如何在tableView的数据源和代理事件之外获取当前点击的是哪一行

[cpp] view plaincopy
<pre name="code" class="cpp"> NSIndexPath *indexPathOfOwnerCell = nil; 
  /* Also, make sure the selected text field is visible on the screen */ 
//获取每个section里共有多少个cell

                             tableView:self.myTableView 
                             numberOfRowsInSection:0]; 
    NSLog(@"numberOfCells=%d",numberOfCells); 
  /* So let's go through all the cells and find their accessory text fields.
   Once we have the refernece to those text fields, we can see which one of
   them is the first responder (has the keyboard) and we will make a call
   to the table view to make sure after the keyboard is displayed,
   that specific cell is NOT obstructed by the keyboard */ 
  for (NSInteger counter = 0; 
       counter < numberOfCells;
