IOS - 在多个标签栏和导航中修复纵向视图控制器

Question

我的图表非常复杂，我想在多个TabBarController和NavigationController中修复肖像UIViewController，我在UIViewController中使用此代码修复TabBar和导航：

@implementation UINavigationController (LoginIphone)

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

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

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

@end
@implementation UITabBarController (ChannelViewController)

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // You do not need this method if you are not supporting earlier iOS Versions
    return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

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

-(BOOL)shouldAutorotate
{
    return YES;
}

@end

并且此代码内部确实修复了UIViewController ，但它不起作用。

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

- (BOOL)shouldAutorotate
{
    return YES;
}

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

任何人都有解决此问题的方法，感谢阅读本文！

Answer 1

您的supportedInterfaceOrientations方法应为：

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