问题描述
我已经阅读了我能找到的关于这个主题的所有内容，但仍然无法弄清楚我的问题.我尝试在 appdelegate 的每个区域暂停我的游戏
I've read everything I could find on this topic and still cant figure out my issue. I have tried pausing my game in every area of appdelegate
func applicationWillResignActive(application: UIApplication!) {
NSNotificationCenter.defaultCenter().postNotificationName("pauseGameScene", object: self)
}
func applicationDidEnterBackground(application: UIApplication!) {
NSNotificationCenter.defaultCenter().postNotificationName("pauseGameScene", object: self)
}
func applicationWillEnterForeground(application: UIApplication!) {
NSNotificationCenter.defaultCenter().postNotificationName("pauseGameScene", object: self)
}
func applicationDidBecomeActive(application: UIApplication!) {
NSNotificationCenter.defaultCenter().postNotificationName("pauseGameScene", object: self)
}
在我的控制器中:
override func viewDidLoad() {
NSNotificationCenter.defaultCenter().addObserver(self, selector: "pauseGame:", name: "pauseGameScene", object: nil)
}
func pauseGame(){
self.skView.paused = true
self.skView.scene!.paused = true
}
我知道 pauseGame 有效，因为如果我在场景中使用按钮切换它，它将停止游戏.即使我在将它们加载到控制器后直接暂停我的 skview 和场景.. 游戏在启动时也不会暂停.当我在游戏中时，很容易暂停游戏.但出于某种原因，每当我退出并恢复应用程序时，游戏都会自行取消暂停.
i know pauseGame works because if i toggle it with a button in my scene, it will stop the game. Even if I pause my skview and scene directly after they are loaded in the controller.. the game will not be paused on launch. It's easy to pause the game when I'm in-game. but for some reason whenever i exit and resume the app, the game will un-pause itself.
我注意到如果我变得 hacky 并使用某种延迟.. 我可以让它工作.但显然这很愚蠢..我只需要知道游戏在哪里取消暂停！
i notice if i get hacky and use some kind of delay.. i can get it to work. but obviously this is very stupid.. i just need to know where the game is unpausing itself!
func delay(delay:Double, closure:()->()) {
dispatch_after(
dispatch_time(
DISPATCH_TIME_NOW,
Int64(delay * Double(NSEC_PER_SEC))
),
dispatch_get_main_queue(), closure)
}
func pauseGame(sender: UIButton!){
delay(2) {
println("blah")
self.skView.paused = true
self.skView.scene!.paused = true
}
}
推荐答案
这是一种让视图在从后台模式返回后保持暂停的方法.
Here's a way to keep the view paused after returning from background mode.
Xcode 7(Xcode 8 说明见下文)
Xcode 7 (see below for Xcode 8 instructions)
在故事板中，
1) 将视图的类更改为 MyView
1) Change the class of the view to MyView
在视图控制器中，
2) 使用名为 stayPaused 的布尔值定义一个 SKView 子类
2) Define an SKView subclass with a boolean named stayPaused
class MyView: SKView {
var stayPaused = false
override var paused: Bool {
get {
return super.paused
}
set {
if (!stayPaused) {
super.paused = newValue
}
stayPaused = false
}
}
func setStayPaused() {
if (super.paused) {
self.stayPaused = true
}
}
}
3) 将视图定义为 MyView
3) Define the view as MyView
4) 添加通知器来设置stayPaused 标志
4) Add a notifier to set the stayPaused flag
class GameViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {
// Configure the view.
let skView = self.view as MyView
NSNotificationCenter.defaultCenter().addObserver(skView, selector:Selector("setStayPaused"), name: "stayPausedNotification", object: nil)
在应用代理中，
5) 在应用激活时发布通知以设置保持暂停标志
5) Post a notification to set the stay paused flag when the app becomes active
func applicationDidBecomeActive(application: UIApplication) {
NSNotificationCenter.defaultCenter().postNotificationName("stayPausedNotification", object:nil)
}
Xcode 8

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "stayPausedNotification"), object: nil)
}
