this is the delete method
if(editingStyle == UITableViewCellEditingStyleDelete){
[tableTitles removeObjectAtIndex:[indexPath row]];
[self leaveEditMode];
[[self tableView] reloadData];

Answer 1

I believe you are missing the call to:
[self.tableView deleteRowsAtIndexPaths:indexPath
withRowAnimation:UITableViewRowAnimationFade];
and you don't need the reloadData call:
if (editingStyle == UITableViewCellEditingStyleDelete) {
[tableTitles removeObjectAtIndex:[indexPath row]];
[self.tableView deleteRowsAtIndexPaths:#[indexPath]
withRowAnimation:UITableViewRowAnimationFade];
[self leaveEditMode];
(this will also look better as it will give visual feedback to the user; unlike reloadData).
