[MonoTouch] Problem with UISegmentedControl on iPad

[Dean Cleaver]

Am trying to set the UISegmentedControl to ApportionsSegmentWidthsByContent = true and it crashes on the iPad - doesn't crash in the simulator (iPhone) nor on my iPhone devices. Any ideas why the difference?

MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: -[UISegmentedControl setApportionsSegmentWidthsByContent:]: unrecognized selector sent to instance 0x868fc80
