Question

我创建了一个游戏...但是当设备关闭时我需要让游戏暂停...当设备关闭时是否有类似viewdidload的动作？三江源

Answer 1

如果“关闭”是指“睡眠”，则有两种方式：

在您的app delegate中实现这些：

- (void)applicationWillResignActive:(UIApplication *)application
{
   // do sleep stuff
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
   // do wake stuff
}

或注册这些通知：

[[NSNotificationCenter defaultCenter] addObserver:thingThatCares
                                         selector:@selector(whatToDoOnSleep:)
                                             name:UIApplicationWillResignActiveNotification
                                           object:[UIApplication sharedApplication]];
[[NSNotificationCenter defaultCenter] addObserver:thingThatCares
                                         selector:@selector(whatToDoOnWake:)
                                             name:UIApplicationDidBecomeActiveNotification
                                           object:[UIApplication sharedApplication]];

我会使用app Delegate方法：

- (void)applicationWillTerminate:(UIApplication *)application

暂停游戏。
