当应用程序在iPhone中进入睡眠模式时，我们可以锁定应用程序吗？ [英] Can we lock the app while app goes to sleep mode in IPhone?

问题描述

我正在使用包含锁定选项的应用程序。我的应用程序以密码屏幕启动。如果我输入正确的代码，则导航到下一个屏幕。如果我长时间不使用该应用程序，它将进入睡眠模式。当用户现在想要运行应用程序，应该出现密码屏幕并且用户必须再次输入代码。这可能吗？有没有这方面的教程？如果你已经完成它，请不要介意发布相关代码。谢谢你提前。

推荐答案

是的，有可能。您必须在Application Delegate中以名为 applicationDidBecomeActive 的方法打开屏幕。每次从后台打开应用程序时都会调用此方法。

Yes ofcourse it is possible. You must open the screen in a method called applicationDidBecomeActive in your Application Delegate. This method is called every time the application is opened from background.

因此，无论何时用户启动已经运行的应用程序，都会调用此方法，您可以先显示此方法密码屏幕，然后是相应的屏幕。

So whenever the user starts the already running app, this method will be called and from this you can first show the Password screen, and after that the respective screen.
