Question

我有一个故事板，大多数视图应该是纵向模式，但一个应该在Landscape中。我已经进行了大量的搜索，但仍然有点空白。

我当前的实现似乎并不像我希望的那样工作，包括我从这个网站拼凑的以下代码：

我做了一个 RotationalViewController ，它扩展自 UINavigationController

#import "RotationControlledViewController.h"

@interface RotationControlledViewController ()

@end

@implementation RotationControlledViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    UIInterfaceOrientation ret =  [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
    return ret;
}

@end

然后我做了一个 PortraitViewController

#import "PortraitViewController.h"

@interface PortraitViewController ()

@end

@implementation PortraitViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

和 LandscapeViewController

#import "LandscapeViewController.h"

@interface LandscapeViewController ()

@end

@implementation LandscapeViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(BOOL)shouldAutorotate
{
return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

@end

我一直在改变一些设置，但无济于事。我的一般攻击计划是让特定的视图控制器从LandscapeViewController或PortraitViewController继承，如果我想将它们锁定到特定的方向。

事情似乎适用于纵向视图（我可以将控制器锁定为纵向视图）但我似乎无法加载我的1景观视图并且a）在加载时自动旋转到横向，或者b）旋转到横向景观

非常感谢任何建议。

应用以下提出的解决方案：
Force controllers to Change their orientation in Either Portrait or Landscape

我能够让事情奏效。

在我的 PortraiteViewController 和 LandscapeViewControllers 中，我将viewDidLoad方法修改为：

<强> PortraiteViewController：

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];

    UIViewController *mVC = [[UIViewController alloc] init];
    [self presentModalViewController:mVC animated:NO];
    [self dismissModalViewControllerAnimated:NO];
}

<强> LandscapeViewController：

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];

    UIViewController *mVC = [[UIViewController alloc] init];
    [self presentModalViewController:mVC animated:NO];
    [self dismissModalViewControllerAnimated:NO];
}

此解决方案可能会在IOS7之后停止工作，因为不推荐使用 presentModalViewController 和 dismissModalViewController 。
