 in the XIB's UITableView definition eliminated the artifacts. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
