Answer 1

I think you need to ovverride the following in your delegate:

- (UIViewController *)primaryViewControllerForCollapsingSplitViewController:(UISplitViewController *)splitViewController

When this is called, return the controller you want to be shown. According to the docs you should also implement the other direction:

- (UIViewController *)primaryViewControllerForExpandingSplitViewController:(UISplitViewController *)splitViewController

See: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UISplitViewControllerDelegate_protocol/index.html#//apple_ref/occ/intfm/UISplitViewControllerDelegate/primaryViewControllerForCollapsingSplitViewController :

Answer 2

在文档中，您可以设置preferredDisplayMode

self.splitViewController.preferredDisplayMode == UISplitViewControllerDisplayModePrimaryOverlay
