我有问题,

我用monotouch 5.2.8来编程iOS 5.1。

但自IOS 5.1更新我的iPad配置UISplitViewController,以便停靠 左侧而不是呈现为一个popover。

它适用于iOS 5.0,但在5.1中我收到了这个问题。

这是我的UISPLITVIEWController的源代码:

splitViewController = new UISplitViewController ();
splitViewController.WeakDelegate = detailViewController;                
splitViewController.ViewControllers = new UIViewController[] {
     navigationController,
     detailViewController                   
};
.

有帮助吗?

解决方案

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.

其他提示

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.
