Ios UITableViewCell如何检测用户向左或向右刷卡？

我正在使用，我想知道当用户向左或向右滑动时触发的动作。

您必须在cellForRowAtIndexPath中添加手势识别器

 UISwipeGestureRecognizer* swRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwipedRight:)];
[swRight setDirection:UISwipeGestureRecognizerDirectionRight];
[cell addGestureRecognizer:swRight];

UISwipeGestureRecognizer* swLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwipedLeft:)];
[swLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
[cell addGestureRecognizer:swLeft];

然后是它的选择器方法

-(void)cellSwipedRight:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        // your code
    }
}

-(void)cellSwipedLeft:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        // your code
    }
}

您必须在CellForRowatineXpath中添加手势识别器

 UISwipeGestureRecognizer* swRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwipedRight:)];
[swRight setDirection:UISwipeGestureRecognizerDirectionRight];
[cell addGestureRecognizer:swRight];

UISwipeGestureRecognizer* swLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwipedLeft:)];
[swLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
[cell addGestureRecognizer:swLeft];

然后是它的选择器方法

-(void)cellSwipedRight:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        // your code
    }
}

-(void)cellSwipedLeft:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        // your code
    }
}

请尝试以下代码，它将适用于您：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    UISwipeGestureRecognizer* swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwiped:)];
    [swipe setDirection:UISwipeGestureRecognizerDirectionRight];
    [cell addGestureRecognizer:swipe];

    cell.textLabel.text = [NSString stringWithFormat:@"Cell %d", indexPath.row];


return cell;
    }


    - (void)cellSwiped:(UIGestureRecognizer *)gestureRecognizer 
    {
        if (gestureRecognizer.state == UIGestureRecognizerStateEnded) 
        {
            UITableViewCell *cell = (UITableViewCell *)gestureRecognizer.view;
            NSIndexPath* indexPath = [self.tableView indexPathForCell:cell];
            //..
        }
    }

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

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

    UISwipeGestureRecognizer* swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwiped:)];
    [swipe setDirection:UISwipeGestureRecognizerDirectionRight];
    [cell addGestureRecognizer:swipe];

    cell.textLabel.text = [NSString stringWithFormat:@"Cell %d", indexPath.row];


return cell;
    }


    - (void)cellSwiped:(UIGestureRecognizer *)gestureRecognizer 
    {
        if (gestureRecognizer.state == UIGestureRecognizerStateEnded) 
        {
            UITableViewCell *cell = (UITableViewCell *)gestureRecognizer.view;
            NSIndexPath* indexPath = [self.tableView indexPathForCell:cell];
            //..
        }
    }

选中此选项此方法仅识别

UIgestureRecognitizerStateEnded

State@ahmedlabib它有多个选项用于

UIgestureRecognitizerState

如开始、取消、更改、结束等。您可以尝试以下操作-（void）swipeableTableViewCell:（SWTableViewCell*）单元格滚动状态：（SWCellState）状态；“SWTableviewCell”方法感谢@wolverine这对meCheck非常有效此方法仅识别

UIgestureRecognitizerStateEnd

State@ahmedlabib它有多个选项可用于

UIgestureRecognitizerState

，如开始、取消、更改、结束等。您可以尝试此-（void）swipeableTableViewCell：（SWTableViewCell*）单元格滚动状态：（SWCellState）状态；“SWTableViewCell”的方法谢谢@wolverine这对我对@kb920说的MEA非常有效-这种方法只识别

UIgestureRecognitizerStateEnded

状态。不……正如我在你的问题中所评论的那样，它识别多个状态

UIgestureRecognitizerStateStart

，

UIgestureRecognitizerStateCancelled

，

UIgestureRecognitizerStateChanged

，

UIgestureRecognitizerStateEnded

etcIt成功了，谢谢，还为此库找到了另一个解决方案

-（void）swipeableTableViewCell:（SWTableViewCell*）单元格滚动状态：（SWCellState）state；

正如我对@kb920所说的那样-这种方法只识别

UIgestureRecognitizerStateEnded

状态。不……正如我在你的问题中所评论的那样，

UIgestureRecognitizerStateStart

，

UIgestureRecognitizerStateCancelled

，

UIgestureRecognitizerStateChanged

，

UIgestureRecognitizerStateeEnded

etcIt工作了，谢谢，还为此库找到了另一个解决方案
