Answer 1

The following provides an idea, which can be modified according to your own project conditions

Assume that your project has the architecture shown in the figure. You can add the following code to the order interface.

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    UINavigationController *nav = self.tabBarController.viewControllers.lastObject;
    NSMutableArray *vcs = [NSMutableArray array];
    [vcs addObject:nav.viewControllers.firstObject];
    [vcs addObject:self];
    [nav setViewControllers:vcs animated:NO];
    [self.tabBarController setSelectedIndex:self.tabBarController.viewControllers.count-1];
}
