如何在tableView的資料來源和代理事件之外擷取當前點擊的是哪一行

[cpp] view plaincopy
<pre name="code" class="cpp"> NSIndexPath *indexPathOfOwnerCell = nil; 
  /* Also, make sure the selected text field is visible on the screen */ 
//擷取每個section裡共有多少個cell 
  NSInteger numberOfCells = [self.myTableView.dataSource  
                             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; 
       counter++){ 
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:counter 
                                                inSection:0]; 
    UITableViewCell *cell = [self.myTableView cellForRowAtIndexPath:indexPath]; 
    UITextField *textField = (UITextField *)cell.accessoryView; 
    if ([textField isKindOfClass:[UITextField class]] == NO){ 
      continue; 
    } 
    if ([textField isFirstResponder]){ 
      indexPathOfOwnerCell = indexPath; 
        NSLog(@"indexPath.section=%d",indexPath.section); 
        NSLog(@"indexPath.row=%d",indexPath.row); 
      break; 
    } 
  }

    [self.myTableView scrollToRowAtIndexPath:indexPathOfOwnerCell
