Question

您好我正在尝试使用邮箱样式平移http://www.mailboxapp.com/制作一个tableview，因为我正在使用此库https://github.com/gloubibou/HHPanningTableViewCell并且它工作正常，我刷了单元格它移动得很好，问题是我想在我滑动单元格时触发自定义操作，我只能在打开时才能执行此操作然后触摸它。

这是行动发生的代码

我知道我可以使用手势识别器触发动作，但我认为图书馆已经这样做了。

在这部分中，我触发一个动作，知道细胞，它在哪里被指定，如果单元格的背面是否显示，但总是点击它，因为它是一个选择函数。

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
     NSInteger directionMask = indexPath.row;
    NSString *celda = [NSString stringWithFormat:@"%d", directionMask];

    [cell isKindOfClass:[HHPanningTableViewCell class]];
    HHPanningTableViewCell *panningTableViewCell = (HHPanningTableViewCell*)cell;


    if (directionMask == 1) {
        if (HHPanningTableViewCellDirectionRight) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Custom Action"
                                                            message:@"1"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];
        }
        if ([panningTableViewCell isDrawerRevealed]) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Custom Action"
                                                            message:@"1"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];
        }
        else{
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Custom Action"
                                                            message:@"2"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];
        }
    }


    return indexPath;
}

并且我相信这另一部分是自定义动作应该被触发但是程序永远不会进入这个功能

- (void)panningTableViewCellDidTrigger:(HHPanningTableViewCell *)cell inDirection:(HHPanningTableViewCellDirection)direction
{

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Custom Action"
                                                    message:@"You triggered a custom action"
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
}

我希望我能让自己明确并提前感谢你。

Answer 1

将委托方法更改为

- (void)panningTableViewCell:(HHPanningTableViewCell *)cell didTriggerWithDirection:(HHPanningTableViewCellDirection)direction;

Answer 2

要触发委托方法，您需要将控制器设置为单元格的委托。当前在您的cellForRowAtIndexPath中，仅当directionMask为4时，控制器才被指定为委托。因此，您要在当前代码中将directionMask设置为4（这将返回基于单元格的值相反的位置）或者你在每种情况下都将控制器设置为委托，正如我在下面所做的那样。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    HHPanningTableViewCell *cell = (HHPanningTableViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    NSInteger directionMask = indexPath.row % 5;


    if (cell == nil) {
        cell = [[HHPanningTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                              reuseIdentifier:CellIdentifier];

        UIView *drawerView = [[UIView alloc] initWithFrame:cell.frame];

        // dark_dotted.png obtained from http://subtlepatterns.com/dark-dot/
        // Made by Tsvetelin Nikolov http://dribbble.com/bscsystem
        drawerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"dark_dotted"]];

        cell.drawerView = drawerView;       
    }

    if (directionMask < 3) {
        cell.directionMask = directionMask;
    }
    else {
        cell.directionMask = HHPanningTableViewCellDirectionLeft + HHPanningTableViewCellDirectionRight;

        // previous code
        //if (directionMask == 4) {
        //    cell.delegate = self;
        //}
    }
    cell.delegate = self;

    cell.textLabel.text = [self.rowTitles objectAtIndex:directionMask];

    return cell;
}
