我目前有一个 searchdisplaycontroller 设置和工作。原始表视图为标题和图像设置了一个segue，以传递给详细视图。我希望这种 segue 从搜索显示控制器发生，但这没有发生？我知道这是可能的，但似乎无法让它发挥作用？我的代码是：

- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
        [self.detailViewController setDetailItem:[[contentsList objectAtIndex:indexPath.section]
                                                  objectAtIndex: indexPath.row]];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"detailview"]) {
           self.detailViewController=segue.destinationViewController;
    }
}

@end

并在详细视图中进行设置：

- (void)setDetailItem:(id)newDetailItem
{
    if (_detailItem != newDetailItem) {
        _detailItem = newDetailItem;

        // Update the view.
        [self configureView];
    }
}

- (void)configureView
{
    // Update the user interface for the detail item.

    if (self.detailItem) {
        self.navigationItem.title = [self.detailItem objectForKey:@"name"];
        [self.detailImage setImage:[UIImage imageNamed:self.detailItem[@"image"]]];
    }
}

对于解决此问题的任何帮助，我将不胜感激:)

您可以通过从 tableView:didSelectRowAtIndexPath: 调用 performSegueWithIdentifier:sender: 从搜索显示控制器中进行 Segue：如下所示：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
     // Get the UITableViewCell that was selected
     UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];

     // Then this will call prepareForSegue:sender: with selectedCell as sender
     [self performSegueWithIdentifier:@"detailview" sender:selectedCell];  
}

然后在 prepareForSegue:sender: 你设置你的 destinationViewController 属性

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"detailview"]) {

       // Set your destinationViewController properties here

    }
}
