中尝试过解决方案

Answer 1

在你所有的视图控制器中写下这段代码：

- (NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskAll; //allow rotate landscape, portrait
}

并在您只需要纵向的 viewconroller 中编写此代码。

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

或者你可以使用这个：

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if ([self.window.rootViewController.presentedViewController isKindOfClass: [CompareViewController class]])
    {
        CompareViewController *compareController = (CompareViewController *) self.window.rootViewController.presentedViewController;

        if (compareController.isPresented)
            return UIInterfaceOrientationMaskLandscape;
        else return UIInterfaceOrientationMaskPortrait;
    }
    else return UIInterfaceOrientationMaskPortrait;
}

Answer 2

尝试创建 UITabbarController 的扩展，然后覆盖扩展中的以下 2 个方法：

supportedInterfaceOrientations
shouldAutorotate

并且在这两种方法中：只是验证， if self.selectedIndex = 'particular index'（标签索引，你想要纵向）和 return 相应地。
