uipopovercontroller

问题 How can "perform selector" to the parentviewcontroller of the uipopovercontroller? I have uipopovercontroller lanuched from uiviewcontroller, and this uipopovercontroller includes other uiviewcontroller. I can't seem to reach the parent view controller from either the popover or the "internal" view controller. I hope i'm being clear... BTW - parentViewcontroller doesn't work...

问题 What I meant is, When we use a UISplitViewController project In portrait mode, whole window will be covered by the view and a popoverController will be presented to navigate to other views.

问题 I have an iPad application which implements the UISplitViewController. As usual I'm using the popover button to show the root view when the device is in portrait mode. It's seems to be ok at time of launch, but if I turn the device to landscape, then back to portrait, the table in the popover, will have an additional blank row at top, so that I have to scroll down to see the others...

问题 In a universal binary iPhone/iPad app of mine, users are able to adjust preferences in a view controller that's presented modally.

问题 I'm trying to remove the dimming view behind a popover presented using UIPopoverPresentationController.

I've tracked the dimming view to a "_UIMirrorNinePatchView" using the view hierarchy inspector, but there's no good way of removing it short of crawling through the subviews of UIWindow and manually removing this view from its superview. This approach is flawed as it
