Ios 在UITableview单元格上滑动手势，就像Whtsapp对“的滑动手势一样；回复一条消息；

如何在tableview单元格上实现滑动手势，并在手指从左向右移动时移动tableview单元格

我可以添加滑动手势，但移动单元格是我想要实现的

Whatsapp

在回复消息时实现了相同的功能，并希望获得相同的动画效果

任何帮助都将不胜感激

谢谢

我已经为此制作了一个演示。你可以用

我已将PanGesture添加到Tableviewcell中：

- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath {
    UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"Cell"];
    UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panGestureCellAction:)];
    pan.delegate = self;
    [cell.contentView addGestureRecognizer:pan];
    return cell;
}

- (IBAction)panGestureCellAction:(UIPanGestureRecognizer *)recognizer {
    CGPoint translation = [recognizer translationInView:self.view];
    if (recognizer.view.frame.origin.x < 0) { return; }
    recognizer.view.center = CGPointMake(recognizer.view.center.x+ translation.x,
                                         recognizer.view.center.y );
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];
    if(recognizer.view.frame.origin.x > [UIScreen mainScreen].bounds.size.width * 0.9)
    {
        [UIView animateWithDuration:0.25 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
            [recognizer.view setFrame: CGRectMake(0, recognizer.view.frame.origin.y, recognizer.view.frame.size.width, recognizer.view.frame.size.height)];
        } completion:nil];
    }
    if (recognizer.state == UIGestureRecognizerStateEnded)

        } completion:^(BOOL finished) {
            if (x > recognizer.view.frame.size.width / 2) {
                [_txtField becomeFirstResponder];
            }
        }];
    }

    CGPoint velocity = [panGestureRecognizer velocityInView:_tblView];

您好，用swift。我不能执行。“-（BOOL）GestureRecognitizer shouldBegin:（UIPangestureRecognitizer*）PangestureRecognitizer”始终是“GestureRecognitizer shouldBegin（uugestureRecognitizer:UIGestureRecognitizer）->BOOL”@famfam我添加了swift代码。请核实。
