Iphone 在主UIViewController的子视图中是否可以有两个导航控制器？

下图解释了我要做的事情：

这是一款iPad应用程序。可能吗？如果是这样的话，有人能发布框架代码来做吗

提前谢谢

是的，有可能。骨架代码：

头文件：

@interface SGBSplitViewController : UIViewController

@property (nonatomic, strong, readonly) UIViewController *leftViewController;
@property (nonatomic, strong, readonly) UIViewController *rightViewController;

- (id)initWithLeftViewController:(UIViewController *)leftViewController
             rightViewController:(UIViewController *)rightViewController;

@end

实施文件：

@implementation SGBSplitViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    return nil;
}

- (id)initWithLeftViewController:(UIViewController *)leftViewController
             rightViewController:(UIViewController *)rightViewController
{
    self = [super initWithNibName:nil bundle:nil];
    if (self)
    {
        _leftViewController = leftViewController;
        _rightViewController = rightViewController;
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self addChildViewController:self.leftViewController];
    [self.view addSubview:self.leftViewController.view];
    [self.leftViewController didMoveToParentViewController:self];

    [self addChildViewController:self.rightViewController];
    [self.view addSubview:self.rightViewController.view];
    [self.rightViewController didMoveToParentViewController:self];
}

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];

    self.leftViewController.view.frame = <frame>;
    self.rightViewController.view.frame = <frame>;
}

@实现SGBSplitViewController
-（id）initWithNibName:（NSString*）nibNameOrNil bundle:（NSBundle*）nibBundleOrNil
{
返回零；
}
-（id）initWithLeftViewController:（UIViewController*）leftViewController
rightViewController:（UIViewController*）rightViewController
{
self=[super initWithNibName:nil bundle:nil]；
如果（自我）
{
_leftViewController=leftViewController；
_rightViewController=rightViewController；
}
回归自我；
}
-（无效）viewDidLoad
{
[超级视图下载]；
[self addChildViewController:self.leftViewController]；
[self.view addSubview:self.leftViewController.view]；
[self.leftViewController didMoveToParentViewController:self]；
[self-addChildViewController:self.rightViewController]；
[self.view addSubview:self.rightViewController.view]；
[self.rightViewController didMoveToParentViewController:self]；
}

您尝试过UISplitViewController吗？右侧和左侧的两个导航控制器彼此独立。您尝试过UISplitViewController吗？右侧和左侧的两个导航控制器彼此独立
