ios – 编程嵌入UIViewController？

你可以通过编程来做到这一点,下面是一个方法,它将采用一个bool值来决定哪个视图控制器需要在容器视图中添加,然后将实例化一个对象,之后将它添加到containerView

- (void)addViewControllerToContainerView:(BOOL)addVC1
{
// Get storyboard
UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"<name of storyboard>" bundle:[NSBundle mainBundle]];
    UIViewController *viewController = nil;
    if (addVC1)
    {
// get viewController with identifier 
        viewController = [storyBoard instantiateViewControllerWithIdentifier:@"<View Controller 1 Identifier>"];
    }
    else
    {
        viewController = [storyBoard instantiateViewControllerWithIdentifier:@"<View Controller 2 Identifier>"];
    }
// lets add it to container view
    [viewController willMoveToParentViewController:self];
    [self.view addSubview:viewController.view];
    [self addChildViewController:viewController];
    [viewController didMoveToParentViewController:self];
// keep reference of viewController which may be useful when you need to remove it from container view,lets consider you have a property name as containerViewController
    self.containerViewController = viewController;
}

当您需要从容器视图控制器中删除视图控制器时,您可以执行此操作

[self.containerViewController willMoveToParentViewController:nil];  // 1   
   self.containerViewController.view removeFromSuperView];
   [self.containerViewController.view removeFromParentViewController]; 
   self.containerViewController = nil
