Question

当我使用动画重新加载几个单元格时，在其他一些非动画单元格之间会出现空格。然而，最有趣的是它有时会发生，有时却不会发生。以下代码来自tableView委托的didselect函数。

 NSArray *taskArray;
    int count ;
    if (array.count >= indexPath.row+1) {
        taskArray = [[dictionary objectForKey:[NSString stringWithFormat:@"Week %i",indexPath.section+1]] objectForKey:[array objectAtIndex:indexPath.row]];
        count = [taskArray count];
    }else{

        count = 0;

    }
    numberOfAddedRows = count;

    selectedRow = -1;
    selectedSection = -1;


    int numberOfRows = [[[dictionary objectForKey:[NSString stringWithFormat:@"Week %i",indexPath.section+1]] allKeys] count];

    [self.tableView beginUpdates];





    /*for (int i = numberOfRows-1+numberOfAddedRows; i > indexPath.row; i--) {
     [array addObject:[NSIndexPath indexPathForRow:i-1 inSection:indexPath.section]];
     }*/

    if (!editMode) {


       [array__ removeAllObjects];
        for (int i =  indexPath.row+numberOfAddedRows; indexPath.row < i; i--) {

            [array__ addObject:[NSIndexPath indexPathForRow:i inSection:indexPath.section]];
        }




        [self.tableView deleteRowsAtIndexPaths:array__ withRowAnimation:UITableViewRowAnimationMiddle];



    }else{

        [array__ removeAllObjects];
        for (int i =  indexPath.row+numberOfAddedRows+1; indexPath.row < i; i--) {
            [array__ addObject:[NSIndexPath indexPathForRow:i inSection:indexPath.section]];
        }


        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

        UITextField *textField = (UITextField*)[cell viewWithTag:2];
        [textField resignFirstResponder];




        [self.tableView deleteRowsAtIndexPaths:array__ withRowAnimation:UITableViewRowAnimationMiddle];



    }





    [self.tableView endUpdates];

     [self.tableView reloadData];

你为什么要这最后一行？

 [self.tableView reloadData];

尝试删除它 - 我认为它会干扰动画。
