Android迅速将iOS的模拟片段化 [英] Android fragments analog in iOS's swift

问题描述

我正在Swift中迈出第一步(已完成3天)，并且需要Android片段之类的东西

I'm making my first steps in Swift (3 days into it) and need something like Android's fragments

我需要做什么:

使用自己的控制器在xib中有一些视图，并将它们充气到某个视图容器中，以便它们可以填充所有容器.

have some views in xibs with it's own controllers and inflate them to some view container so they could fill all the container.

例如，我有一个菜单会出现在iPad上屏幕的左侧，而在iPhone上，该菜单将隐藏在抽屉中.通过点击菜单项，我将需要的Fragment填充到一个容器中，在iPad的情况下，它占据屏幕右侧的3/4，在iPhone的情况下，它占据整个屏幕.

For example, I have a menu that will be in a left side of the screen on an iPad, and on iPhone this menu will be hidden in a drawer. By tapping on a menu item I inflate needed Fragment into a container that in the case of iPad takes 3/4 of the right side of the screen and in the case of iPhone it takes full screen.

通过这种方法，我不必担心Fragment视图显示在何处，它占据屏幕的哪一部分(或者可能是整个屏幕)，因为它是一个单独的Fragment，它具有自己的控制器，可以被另一个片段替换(或堆叠)，如果我想返回堆栈，则上一个Fragment将成为焦点

With such approach I don't have to worry about where my Fragment view is showing, what part of a screen (or may be, the entire screen) it is occupying as it is a separate Fragment with it's own controller that can be substituted (or stacked) with another fragments and if I want to go backstack , previous Fragment will come in focus

iOS是否有类似的产品，或者该如何实现?

Is there such an analog for iOS or how can I implement this?

推荐答案

要实现类似于片段的内容，必须在View Controller中使用Container View，并在其中填充childViewControllers.

For implementing something analogous to fragments, you must use Container View in your View Controller with childViewControllers being populated inside it.

文档:容器视图控制器

您可以在Xcode的Interface Builder的对象库中找到"Container View"元素.

You can find the 'Container View' element in the object Library of your Interface Builder in Xcode.

此外，您可以创建新的视图控制器，并通过以下代码添加该视图控制器:

Also, you can create the new view controller that you want to add it through code as follows:

Obj-C代码:

//To add child VC
- (void) displayContentController: (UIViewController*) content;
{
    [self addChildViewController:content];                 
    content.view.frame = self.containerView.bounds;
    [self.containerView addSubview:content.view];
    [content didMoveToParentViewController:self];          
}

//To remove child VC
- (void) hideContentController: (UIViewController*) content
{
    [content willMoveToParentViewController:nil];  
    [content.view removeFromSuperview];            
    [content removeFromParentViewController];      
}
