应用没有被杀死 有消息的时候 本地通知怎么操作？

demo MainViewController中didReceiveMessage回调，你看下。
-(void)didReceiveMessage:(EMMessage *)message

{

    BOOL needShowNotification = (message.messageType != eMessageTypeChat) ? [self needShowNotification:message.conversationChatter] : YES;

    if (needShowNotification) {

#if !TARGET_IPHONE_SIMULATOR

        

        BOOL isAppActivity = [[UIApplication sharedApplication] applicationState] == UIApplicationStateActive;

        if (!isAppActivity) {

            [self showNotificationWithMessage:message];

        }else {

            [self playSoundAndVibration];

        }

#endif

    }

}
