iOS 6 AutoRotate在UiNavigationController中

Question

我的應用程序中有UiNavigationController。 我希望只有一個屏幕可以旋轉，所以我放入這個類：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return YES;
}

-(BOOL)shouldAutorotate {
    return YES;
}

-(NSInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

但發生的問題是在ecery屏幕上應用程序旋轉發生。 我怎么能禁用它？

Answer 1

對於iOS 6，我在我的應用程序中使用以下代碼，它允許您單獨指定每個viewcontroller的旋轉：

AppDelegate.m -

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{NSUInteger orientations =UIInterfaceOrientationMaskAllButUpsideDown;
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}

ViewController.m -

- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}

最初的代碼信用我相信去Ray Wenderlich“iOS 6 by Tutorials”一書。 Ray Wenderlich網站

在您要僅自動旋轉的類中使用以下代碼：

@interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
- (NSUInteger)supportedInterfaceOrientations;
- (BOOL)shouldAutorotate;
@end


@implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
    {
        UINavigationController *navController = (UINavigationController *) self.selectedViewController;
        if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
            return YES;
    }
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (NSUInteger)supportedInterfaceOrientations
{
    if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
    {
        UINavigationController *navController = (UINavigationController *) self.selectedViewController;
        if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
            return UIInterfaceOrientationMaskAll;
    }
    return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotate
{
    if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
    {
        UINavigationController *navController = (UINavigationController *) self.selectedViewController;
        if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
            return YES;
    }
    return NO;

}

@end

在要旋轉的類的父視圖控制器（即導航控制器堆棧中的前一個類）中使用此代碼。

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

Answer 3

在您的appDelegate中添加此代碼

@property(nonatomic,assign)BOOL shouldRotate;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    shouldRotate=NO;
}
-(void)shouldAutoRotate:(BOOL)rotate
{
    self.shouldRotate=rotate;
}

在rootview控制器中添加此代碼

#import "AppDelegate.h"
#define myAppDelegate (AppDelegate *)[[UIApplication sharedApplication] delegate]

- (NSUInteger)supportedInterfaceOrientations
{
 if(![myAppDelegate shouldRotate])
     return UIInterfaceOrientationMaskPortrait;
 else
     return UIInterfaceOrientationMaskAllButUpsideDown;
}

之后在viewcontroller.m中添加此代碼，您要旋轉它

- (void)viewDidLoad
{
    [super viewDidLoad];
    [myAppDelegate shouldAutoRotate:YES];
}

-(void)viewWillDisappear:(BOOL)animated
{
    [myAppDelegate shouldAutoRotate:NO];
}

我為我的一個項目（IOS 7）做了這個。它對我很有用。

Answer 4

您可以創建一個類別來覆蓋navigationController中的方法以支持所有類。

@implementation UINavigationController (Rotation_IOS6)

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

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

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

@end

如果要限制不同控制器中的旋轉，則覆蓋supportedInterfaceOrientations和shouldAutorote，在各個viewcontrollers中根據需要更改返回值。

Answer 5

-(NSUInteger)supportedInterfaceOrientations
{
    return self.topViewController.supportedInterfaceOrientations;

}
