tableViewCell的indexPath

Question

我有一个自定义的方法来检测对细胞图像的点击。我还希望找到图像的相关单元格的索引路径，并在函数中使用它。下面是我正在使用的：

CellforRowAtIndexPath：

UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(cellImageTapped:)];
tapped.numberOfTapsRequired = 1;
[cell.imageView addGestureRecognizer:tapped];

方法im尝试在以下位置获取索引路径：

  -(void)cellImageTapped:(id)sender {
   if(videoArray.count > 0){
       Video *currentVideo = [videoArray objectAtIndex:INDEX_PATH_OF_CELL_IMAGE];
     //do some stuff          
  }
}

我不知道如何传递索引路径。有什么想法吗？

Answer 1

简单的方法：

• 获取接触点
• ，然后获取

点处单元格的索引路径

代码是：

-(void)cellImageTapped:(id)sender {
    UITapGestureRecognizer *tap = (UITapGestureRecognizer *)sender;
    CGPoint point = [tap locationInView:theTableView];

    NSIndexPath *theIndexPath = [theTableView indexPathForRowAtPoint:point];

    if(videoArray.count > 0){
        Video *currentVideo = [videoArray objectAtIndex:theIndexPath];
        //do some stuff
    }
}

我建议用这种方式来获取具有自定义子视图的单元的indexPath -(兼容iOS 7以及所有以前版本的)

- (void)cellImageTapped:(UIGestureRecognizer *)gestureRecognizer
{
    UIView *parentCell = gestureRecognizer.view.superview;

    while (![parentCell isKindOfClass:[UITableViewCell class]]) {   // iOS 7 onwards the table cell hierachy has changed.
        parentCell = parentCell.superview;
    }

    UIView *parentView = parentCell.superview;

    while (![parentView isKindOfClass:[UITableView class]]) {   // iOS 7 onwards the table cell hierachy has changed.
        parentView = parentView.superview;
    }


    UITableView *tableView = (UITableView *)parentView;
    NSIndexPath *indexPath = [tableView indexPathForCell:(UITableViewCell *)parentCell];

    NSLog(@"indexPath = %@", indexPath);
}

向UITableViewDataSource的tableView:cellForRowAtIndexPath:方法中的UIImageView添加一个标记。

cell.imageView.tag = indexPath.row;
