将此添加到您的应用委托(delegate)

- (NSUInteger) application:(UIApplication *)application     supportedInterfaceOrientationsForWindow:(UIWindow *)window {

if ([[window.rootViewController presentedViewController] isKindOfClass:[YourViewController class]])
    return UIInterfaceOrientationMaskPortrait;
else
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

我最近发现了这一点，它对我来说效果很好。将此代码添加到您的 View Controller

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

然后在你的 viewWillAppear 添加

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    ///Disable orientation changes
    NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}
