iOS，UITabBarController 中的问题

Question

我的bug如下:

在 ViewList 中，我有下面的代码，它会推送 ViewManager；

- (Void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath
{
     PropertyManagerViewController propertyManagerViewController * = [[PropertyManagerViewController alloc] initWithNibName: @ "PropertyManagerViewController" bundle: nil];
     [self.navigationController pushViewController: propertyManagerViewController animated: YES];

}

在 ViewManager 中创建 UITabBarController:

- (void) createTabBarController
{
       [ ShowTabBarController showTabBar : self.navigationController.tabBarController ] ;

        NSMutableArray * viewControllers = [ [ NSMutableArray alloc ] init ] ;
         UITabBarController * TabBarController = [ [ UITabBarController alloc ] init ] ;

        ViewController * viewController = [ [ ViewController alloc ] initWithNibName : @ " ViewController " bundle: nil ] ;
         UINavigationController * navigationController = [ [ UINavigationController alloc ] initWithRootViewController : ViewController ] ;
         [ ViewControllers addObject : navigationController ] ;

        ViewController2 viewController2 * = [ [ VisitDetailsViewController alloc ] initWithNibName : @ " ViewController2 " bundle: nil ] ;
         UINavigationController * navigationController2 = [ [ UINavigationController alloc ] initWithRootViewController : ViewController2 ] ;
         [ ViewControllers addObject : navigationController2 ] ;

         tabBarController.viewControllers = viewControllers ;
         self.navigationController.tabBarController.viewControllers = tabBarController.viewControllers ;

} .

在 ViewController 和 View ViewController2 中有这个方法来推送 ViewList。

-(void)pushTableList
{
    [ShowTabBarController hideTabBar:self.tabBarController];

    PropertyListViewController *propertyList = [[PropertyListViewController alloc] initWithNibName:@"PropertyListViewController" bundle:nil];    

[UIView beginAnimations:nil 上下文:NULL];

    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.75];
    [self.navigationController pushViewController:propertyList animated:NO];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.navigationController.view cache:NO];

    [UIView commitAnimations];
}

我现在的问题是:

• 当我在 ViewController2 pushTableList 中时，我要查看列表。
• 然后选择另一行，执行 push ViewManager，显示的 View 是最后一个 View ，在本例中是 ViewController2。

更新:

我想单击表格单元格，然后推送 ViewController。问题是:我点击单元格，当我推送到 ViewList 时， View 显示 ViewContoller 2(这是我的最后一个 View )。

新更新

1 - 推送并创建 UITabBArController

-(Void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath
{
    PropertyManagerViewController propertyManagerViewController * = [[PropertyManagerViewController alloc] initWithNibName: @ "PropertyManagerViewController" bundle: nil];
    [self.navigationController pushViewController: propertyManagerViewController animated: YES];

}
- (void) createTabBarController
{
    [ ShowTabBarController showTabBar : self.navigationController.tabBarController ] ;

    NSMutableArray * viewControllers = [ [ NSMutableArray alloc ] init ] ;
    UITabBarController * TabBarController = [ [ UITabBarController alloc ] init ] ;

    ViewController * viewController = [ [ ViewController alloc ] initWithNibName : @ " ViewController " bundle: nil ] ;
    UINavigationController * navigationController = [ [ UINavigationController alloc ] initWithRootViewController : ViewController ] ;
    [ ViewControllers addObject : navigationController ] ;

    ViewController2 viewController2 * = [ [ VisitDetailsViewController alloc ] initWithNibName : @ " ViewController2 " bundle: nil ] ;
    UINavigationController * navigationController2 = [ [ UINavigationController alloc ] initWithRootViewController : ViewController2 ] ;
    [ ViewControllers addObject : navigationController2 ] ;
    ViewController3 viewController3 * = [ [ VisitDetailsViewController alloc ] initWithNibName : @ " ViewController3 " bundle: nil ] ;
    UINavigationController * navigationController3 = [ [ UINavigationController alloc ] initWithRootViewController : ViewController2 ] ;
    [ ViewControllers addObject : navigationController3 ] ;

    tabBarController.viewControllers = viewControllers ;
    self.navigationController.tabBarController.viewControllers = tabBarController.viewControllers ;

}

2 - 选择 TabBarITem Visit Details 然后点击 UIBarButtonItem Property List

3 - 单击 da 表的单元格。

4 - 这是我的问题。如果你回头去tabbaritem访问。我要你给我看 PropertyItem

您可能想查看此文档:https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/AboutViewControllers/AboutViewControllers.html

一条非常重要的信息:UITabBarController 始终必须是顶级 Controller !不允许将 UITabBarController 放在 UINavigationController 中。但是，您可以将 UINavigationController 放在 UITabBarController 中。 Apple docs关于 UINavigationController 的 pushViewController:animated: 方法说:

The view controller that is pushed onto the stack. This object cannot be an instance of tab bar controller and it must not already be on the navigation stack.

我希望这能为您指明正确的方向。
