Insert and delete cells and sections in uitableview

Insert segment:

-(Void) insertsections :( nsindexset *) Sections withrowanimation :( uitableviewrowanimation) animation;

-(Void) deletesections :( nsindexset *) Sections withrowanimation :( uitableviewrowanimation) animation;

Insert row:

-(Void) insertrowsatindexpaths :( nsarray *) indexpaths withrowanimation :( uitableviewrowanimation) animation;

-(Void) deleterowsatindexpaths :( nsarray *) indexpaths withrowanimation :( uitableviewrowanimation) animation;

If you re-write this method in edit mode:

 1 - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 2 { 3     if (editingStyle == UITableViewCellEditingStyleDelete) { 4         // Delete the row from the data source 5         if (indexPath.row == 0) { 6             [self.modeInfomation removeObjectAtIndex:indexPath.section]; 7             [self.modeNameArr removeObjectAtIndex:indexPath.section]; 8             NSIndexSet *sectionIndex = [NSIndexSet indexSetWithIndex:indexPath.section]; 9             [self.tableView deleteSections:sectionIndex withRowAnimation:UITableViewRowAnimationLeft];10         }11         else {12             [[self.modeInfomation objectAtIndex:indexPath.section] removeObjectAtIndex:indexPath.row];13             [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];14         }15     }   16     else if (editingStyle == UITableViewCellEditingStyleInsert) {17         // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view18     }   19 }

In normal mode:

1 [self.tableView beginUpdates];2     [[self.modeInfomation objectAtIndex:tag] addObject:@"hehe"];3     NSIndexPath *indexpath = [NSIndexPath indexPathForRow:row + 1 inSection:tag];4     [self.tableView insertRowsAtIndexPaths:@[indexpath] withRowAnimation:UITableViewRowAnimationRight];5     [self.tableView endUpdates];

Note:

Insert or delete rows or segments, update datasource first, and then insertrows or insertsections! Update both!
