iOS 5.1 swipe gesture hijacked by UISplitViewController - how to avoid?

问题 A new behavior in iOS 5.1 related to UISplitViewController apps seems to be intercepting UISlider motion with undesired results. This might also apply to UISegmented Controls and any other control surface that handles left-to-right gestures. With a UISplitView in Portrait orientation, the Master view is normally hidden. Starting in iOS 5.1 a right swipe on screen brings up the Master View on the left side of the device. The problem is, sliding the thumb of my UISlider control is

Looks like iOS 5.1 has broken the standard URL encoding for navigating a user to a Preference. For example: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]]; Works in iOS 5.0 but not in iOS 5.1 (both device and simulator). Has anyone found a way to replicate this functionality in iOS 5.1? JoePasq No I don’t know a way to replicate this functionality. But what you can do is file a Radar requesting the restoration. Here is a radar requesting that the schemes be documented in the first place. David Barnard has confirmed that iOS 5.1 breaks the settings apps
