これが私が最終的に構築したものです。あまり満足していないので、今まで投稿していませんでした。同じクラスのコントローラーを表示する 2 つのセグエはサポートされず、ポップオーバーのソース rect とソース ビューを自分で追跡する必要があります。しかし、おそらくそれは他の誰かにとって良い出発点になるでしょう.
PushPopoverSegue.swift
import UIKit

var sourceBarButtonItem: UIBarButtonItem!
var permittedArrowDirections: UIPopoverArrowDirection = .Any
override func perform() {
assert( self.sourceViewController.navigationController != nil )
assert( self.sourceBarButtonItem != nil )
if self.sourceViewController.traitCollection.horizontalSizeClass == .Compact {
self.sourceViewController.navigationController!.pushViewController(self.destinationViewController, animated: true)
}
else {
let navigationController = UINavigationController(rootViewController: self.destinationViewController)
let popover = UIPopoverController(contentViewController: navigationController)
popover.presentPopoverFromBarButtonItem(self.sourceBarButtonItem, permittedArrowDirections: self.permittedArrowDirections, animated: true)
}
}
}

使用例
インターフェイスビルダーでセグエを作成し、その「Kind」を Custom に、「Class」を に設定しPushPopoverSegue
ます。
ViewController.m
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
((PushPopoverSegue*) segue).sourceView = /* source view */;
((PushPopoverSegue*) segue).sourceRect = /* source rect */;
}
-(void) willTransitionToTraitCollection:(UITraitCollection *)newCollection withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
if ( newCollection.horizontalSizeClass == UIUserInterfaceSizeClassUnspecified )
return;
[self transitionPushPopoversToHorizontalSizeClass:newCollection.horizontalSizeClass withMapping:@{
@"MyDestinationViewController": @[ /* source view */,
[NSValue valueWithCGRect:/* source rect*/] ]
}];
}
