的UITabBarController presentmodal自動旋轉問題

Question

我有UITabBarController子類處理旋轉問題：

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

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

-(BOOL)shouldAutorotate{ 
    return YES; 
} 

從 tabbatcontroller的 UIViewController的一個

，現在我提出一個新的UIViewController：

MainVC *mainVC = [[MainVC alloc] initWithNibName:@"MainVC" bundle:nil]; 
UINavigationController *mainNav = [[UINavigationController alloc] initWithRootViewController:mainVC]; 

radioNav.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
[self presentModalViewController:mainNav animated:YES]; 

而且在這個新的導航，我想禁用自動旋轉，只允許肖像：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{ 
    return NO; 
} 

-(NSUInteger)supportedInterfaceOrientations{ 
    return UIInterfaceOrientationMaskPortrait; 
} 

-(BOOL)shouldAutorotate{ 
    return NO; 
} 

但旋轉仍然工作，當我旋轉屏幕的應用程序轉到橫向屏幕，我該如何解決這個問題？

Answer 1

你也應該繼承UINavigationController並把下面的代碼在你的子類：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    // You do not need this method if you are not supporting earlier iOS Versions 
    return (interfaceOrientation == UIInterfaceOrientationPortrait); 
} 

-(NSUInteger)supportedInterfaceOrientations 
{ 
    return UIInterfaceOrientationMaskPortrait; 
} 

-(BOOL)shouldAutorotate 
{ 
    return NO; 
} 

然後，初始化您的子類的實例：

MainVC *mainVC = [[MainVC alloc] initWithNibName:@"MainVC" bundle:nil]; 
MYSubclassedNavigationController *mainNav = [[MYSubclassedNavigationController alloc] initWithRootViewController:mainVC]; 

radioNav.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
[self presentModalViewController:mainNav animated:YES];
