ios - IOS - 修复多个标签栏和导航内的纵向视图控制器

Question

我有一个非常复杂的图表，我想在多个 TabBarController 和 NavigationController 中修复纵向 UIViewController，我在 UIViewController 中使用这段代码来修复 TabBar 和 Navigation：

@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

并且里面的这段代码确实修复了 UIViewController但它不起作用。

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

- (BOOL)shouldAutorotate
{
    return YES;
}

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

任何人都有这个问题的解决方案，感谢阅读这篇文章！

Answer 1

你的supportedInterfaceOrientations方法应该是：

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