如何控制UISearchDisplayController的表自己的观点？

Question

在我的应用程序，当我没过滤我表，当时我在一个小区，其框架的高度增加，以显示一个 UIProgressView 这显示了下载进展情况。

然而，当我过滤器的结果取控制器的数据 UISearchDisplayController, 细胞在这个过滤表景不行为以同样的方式。

相反，该单元不调整，没有显示取得的进展来看，不会触发下载，和应用程序随后崩溃。

我如何获得控制权的表看法，即被提出时，筛选的结果 UISearchDisplayController?

这里是我的 -tableView:didSelectRowAtIndexPath: 法。这是一个比较长，但其要旨是，它工作得很好，当我不搜索。

我想我需要适应这种莫名其妙，这样它可以与任何表查看/牵强的结果控制器，搜索结果的控制器是扔在这。

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

    if ([self.searchBar isFirstResponder])
        [self.searchBar resignFirstResponder];

    MyObject *_myObject = (MyObject *)[self.fetchedResultsController objectAtIndexPath:indexPath];

    if (self.isSimulatingFileHierarchy) 
    {   
        if ([_myObject isFolder]) 
        {
            ObjectsViewController *_objectsViewController = [[ObjectsViewController alloc] initWithNibName:@"ObjectsViewController" bundle:nil];
            _objectsViewController.managedObjectContext = self.managedObjectContext;
            _objectsViewController.nodeID = self.nodeID;
            _objectsViewController.nodeName = self.nodeName;
            _objectsViewController.parentObjectKey = [_myObject cleanedKey];

            if (self.parentObjectKey)
                _objectsViewController.title = [[_myObject cleanedKey] stringByTrimmingPrefix:[self.parentObjectKey stringByAppendingString:@"/"]];
            else 
                _objectsViewController.title = [_myObject cleanedKey];

            [self.navigationController pushViewController:_objectsViewController animated:YES];
            UIBarButtonItem *_backButton = [[UIBarButtonItem alloc] initWithTitle:self.title style:UIBarButtonItemStyleDone target:nil action:nil];
            self.navigationItem.backBarButtonItem = _backButton;
            [_backButton release];
            [_objectsViewController release];
        }
        else {
            //
            // If we don't have data cached for this object, we add a request for the object's bytes to the objectRequestQueue
            //

            // 2. We store the data to the Documents folder

Answer 1

在任何的表视图委托方法，可以指定是否与UISearchDisplayController的表视图，通过使用下面的检查工作检测：

if (tableView == self.searchDisplayController.searchResultsTableView) {
  // behavior specific to search display controller table view
}
else {
  // behavior specific to the original, unfiltered table view
}

Answer 2

通常，你会检查发表的看被通过 tableView:didSelectRowAtIndexPath: 等到你搜索显示控制器的"searchResultsTableView"和程序的备用行为，这种情况。

它听起来像是你的问题可能更加复杂。你可以发布的代码 tableView:didSelectRowAtIndexPath:?
