在 ios8 中使用 appdelegate 暂停 spritekit 游戏 [英] pausing spritekit game using appdelegate in ios8

问题描述

我的游戏中有一个暂停菜单，当我按下主页按钮时，我想切换该菜单.当我在我的游戏中时它可以工作，但是当我按下主页按钮时菜单出现，但游戏不会暂停.

当我重新启动应用程序时，菜单仍然存在，但游戏自行取消暂停.当您离开并进入应用程序时，似乎 spritekit 会自动暂停并自行重新启动游戏.当我在应用程序中时，我可以完全控制它.但是当我退出/进入应用程序时，它的行为就像它喜欢的那样.

有什么建议吗?

func applicationWillResignActive(application: UIApplication!) {//获取根视图控制器//切换我的暂停菜单方法.暂停菜单集 skview.paused = true}

解决方案

发送一个 NSNotification 到 GameSceneViewController 来暂停 SKScene:>

应用程序委托:

- (void)applicationWillResignActive:(UIApplication *)application{//暂停精灵套件场景[[NSNotificationCenter defaultCenter] postNotificationName:@"PauseGameScene" object:self];}

GameSceneViewController:

- (void)viewDidLoad {[[NSNotificationCenter defaultCenter] addObserver:self选择器:@选择器(暂停游戏场景)名称:@"PauseGameScene"对象:无]；}- (void)pauseGameScene {如果(self.skView.scene){self.skView.paused = self.skView.scene.paused = YES;}}

I have a pause menu in my game that I want to toggle when the i hit my home button. it works when I'm within my game, however when I hit my home button the menu comes up, but the game will not pause.

when i restart the app, the menu is still there, but the game un-pauses itself. It seems like spritekit automatically pauses and restarts the game on its own when you leave and enter the app. When I'm within the app I have full control over it. But when I'm exiting/entering the app it behaves how it likes.

Any suggestions?

func applicationWillResignActive(application: UIApplication!) {
    // get the root viewcontroller
    // toggle my pausemenu method.  pause menu sets skview.paused = true
}

解决方案

Send an NSNotification to GameSceneViewController to pause the SKScene:

AppDelegate:

- (void)applicationWillResignActive:(UIApplication *)application
{    
    // Pause sprite kit scene
    [[NSNotificationCenter defaultCenter] postNotificationName:@"PauseGameScene" object:self];
}

GameSceneViewController:

- (void)viewDidLoad {
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(pauseGameScene)
                                                 name:@"PauseGameScene"
                                               object:nil];
}

- (void)pauseGameScene {
    if (self.skView.scene) {
        self.skView.paused = self.skView.scene.paused = YES;
    }
}
