Question

我在创建的所有单元格顶部都有黑色视图，当用户点击某个单元格时，其alpha值会变为0.0f。

我一直在努力的是，单元格重用标识符，因此当我更改某个单元格的某些内容时，其他一些单元格内容也会被编辑，因为它们共享相同的indexPath。

如何访问某个特定单元格的内容？

这就是我正在做的事情 -

UITapGestureRecognizer *videoGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(moveVideoPlayer:)];
[self.optionView addGestureRecognizer:videoGesture];



-(void)moveVideoPlayer:(UITapGestureRecognizer *)tap {

     CGRect visibleRect = (CGRect){.origin = self.tableView.contentOffset, .size = self.view.bounds.size};
     CGPoint visiblePoint = CGPointMake(CGRectGetMidX(visibleRect), CGRectGetMidY(visibleRect));
     NSIndexPath *visibleIndexPath = [self.tableView indexPathForRowAtPoint:visiblePoint];

     self.visibleIndex = (int)visibleIndexPath.row;

     SearchCell *cell = (SearchCell *)[self.tableView cellForRowAtIndexPath:visibleIndexPath];
     NSLog(@"object ID : %@",cell.objectId);


     cell.greyView.alpha = 0.0f;

}

Answer 1

 -(void) moveVideoPlayer:(UITapGestureRecognizer *)tap
  {
       CGPoint location = [tap locationInView:tableView];
      NSIndexPath *indexPath = [tableView  indexPathForRowAtPoint:location];
       UITableViewCell *tapCell = [tableView cellForRowAtIndexPath:swipedIndexPath];

     //Your own code...
 }

试试这个..
