单击按钮时如何在uitableview中删除行

Question

您好，我正在实施一个表格，我在其中收到请求，我要添加到我的房间列表中，作为我的室友，我有两个按钮接受和拒绝的问题在这里，当我单击接受按钮时，我希望该行从数组中删除，并且在接受请求的情况下，我还想将已删除的行值移入nextview控制器的表中。 并且在拒绝按钮的情况下，仅希望删除该行而不要将单元格的值移动到下一个视图控制器中，我正在使用情节提要实现该项目，有人可以对此有想法吗？这是cellForRowAtIndexPath:的代码cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"DefaultCell"];
    if(cell == nil) {
        cell =[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"DefaultCell"];

    }
    acceptreq = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    acceptreq.frame =CGRectMake(170, 10, 60, 30);
    rejectreq = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    rejectreq.frame =CGRectMake(240, 10, 60, 30);
    [acceptreq setTitle:@"Accept" forState:UIControlStateNormal];
    [rejectreq setTitle:@"Reject" forState:UIControlStateNormal];
    [acceptreq addTarget:self action:@selector(Acceptrequest:) forControlEvents:UIControlEventTouchUpInside];
    [rejectreq addTarget:self action:@selector(Rejectrequest:) forControlEvents:UIControlEventTouchUpInside];
    [cell addSubview:acceptreq];
    [cell addSubview:rejectreq];
    [acceptreq setTag:indexPath.row];
    cell.textLabel.text = [myarray objectAtIndex:indexPath.row];
    return cell;

}

Answer 1

简而言之，您可以点击下面的UIbutton删除选定的行：-

-(IBAction)Acceptrequest:(id)sender
{
UIButton *btn =(UIButton*)sender;

[myarray removeObjectsAtIndexes:btn.tag];
[tableView deleteRowsAtIndexPaths:myarray withRowAnimation:UITableViewRowAnimationAutomatic];

[tableVIew reloadData];
}

Answer 2

您需要实现此方法：

[tableView deleteRowsAtIndexPaths:arrayOfIndexPathsToDelete withRowAnimation:UITableViewRowAnimationAutomatic];
