检测来电

简而言之-不,您无法确定应用程序中是否有来电或其他类型的中断。

我发现了这篇关于处理来电、终止恢复和保持状态的文章。

它可能会帮助你……

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

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

(void)applicationWillTerminate:(UIApplication*)application{
        //the user answered the call (or quit the app) so save the
        //game as we are shutting down
        [self saveGameState];
}

我知道这个问题很古老,但是如果有人像我一样回答这个问题,会有一个音频会话代表来检测音频是否会被中断(主要是通过电话)。

对于任何播放音频的应用程序,此方法都适用于检测传入的iPhone呼叫。
