View Hierarchies can be debugged, meaning that you can view them in a visual, 3D perspective instead of simply from the document outline. In this movie, you will see the features of the debug view hierarchy perspective and look at what options you have for viewing the layering and layouts of your applications in 3D space.
- [Voiceover] There's one more thing I want to show you…with the View Hierarchies.…If it's confusing to look at it in the Document Outline,…there's actually another way that you can look at…a View Hierarchy in iOS.…You want to run the application,…and when the application's running,…you have an option in the Debugger…to view the View Hierarchy.…So here's the app and some of that…rectangle's getting cut off on the right side,…we have our Label and we have our Button.…Now we don't want to stop the app,…we want to make sure that it's running.…
We're going to go back into Xcode,…and we get these special options on the Debugger…that apply to our view.…So this one right here is the one I want to focus on.…Debug View Hierarchy.…So this is made for solving problems in your View Hierarchy.…So when your app is running, it doesn't look like how…you want it to look, you can click this button right here,…and when we do that, it might take a minute to load up,…but you're going to see your visual layout…of your app right here.…
