ios - 如何将值传递给另一个UINavigationViewController

我有一个UIViewController，我必须将一个值（UIImage，NSString）传递给UINavigationViewController，我正在使用

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    AppDetail *advc = [segue destinationViewController];
    if ([[segue identifier] isEqualToString:@"showDetail"]) {
        advc.appTitel = name;
        advc.appIcon = icon;
        advc.detailAppName = detileName;
        advc.appDescription = description;
        advc.appDeveloper = developer;
    }
}

将该值传递给UIViewController，如果我将其直接传递给UIViewController，它可以完美地工作，但是我不能将其传递给UINavigationViewController，
有人知道我该怎么做吗？

最佳答案

我有一个来自Apple segue示例的示例代码。也许有帮助。

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"Room Create"]) {
        // Prepare the settings view where the user inputs the 'serviceType' and local peer 'displayName'
        UINavigationController *navController = segue.destinationViewController;
        SettingsViewController *viewController = (SettingsViewController *)navController.topViewController;
        viewController.delegate = self;
        // Pass the existing properties (if any) so the user can edit them.
        viewController.displayName = self.displayName;
        viewController.serviceType = self.serviceType;
    }
}
