什么是正确的方法，使用“init”或“didmove”？

Language: Swift 3.0 --- IDE : Xcode 8.0 beta 2 --- Project : iOS Game (SpriteKit)

语言：Swift 3.0 --- IDE：Xcode 8.0 beta 2 ---项目：iOS游戏（SpriteKit）

I create a game for iOS and i know Apple is really strict with their rules to accept the app/game. So i want to know which is the correct way to setup a game.

我为iOS创建了一款游戏，我知道Apple对接受应用/游戏的规则非常严格。所以我想知道哪种是正确的游戏设置方式。

I learned from google to create a new SpriteKit Project and do the following setup :

我从谷歌学到了创建一个新的SpriteKit项目并执行以下设置：

In GameViewController.swift clear viewDidLoad() and add all this :

在GameViewController.swift中清除viewDidLoad（）并添加所有这些：

override func viewDidLoad() {
    super.viewDidLoad()
    let skView = self.view as! SKView

    let scene = GameScene(size: skView.bounds.size)
    scene.scaleMode = .aspectFit

    skView.presentScene(scene)
}

In GameScene.swift delete everything and leave this code :

在GameScene.swift中删除所有内容并保留此代码：

import SpriteKit

class GameScene: SKScene {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override init(size: CGSize) {
        super.init(size: size)
        // add all the code of the game here...
    }

}

and develop my game inside override init

并在覆盖init中开发我的游戏

But I think thats actually wrong to start the game with init. And that the right way is to use the didMove() method. So should the code be written inside here? :

但我认为用init启动游戏实际上是错误的。而正确的方法是使用didMove（）方法。那么代码应该写在这里吗？ ：

override func didMove(to view: SKView) {
    <#code#>
}

Does anyone know which one is the correct way? And why? Also if its wrong the way i do it, can you explain me how to use didMove method?

有谁知道哪一个是正确的方法？为什么？如果我的方式错了，你能解释一下如何使用didMove方法吗？

Don't know if this is a silly question just bothered me that using init is wrong and wanted to ask if someone knows more about this.

不知道这是一个愚蠢的问题，只是让我感到困扰，使用init是错误的，并想问一下是否有人知道更多。

Overriding the SKScene init

You can override the initializers of SKScene like described by @Knight0fDragon

您可以覆盖SKScene的初始化程序，如@ Knight0fDragon所述

class GameScene : SKScene {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setup()             
    }

    override init() {
        super.init()
        setup()
    }

    override init(size: CGSize) {
        super.init(size: size)
        setup()
    }

    func setup()
    {
        // PUT YOUR CODE HERE

    }
}

Or you can use the didMove(to:)

class GameScene: SKScene {
    override func didMove(to view: SKView) {
        super.didMove(to: view)
        // PUT YOUR CODE HERE <-----
    }
}

The init is called only when the scene is initialised. The didMove is called when the scene is presented into the view.

仅在初始化场景时调用init。当场景呈现在视图中时，将调用didMove。
