Since its introduction in iOS 5, our good friend the UISplitView Controller has always had a really annoying habit: it has to be the root view controller in our apps. This means that it cannot be presented from any other view controller, nor can the split view controller present other view controllers.
This sucks because 99% of all apps probably need to present a user choice overlay at some point during the lifetime of an app. While some apps may get away with showing a Popover on iPad, many apps would be better off if we could present something like a proper form sheet as pictured in the image above. However, by Apple’s definition, that’s just not possible with the split view controller.
Or is it…?
In this screencast I’ll show you how to make it appear as if we could present another view controller over a UISplitView Controller. We’ll employ a bit of magic to create a great user experience, and it’s not really difficult either. The whole thing works on both iPhone and iPad with no extra work, and it works with apps in Slideover Mode too.
At the bottom of the article I’ll show you the code snippets to make this magic happen, together with a fully working demo project.
