嗨，我正在尝试使用邮箱样式平移http://www.mailboxapp.com/制作一个表格视图，因为我正在使用这个库https://github.com/gloubibou/HHPanningTableViewCell并且它工作正常，我滑动单元格它移动得很好，问题是我想在滑动单元格时触发自定义操作，而我只能在它打开然后触摸它时才能做到这一点。

这是发生动作的代码

#import "HHPanningTableViewCell.h"

@property (nonatomic, retain) NSArray *rowTitles;

@end

    }

    return self;

我知道我可以使用手势识别器来触发动作，但我认为图书馆已经在这样做了。

在这一部分中，我触发了一个动作，非常清楚地知道单元格，它在哪里平移以及单元格的背面是否显示，但总是通过单击它，因为它是一个选择功能。

- (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;
}

我相信这另一部分是应该触发自定义操作的地方，但程序永远不会进入这个函数

- (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];
}

我希望我说清楚了，并提前谢谢你。

要触发委托方法，您需要将控制器设置为单元格的委托。目前在您cellForRowAtIndexPath的控制器中，仅当directionMask为 4 时才将控制器分配为委托。因此，您要么directionMask在当前代码中设置为 4（而是根据单元格位置返回一个值），要么在每种情况下将控制器设置为委托，如我已经在下面做了。

- (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;
}

将委托方法更改为

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