Ios 未获取用于在UITableViewCell中点击UISwitch的indexPath

我在一个UITableViewCell中添加了一个UISwitch，表内容是动态的，这意味着在一个tableview中可能有许多UISwitch，我需要获取每个UITableViewCell的UISwitch状态，但不能在

accessoryButtonTappedForRowWithIndexPath

方法中获取

indexPath

我的代码是：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    LocationCell *cell = (LocationCell *)[tableView 
                                          dequeueReusableCellWithIdentifier:@"LocationCell"];

    UISwitch *useLocationSwitch = [[UISwitch alloc] initWithFrame:CGRectZero];
    [cell addSubview:useLocationSwitch];
    cell.accessoryView = useLocationSwitch;

    [useLocationSwitch addTarget: self
               action: @selector(accessoryButtonTapped:withEvent:)
     forControlEvents: UIControlEventTouchUpInside];

    return cell;
}

- (void) accessoryButtonTapped: (UIControl *) button withEvent: (UIEvent *) event
{
    NSIndexPath * indexPath = [showLocationTableView indexPathForRowAtPoint: [[[event touchesForView: button] anyObject] locationInView: showLocationTableView]];
    if ( indexPath == nil )
        return;

    [showLocationTableView.delegate tableView: showLocationTableView accessoryButtonTappedForRowWithIndexPath: indexPath];
}

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
    NSLog(@"index path: %@", indexPath.row);
}

控制事件应为

UIControlEventValueChanged

不

UIControlEventTouchUpInside

。更改该选项，然后重试

因此，动作设置语句应如下所示：

[useLocationSwitch addTarget: self
                      action: @selector(accessoryButtonTapped:withEvent:)
            forControlEvents: UIControlEventValueChanged];

编辑：

- (void) accessoryButtonTapped: (UIControl *) button withEvent: (UIEvent *) event
{
    UISwitch *switch1 = (UISwitch *)button;
    UITableViewCell *cell = (UITableViewCell *)switch1.superview;
    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];

    //NSIndexPath * indexPath = [showLocationTableView indexPathForRowAtPoint: [[[event touchesForView: button] anyObject] locationInView: showLocationTableView]];
    if ( indexPath == nil )
        return;

    [showLocationTableView.delegate tableView: showLocationTableView accessoryButtonTappedForRowWithIndexPath: indexPath];
}

仍然没有得到索引值我已经更新了我的答案。它没有经过测试。一旦我进入mac电脑，我会很快（几分钟）对它进行测试。是的，它已经过测试，应该会给出预期值。在iOS 7中使用它CGPoint switchPositionPoint=[sender convertPoint:CGPointZero toView:[self tableView]]；nsindepath*indepath=[[self tableView]indexPathForRowAtPoint:switchPositionPoint]；
