UisplitViewController Problemi con iOS 5.1

Domanda
Ho un problema,
Sto programmando con Monotouch 5.2.8 per iOS 5.1.
Ma dal momento che iOS 5.1 Aggiornamento Il mio iPad configura la configurazione UISPlitViewController in modo che sia attraccato sul lato sinistro invece di presentato come avover.
funziona con iOS 5.0 ma in 5.1 ho avuto questo problema.
Ecco il codice sorgente per il mio UisplitViewController:
splitViewController = new UISplitViewController ();
splitViewController.WeakDelegate = detailViewController;
splitViewController.ViewControllers = new UIViewController[] {
navigationController,
detailViewController
};
. Soluzione
From Apple's iOS 5.1 SDK release notes:
In 5.1 the UISplitViewController class adopts the sliding presentation style when presenting the left view (previously only seen in Mail). This style is used when presentation is initiated either by the existing bar button item provided by the delegate methods or by a swipe gesture within the right view. No additional API adoption is required to obtain this behavior, and all existing API, including that of the UIPopoverController instance provided by the delegate, will continue to work as before. If the gesture cannot be supported in your app, set the presentsWithGesture property of your split view controller to NO to disable the gesture. However, disabling the gesture is discouraged because its use preserves a consistent user experience across all applications.
Here (login required).
UPDATE:
From what I understand on the above, we can kiss the automatic popover appearance of the master controller goodbye in iOS 5.1.
The only way I see is possible to keep the "old" appearance, is by implementing our own UIPopoverController
and taking advantage of the ShouldHideViewController
delegate method. Thankfully with MonoTouch, we have that method available as a property in the UISplitViewController
class, making things a bit simpler.
I do get a strange behavior though. With iOS SDK 5.1 on my Mac and iOS 5.1 on my iPad; on the device, I get the "sliding" appearance, while on the simulator I get the "old", popover appearance. This is with MonoTouch 5.2.4, which is the latest stable version. Also, it does not contain a PresentsWithGesture
property. I tried setting its value to false through MonoTouch.ObjCRuntime messaging, but no luck. The selector keeps returning true. So I cannot deactivate the swipe gesture.
Even tried creating my own UIPopoverController
and assigning it as the master in the split controller to see what happens. Doesn't work because UIPopoverController
is not a UIViewController
...
Some useful info in this question, for ObjC.

Turns out you can disable the presentsWithGesture
in the application delegate, but once the view controllers have been presented, there is no changing it.
I needed to disable the appearance of the left view controller during a login process, but turns out I can't enable it later.
