  • uitableview执行deleteRowsAtIndexPaths时出错

    Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 2.  The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), 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).'

    原因是这个cell中的数据需要首先移除掉。当下指的是文字显示的部分。这样即可

    [[sectionsArray objectAtIndex:indexPath.section] removeObjectAtIndex:indexPath.row];
            [tableView beginUpdates];
            
            [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section]] withRowAnimation:UITableViewRowAnimationFade];
            [tableView endUpdates];
