当有人打电话/发短信给你时暂停游戏

Question

我想在我的应用程序上实现此功能,但我似乎无法弄清楚如何使用这行代码.

- (void)applicationWillResignActive:(UIApplication *)application {
 //our app is going to loose focus since there is an incoming call
 [self pauseGame];
}

- (void)applicationDidBecomeActive:(UIApplication *)application{
 //the user declined the call and is returning to our app
 [self resumeGame];
}

我已经读过这个必须放在appdelegates但我似乎无法弄清楚当游戏当前在viewcontroller中时我怎么能调用我的暂停动作.

谢谢.

您可以将它们发送给您的视图控制器,而不是将消息发送给自己(这是应用程序委托).

例如,如果您的应用程序委托具有名为"gameViewController"的主游戏视图控制器的属性(其中实现了暂停和恢复的方法):

- (void)applicationWillResignActive:(UIApplication *)application {
    // our app is going to loose focus since there is an incoming call
    [self.gameViewController pauseGame];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // the user declined the call and is returning to our app
    [self.gameViewController resumeGame];
}
