  1. POBest way to select a row after inserting it?
    text
    copied!<p>I'm working on an iOS app using the Navigation based, CoreData template. I would like to <strong>select and "scroll to visible" a row after it was inserted into the table view</strong>. Ideally i'd like to select it, deselect it and select it again, in order to get a kind of flashing effect. </p> <p>As i am using the method, that the template provaides, namely:</p> <pre><code>#pragma mark - Fetched results controller delegate - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id &lt;NSFetchedResultsSectionInfo&gt;)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationTop]; [self.tableView selectRowAtIndexPath:newIndexPath animated:YES scrollPosition:UITableViewScrollPositionMiddle]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self configureCell:[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath]withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { [self.tableView endUpdates]; } </code></pre> <p>i am a bit confused and don't know, where to put that selection code.<br> If i put a<br> <code>[tableView selectRowAtIndexPath:&lt;#(NSIndexPath *)#&gt; animated:&lt;#(BOOL)#&gt; scrollPosition:&lt;#(UITableViewScrollPosition)#&gt;]</code><br> into<br> <code>- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller</code>,<br> it selects the row, but deselects it immediately and the scrolling doesn't behave as it should either.</p>
