Question

我正在尝试将UISearchcontroller成功实现到我的UITableview中但是我有以下问题，我使用indexPath.row方法将数据传递给下一个视图控制器，当我搜索时indexPath.row发生了变化，其次我使用了多个在我的tableview中我的数据的数组，所以我所做的是创建另一个数组，将所有其他数组内容保存在一个并搜索它，除了当我想传递我的数据因为indexPath .row更改而不是留在单元格（这是我需要发生的事情）。请问您可以查看我的代码，看看您是否可以提供帮助？

  //u can do this on - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath   *)indexPath method first get 

    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
      NSString *PassData = [tableData5 objectAtIndex:indexPath.row];

  //    NSString *passData = nil; //COMMENT THIS LINE SINCE IT CONTAINS SELECTED VALUE FROM SEARCH DISPLAY TABLEVIEW NO NEED TO BE ST NULL AGAIN "COMMENT THIS LINE AND TRY"
      NSString *selectedStatus = nil;
      UIImage *selectedThumbImage = nil;

  //assuming ur array's contains equal number of objects
      if([tableData containsObject:passData]) //if the search results contains an object in this array
  {
    //by using passData from search results tableview's tapped row u cn get all the below grouped tableview data now do for other array's 
    int index = [tableData indexOfObject:passData]; //get the index of selected array
    selectedStatus = [status objectAtIndex:index];  //from that index get the status data
    selectedThumbImage  = [thumbnails objectAtIndex:index];//get thumbnil image from index
  }
else if ([tableData1 containsObject:passData])
 {
    int index = [tableData1 indexOfObject:passData]; //get the index of selected array
    selectedStatus = [status1 objectAtIndex:index];  //from that index get the status data
    selectedThumbImage  = [thumbnails1 objectAtIndex:index];//get thumbnil image from index

}
else if ([tableData2 containsObject:passData])
{
    int index = [tableData2 indexOfObject:passData]; //get the index of selected array
    selectedStatus = [status2 objectAtIndex:index];  //from that index get the status data
    selectedThumbImage  = [thumbnails2 objectAtIndex:index];//get thumbnil image from index
 }
 else if (//check for otehr remaining array)
 {
  //grab all details

 }

 //at the end your passData contains title , selectedStatus contains status , and selectedThumbImage contains thumb image use it to pass 
}//end  if (tableView == self.searchDisplayController.searchResultsTableView)

使用搜索问题时IndexPath.row会发生变化吗？
