Question

I am trying to delete some rows from UITableView and here is my code…

    [self.responsesTableView beginUpdates];
    [self.responsesTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:self.processingIndexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    [self. responsesTableView endUpdates];
    noOfRsponses --;
    if (self.segFrndEveryone.selectedSegmentIndex == 0) {
        [self.arrFriendComments removeObjectAtIndex:self.processingIndexPath.row];
    }else {
        [self.arrAllComments removeObjectAtIndex:self.processingIndexPath.row];
    }

where one of the two arrays is my datasource depnding on the segment selected.
I am getting the following error and not sure how to deal with this.

The number of rows contained in an existing section after the update
(9) must be equal to the number of rows contained in that section
before the update (9), plus or minus the number of rows inserted or
deleted from that section (0 inserted, 1 deleted) and plus or minus
the number of rows moved into or out of that section (0 moved in, 0
moved out).’

Answer 1

Are you calling the removeObjectAtIndex on the correct array? Based on the error message, you haven’t actually removed an object from the datasource that the tableview is expecting you to have removed from. I’m guessing that maybe you are removing from the wrong array.

And one other thing to try: remove the object first and then do the deleteRowsAtIndexPath.
