ios - 进入Suspended状态后会调用AppDelegate的什么方法？

Question

我的应用程序进入后台，如果我再次打开，它会显示我离开它的同一页面。

虽然，如果 iOS 将应用程序置于暂停状态，但它仍在内存中。如果我回来，将调用哪些 AppDelegate 方法。

实际上我的目的是将相同的屏幕从暂停状态恢复到应用程序，如果它没有被终止的话。

最后，如果应用从暂停状态返回，将调用 didFinishLaunchWithOptions 吗？

谢谢..

作为Apple Documentation州，

• application:willFinishLaunchingWithOptions:—This method is your app’s first chance to execute code at launch time.

• application:didFinishLaunchingWithOptions:—This method allows you to perform any final initialization before your app is displayed to the user.

• applicationDidBecomeActive:—Lets your app know that it is about to become the foreground app. Use this method for any last minute
  preparation.

• applicationWillResignActive:—Lets you know that your app is transitioning away from being the foreground app. Use this method to
  put your app into a quiescent state.

• applicationDidEnterBackground:—Lets you know that your app is now running in the background and may be suspended at any time.

• applicationWillEnterForeground:—Lets you know that your app is moving out of the background and back into the foreground, but that it is not yet active.

• applicationWillTerminate:—Lets you know that your app is being terminated. This method is not called if your app is suspended.

所以 applicationWillEnterForeground 和 applicationWillResignActive 将被调用!
