iphone popviewcontroll问题

这是我的代码，如何将selectedCountry和SelectedCountry1传递到profilepage

---

我尝试了，但没有得到任何值，请帮助我，如果下一个视图是

detailViewController

，则应该使用

pushViewControllerAnimated:animated:

而不是

popViewControllerAnimated:

。从逻辑上讲，push向前，pop向后

导航堆栈在《视图控制器编程指南》的一节中介绍

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Navigation logic may go here. Create and push another view controller.

    //Some code to go to the next page
    NSString *selectedCountry = [arraycountries objectAtIndex:indexPath.row];
    NSString *selectedCountry1 = [arycountries objectAtIndex:indexPath.row];
    profilepage *detailViewController = [[profilepage alloc] initWithNibName:@"profilepage" bundle:nil];

    detailViewController.selectedCountry = selectedCountry;
    detailViewController.selectedCountry1 = selectedCountry1;
    // ...
    // Pass the selected object to the new view controller.

    [self.navigationController popViewControllerAnimated:YES];

    [detailViewController release];

您是如何在下一节课中获得detailViewController安装的？但是，我收到一条警告消息，显示UINavigationControl可能不会响应popviewcontroller，，先生，我只想通过popcontroller方法将SelecedCountries和selectedcountry1传递到上一页，，，

[self.navigationController popViewControllerAnimated:detailViewController
                           animated:YES];

[detailViewController release];
