的UITabBarController presentmodal自动旋转问题

Question

我有UITabBarController子类处理旋转问题：

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

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

-(BOOL)shouldAutorotate{ 
    return YES; 
} 

从 tabbatcontroller的 UIViewController的一个

，现在我提出一个新的UIViewController：

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

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

而且在这个新的导航，我想禁用自动旋转，只允许肖像：

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

-(NSUInteger)supportedInterfaceOrientations{ 
    return UIInterfaceOrientationMaskPortrait; 
} 

-(BOOL)shouldAutorotate{ 
    return NO; 
} 

但旋转仍然工作，当我旋转屏幕的应用程序转到横向屏幕，我该如何解决这个问题？

Answer 1

你也应该继承UINavigationController并把下面的代码在你的子类：

-(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; 
} 

然后，初始化您的子类的实例：

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

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