为什么在iPhone 6 Plus上未调用splitViewController:collapseSecondaryViewController:ontoPrimaryViewController :? [英] Why splitViewController:collapseSecondaryViewController:ontoPrimaryViewController: is not called on iPhone 6 Plus?

问题描述

我在我的应用程序中为iPhone和iPad都实现了UISplitViewController的子类.当我将设备从Landscape旋转到Portrait方向时，将调用标题中提到的方法.除非我在iPhone 6 Plus上运行该应用程序，否则它确实非常不错.为什么不在那里调用此方法?

I implemented subclass of UISplitViewController in my app for both: iPhone and iPad. Method mentioned in title is called when I rotate device from Landscape to Portrait orientation. It works really nice unless I run the app on iPhone 6 Plus. Why this method is not called there?

如何使此方法起作用?

当我在iPhone 6 Plus上启动应用程序时，两个方向的一切都很好.但是问题是当我将iPhone 6 Plus从Landscape旋转到Portrait时.我的导航控制器无法正常工作.

When I start the app on iPhone 6 Plus everything is fine in both orientations. But the problem is when I rotate iPhone 6 Plus from Landscape to Portrait. My navigation controller is not gonna work as it is expected.

这是我的意思:

iPhone 5s纵向

当我选择位置时，iPhone 5s Portrait

具有选定位置的iPhone 5s横向

当我从横向旋转到纵向时，iPhone 5s

iPhone 6 Plus Portrait

当我选择位置时，iPhone 6 Plus Portrait

具有选定位置的iPhone 6 Plus Landscape

iPhone 6 Plus，当我从横向"旋转到纵向"时 this is a problem，因为未调用我的方法splitViewController:collapseSecondaryViewController:ontoPrimaryViewController:.当时的UINavigationController无法正常工作.当我选择位置时，什么也没发生.

iPhone 6 Plus when I rotate from Landscape to Portrait this is a problem because my method splitViewController:collapseSecondaryViewController:ontoPrimaryViewController: is not called. UINavigationController at that time is not working. When I select location nothing happens.

class PBOSplitViewController: UISplitViewController, UISplitViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        preferredDisplayMode = UISplitViewControllerDisplayMode.AllVisible
        delegate = self
    }

    func splitViewController(splitViewController: UISplitViewController, collapseSecondaryViewController secondaryViewController: UIViewController!, ontoPrimaryViewController primaryViewController: UIViewController!) -> Bool {
        return false
    }
}

我在Storyboard中设置了SplitViewController.

I setup my SplitViewController in Storyboard.

推荐答案

iPhone 6+的屏幕更大，并且在某些方面被视为iPad. iPhone 6+上的拆分视图控制器将尝试显示与iPad相似的主窗格和详细窗格，除非该应用程序处于缩放显示模式".

iPhone 6+ has a larger screen and in some ways is treated like an iPad. A split view controller on an iPhone 6+ will try to display both master and detail panes similarly as on an iPad, unless the application is in "Zoomed Display Mode".
