Need to perform reloadSections after [self.tableView endUpdates] animation is running

Question

I need to perform

[[self tableView] reloadSections:[NSIndexSet indexSetWithIndex:1] withRowAnimation:UITableViewRowAnimationNone]; 

after

 - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { // The fetch controller has sent all current change notifications, so tell the table view to process all updates. [self.tableView endUpdates]; } 

animation is in progress.

I want to do it this way because I need to reconfigure some cells in a section when a cell is removed from a section. This is due to the fact that the first and last cell of the section have different backgrounds than the cells between them. One cell has a common background. If I do not reconfigure the cells remaining in the section, this may lead to akward.

Calling reloadSections during controllerDidChangeContent is too soon and fails because the cell can no longer be found.

Answer 1

If you want to pass more than one argument to a delayed method, wrap the method call in your own method:

 - (void)reloadSections { [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:1] withRowAnimation:UITableViewRowAnimationNone]; } 

Then when you want to restart:

 [self performSelector:@selector(reloadSections) withObject:nil afterDelay:.2];

How about this?

 [CATransaction begin]; [CATransaction setCompletionBlock:^{ // animation has finished }]; [tableView beginUpdates]; // do some work [tableView endUpdates]; [CATransaction commit];
