Autolayout IOS 7故事板強制橫向或縱向

Question

我有一個故事板，其中大部分視圖應該是縱向模式，但一個應該處於橫向模式。我減少了大量的搜索，但一直保持一個小小的空白。

我當前實現，其不完全似乎在工作，我希望由我從這個網站拼湊下面的代碼位：

我做了一個RotationalViewController從延伸UINavigationController的

#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 

然後我做了一個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 

我有一些改變的設置，但無濟於事發揮各地。我的一般攻擊計劃是讓特定的視圖控制器從LandscapeViewController或PortraitViewController繼承，如果我想鎖定它們到一個特定的方向。

似乎縱向視圖工作（我可以將控制器鎖定到縱向視圖），但我似乎無法加載我的1橫向視圖，並讓它a）自動旋轉以加載景觀，或b）旋轉到風景在所有。

任何建議將不勝感激。

Answer 1

應用解決方案中提出：
Force controllers to Change their orientation in Either Portrait or Landscape

我能夠把事情的工作。

在我PortraiteViewController和LandscapeViewControllers都我修改viewDidLoad方法來：

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]; 
} 

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]; 
} 

此解決方案可能會在IOS7後停止工作，因爲目前的ModalViewController和dismissModalViewController已被棄用。
