从故事板内的 UIViewController 加载 UIView 不起作用 [英] Load an UIView from UIViewController inside storyboard doesn't work

问题描述

我正在尝试从我的 Storyboard 内的 UIViewController 加载一个 UIView，而没有 segue.我创建了 UIViewcontroller，布局了所有东西，将它与特定的类连接起来，并设置了一个 Storyboard ID.我还将元素连接到我的类的 h.file ，现在我正在寻找一种方法来初始化这个 UIViewController 的 subview 而无需一个 segue.我一直在搜索并发现了很多以这种方式加载 UIViewController 的帖子:

I am trying to load an UIView from an UIViewController inside my Storyboard without segue. I created the UIViewcontroller, layouted everything, connected it with the specific class and set a Storyboard ID. I also connected the elements to the h.fileof my class and now I am looking for a way to initialize a subview of this UIViewController without a segue. I have been searching and found a lot of posts which loads the UIViewController this way:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
    pointVC = (PointsViewController *)[storyboard instantiateViewControllerWithIdentifier:@"PointsViewController"];

尝试像这样添加视图，视图跳转到下一个UIViewController:

Try to add the view like this, the view jumps to the next UIViewController:

pointVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:pointVC animated:YES completion:NULL];

像 addChildViewController 一样添加它也不起作用:

Adding it like addChildViewController also doesn't work:

[self addChildViewController:pointVC];

初始化后，我尝试将特定 UIViewController 内的 UIViews 之一添加到我的实际视图中，但它不起作用.如果我只使用前两行，则不会发生任何事情，UIViewController 对象内部没有 UIViews，因为 viewDidLoad 永远不会被调用.有什么想法吗?

after initializing I try to add one of the UIViews inside the specific UIViewController to my actual View but it doesn't work. There doesn't happen anything if I just use the first two lines, the UIViewController object has no UIViews inside because viewDidLoad never will be called. Any ideas?

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
pointVC = (PointsViewController *)[storyboard instantiateViewControllerWithIdentifier:@"PointsViewController"];
[self addChildViewController:pointVC];
[self.view addSubview:pointVC.viewPointsDialog];
[pointVC didMoveToParentViewController:self];

推荐答案

应该是

[self.view addSubview:pointVC.view];

代替

[self.view addSubview:pointVC.viewPointsDialog];

所以最终的工作代码应该是这样的:

So final working code should look like this:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
pointVC = (PointsViewController *)[storyboard instantiateViewControllerWithIdentifier:@"PointsViewController"];
[self addChildViewController:pointVC];
[self.view addSubview:pointVC.view];
[pointVC didMoveToParentViewController:self];

您可以在 pointVC.view 上使用 setFrame 来正确定位它.

You can use setFrame on pointVC.view to position it properly.
