Earlier this week I mentioned a nice guide on making content within your apps searchable on device.
Here’s a tutorial from Luke Parham on using iOS’s state restoration feature allowing a user to return to an app exactly the way that they left it.
State restoration is important because if your app is removed from the device’s memory then without state restoration the app will start-up all over again.
In the tutorial Luke covers the creation of a simple app, how to set up that state restoration, how to test state restoration, and how to use the UISTateRestoring protocol to make sure your app state is properly restored.
You can find the tutorial on the Ray Wenderlich blog.
