iPhone屏幕锁定通知应用程序

Question

How can I be notified that the screen/phone was locked while my app is running? 如何在我的应用程序运行时通知屏幕/手机被锁定？ I want to suspend some timers related to refreshing the display in such cases. 在这种情况下，我想暂停一些与刷新显示相关的计时器。

I think your UIApplicationDelegate will receive the following message before the screen gets locked: 我认为您的UIApplicationDelegate会在屏幕锁定之前收到以下消息：

- (void)applicationWillResignActive:(UIApplication *)application

here the link to the documentation: http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/applicationWillResignActive : 这里是文档的链接： http ： //developer.apple.com/iphone/library/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/applicationWillResignActive ：
