In the Xcode, highlight the project in the Project Navigator, and select the target in the project tree. Open the Summary page, and go to the Supported Interface Orientations section. Un-click the orientations that you do not want your application to support.
在 Xcode 中，在 Project Navigator 中突出显示项目，然后在项目树中选择目标。打开“摘要”页面，然后转到“支持的接口方向”部分。取消单击您不希望应用程序支持的方向。
In the story board, choose your first view controller, go to the Attributes inspector, and set orientation to "Portrait" in the Simulated Metrics section. Now choose the second view controller, and set its orientation to "landscape".
在故事板中，选择您的第一个视图控制器，转到 Attributes 检查器，然后在 Simulated Metrics 部分将方向设置为“Portrait”。现在选择第二个视图控制器，并将其方向设置为“横向”。
In the view controller code, implement
在视图控制器代码中，实现
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
for the first view controller, and
对于第一个视图控制器，以及
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
for the second view controller. This should fix the problem for you.
对于第二个视图控制器。这应该为您解决问题。

In your case you have two VCs. So in both VC under below method just handle you orientations. and perform check against toInterfaceOrientation and return YES.
在您的情况下，您有两个 VC。因此，在下面的两个 VC 方法中，只需处理您的方向。并针对 toInterfaceOrientation 执行检查并返回 YES。
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
// For your VC1
if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
return YES;
// For your VC2
/*
if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
return YES;
*/
}
