这就是我创建的一个继承 UINavigationController 的自定义类

自定义导航控制器.h

#import <UIKit/UIKit.h>

@interface CustomNavigationController : UINavigationController <UINavigationControllerDelegate>

@end

自定义导航控制器.m

#import "CustomNavigationController.h"

@interface CustomNavigationController ()

@end

@implementation CustomNavigationController

- (BOOL)shouldAutorotate
{
    return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
    return self.topViewController.supportedInterfaceOrientations;
}


@end

父视图控制器

- (IBAction)btnSelected:(id)sender
{
    FirstVC_New *firstVCOBJ = [[FirstVC_New alloc] initWithNibName:@"FirstVC_New" bundle:nil];

    CustomNavigationController *navController = [[CustomNavigationController alloc]initWithRootViewController:firstVCOBJ];
    navController.navigationBarHidden = YES;
    [self.navigationController presentModalViewController:navController animated:NO];
}

在按钮上单击我正在展示新的 UIViewController。我为 FirstVC_New 编写的这些代码。

#pragma mark - Orientation methods.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

- (IBAction)btnNextSelected:(id)sender
{
    SecondVC *secondVCOBJ = [[CouponDetailVC alloc]initWithNibName:@"CouponDetailVC" bundle:nil];

    CustomNavigationController *navController = [[CustomNavigationController alloc]initWithRootViewController:couponDetailVCOBJ];
    navController.navigationBarHidden = YES;

    [self.navigationController presentModalViewController:navController animated:NO];
}

我在 SecondVC 中完成的这些代码。

#pragma mark - Orientation methods.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);

}

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortraitUpsideDown;
}

现在从两种观点呈现都完美无缺。主要问题是我无法通过 SecondVC 进入主根视图

无论是这种方式

[self.parentViewController dismissModalViewControllerAnimated:NO];

或者这样

[self dismissModalViewControllerAnimated:NO];

建议我解决此问题的适当方法，如何使用 iOS 6 解决。

试试这个方法

[[[self presentingViewController] presentingViewController] dismissModalViewControllerAnimated:YES];

我希望它对您有用并将您导航到根视图控制器。
