我在这样的方法中附加一个UISwipeGestureRecognizera :UITableViewCellcellForRowAtIndexPath:

- (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] autorelease];

        UISwipeGestureRecognizer *gesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipe:)];
        gesture.direction = UISwipeGestureRecognizerDirectionRight;
        [cell.contentView addGestureRecognizer:gesture];
        [gesture release];
    }
    return cell;
}

但是,该didSwipe方法在成功滑动时始终被调用两次.我最初认为这是因为手势开始和结束,但如果我注销gestureRecognizer本身,它们都处于"结束"状态:

-(void)didSwipe:(UIGestureRecognizer *)gestureRecognizer {

    NSLog(@"did swipe called %@", gestureRecognizer);
}

安慰:
