ios - 在 UITabBarController 中强制横向显示特定的 View Controller

Question

我在 UITabBarController 中有 5 个导航 Controller 。 UITabBarController 中的 Navigationcontroller 之一有一个Viewcontroller 始终横向显示其他所有纵向..

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

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

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

以上代码我放入NavigationController子类中。

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeLeft;
}

以上代码是我放入景观 Controller 中的。

我有 Base 作为 UIViewController 子类，我放置了这段代码

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    if ([self isKindOfClass:[LanscapeViewController class]])
        return UIInterfaceOrientationLandscapeLeft;
    else
        return UIInterfaceOrientationPortrait;
}

如果我展示该 View Controller ，它可以很好地显示该屏幕仅横向。但是，如果我将 ViewController 插入，则仍保持纵向。

Answer 1

您是否在 ViewController 中为纵向模式编写了以下代码。

    -(BOOL)shouldAutorotate
{
    return NO;
}

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

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortraitUpsideDown | UIInterfaceOrientationPortrait;
}
