Question

I’ve successfully added printing capabilities to an iPad application that makes use of the UIPrintInteractionController class. Things work well, and a standard document is printed.

There are a couple BOOL properties that can be defined for a print job in my application, however. (Turning on certain features, adding additional layout schemes, etc.)

How can these options be presented/modified by the user using the UIPrintInteractionController? The perfect solution would be to add a couple switch table view cells to the UITableView that is presented in that controller, but this doesn’t seem to be allowed by the API.

Edit: This is the view I’m referring to:

It looks like the best bet (so far) is to assign a delegate to the UIPrintInteractionController, and have that delegate implement the method:

- (UIViewController *)printInteractionControllerParentViewController:(UIPrintInteractionController *)printInteractionController

If the delegate returns an instance of a UINavigationController, then instead of being presented modally, it can be pushed from a UITableViewController subclass that provides a list of options.

From the UIPrintInteractionControllerDelegate class reference:

UIKit can push the returned view controller onto the stack if its
parent is a navigation controller or present it modally if it isn’t.
