iphone - 当有人给您打电话/发短信时暂停游戏

Question

我想在我的应用程序上实现这个功能，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];
}

我读到这必须放在 appdelegates 中，但我似乎无法弄清楚当游戏当前在 viewcontroller 中时如何调用我的暂停操作。

谢谢。

您可以将消息发送给您的 View Controller ，而不是将消息发送给自己(应用委托(delegate))。

例如，如果您的应用委托(delegate)有一个名为“gameViewController”的主游戏 View Controller 属性(其中实现了暂停和恢复方法):

- (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];
}
