我可以在我的应用程序中抑制系统警报吗？

当系统警报弹出时，我的应用程序是否可以“接管”？我的应用程序禁用了空闲计时器，但是当弹出系统警报时，警报似乎正在启用计时器。对此我能做什么？

您是否可以挂钩当您的应用程序进入和退出后台时调用的方法之一？你说，其中之一？

- (void)applicationWillResignActive:(UIApplication *)application {
NSLog(@"applicationWillResignActive");
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
NSLog(@"applicationDidEnterBackground");
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
NSLog(@"applicationWillEnterForeground");
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
NSLog(@"applicationDidBecomeActive");
}

我敢打赌，当这种情况发生时，其中一个会被叫到。当您的应用程序重新获得焦点时，您可以禁用空闲计时器。

编辑：在重新阅读问题时，看起来您正在寻求抑制警报（即不让它们发生）。呵呵，我主要关注你问题的后半部分。

Would it be possible for you to hook into one of the methods that gets called when your app goes in and out of the background? Say, one of these?

- (void)applicationWillResignActive:(UIApplication *)application {
NSLog(@"applicationWillResignActive");
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
NSLog(@"applicationDidEnterBackground");
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
NSLog(@"applicationWillEnterForeground");
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
NSLog(@"applicationDidBecomeActive");
}

I bet one of those gets called when that happens. You can probably disable the idle timer when your app gets the focus back.

EDIT: On re-reading the question, it looks like you're looking to suppress the alerts (i.e., not let them happen). Heh, I focused on the latter half of your question.
