ios - 使用 UISearchBar 后打开 detailViewController

Question

我有一个 UISearchBar 用于在 tableView 中搜索一些数据，然后在搜索之后选择一行以打开 detailViewController 。为此，这些行必须保留索引路径并且在搜索后不要更改初始索引路径，否则我无法在数据库中找到正确的元素。如何保留初始的 indexPath？还有其他方法吗？

 -(void) searchExpositorsTableView{
      [searchResult removeAllObjects]; 
      //In this array there are the elements resulted after research

      for (Database *currow in self.mutableArray){
         NSLog(@"list of expositors %@", self.mutableArray);

        NSRange titleResultsRange = [currow.name rangeOfString:self.searchBar.text options: NSCaseInsensitiveSearch];;
          if (titleResultsRange.length >0) {
                [searchResult addObject:currow.name];
                /*While I build this new array every indexPath change and the database
                  can not track down the original items*/
          }
        }

    NSLog(@"%@", searchResult);
   }

   -(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath{

      if(canSelectRow){

           NSLog(@"%d", indexPath.row);
           /*the indexPath is new and the database can not track down the original items*/
           return indexPath;

       }else{
        return nil;
       }
    NSLog(@"%d", indexPath.row);
 }

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
   //Open wrong element
 }

Answer 1

这样做

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

    if(searching) // where searching is boolean YES is searching, NO if not searched any element
    {
        //get your data from searchResults and open detailViewController
        Database *currow = [searchResults objectAtIndex:indexPath.row];
        DetailViewController = detailView = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [self.navigationController pushViewController:detailView animated:YES];
        [detailView release];
    }
    else
    {
        //get your data from self.mutableArray and open detailViewController
        Database *currow = [self.mutableArray objectAtIndex:indexPath.row];
        DetailViewController = detailView = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [self.navigationController pushViewController:detailView animated:YES];
        [detailView release];
    }

}
