我正在尝试使用applicationDidBecomeActive方法（和类似的方法） - 我可以在ObjC中找到大量示例，但在Monotouch中没有。 在AppDelegate和UIViewController中尝试了覆盖，但编译器找不到合适的方法来覆盖。那么，我该如何使用它呢？ 我想使用它（与计时器和IdleTimerDisabled一起使用）来阻止设备比平时更长时间地进入睡眠状态（这是一个秒表型应用程序）。也许我走错了路。

在继承自UIApplicationDelegate的应用委托中，您可以覆盖以下内容：
/// <summary>
/// Gets called by iOS if the app is started from scratch and is not resumed from background.
/// We have 17 seconds to leave this methos before iOS will kill the app.
/// </summary>
public override bool FinishedLaunching ( UIApplication application, NSDictionary launchOptions )
/// <summary>
/// Called if the app comes back from background or gets started. Triggered after FinishedLaunching().
/// </summary>
public override void OnActivated ( UIApplication application )
/// <summary>
/// Called if the application gets pushed to the background because the user hits the home button.
/// </summary>
public override void DidEnterBackground ( UIApplication application )
/// <summary>
/// Gets called if the app is resumed from background but NOT if the app starts first time.
/// </summary>
public override void WillEnterForeground ( UIApplication application )
