在从.xib创建的UIViewController中添加一个ContainerView

我有一个.xib文件,我想添加一个容器视图(放在ViewController中)。不幸的是,容器视图只能通过故事板一次性使用。但是当我创建一个.xib文件并且我搜索容器视图控制器时,我没有找到它。有人可以给我一些如何实现我的任务的提示吗?

如果您使用的是xib而不是storyboard,则只需将UIView添加到xib即可充当容器。然后在代码中,添加childViewController' s view作为容器的子视图。在这里,我遵循了相应的子视图控制器方法并添加了布局约束,以确保其框架更新与容器的框架:

- (void)viewDidLoad {
    [super viewDidLoad];

    UIViewController *childViewController = ...; // create your child view controller

    [self addChildViewController:childViewController];
    [self.containerView addSubview:childViewController.view];
    [childViewController didMoveToParentViewController:self];

    NSArray *horzConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|[childView]|"
                                                                   options:0
                                                                   metrics:nil
                                                                     views:@{@"childView" : childViewController.view}];

    NSArray *vertConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|[childView]|"
                                                                   options:0
                                                                   metrics:nil
                                                                     views:@{@"childView" : childViewController.view}];

    [self.view addConstraints:horzConstraints];
    [self.view addConstraints:vertConstraints];

    childViewController.view.translatesAutoresizingMaskIntoConstraints = NO;
}

检查一下:

SelectDateViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"selectDateVCID"];
[self addChildViewController:vc];
[vc.view setFrame:CGRectMake(0.0f, 0.0f, self.selectDateContainerView.frame.size.width, self.selectDateContainerView.frame.size.height)];
[self.selectDateContainerView addSubview:vc.view];
[vc didMoveToParentViewController:self];
