[MonoTouch] Problem with UISegmentedControl on iPad

[Craig Dunn]

What iOS version is your iPad running?
ApportionsSegmentWidthsByContent is iOS5 only. Using that property seems to
work on my iPad with iOS5.1 installed...

You could try something like this to avoid 'unknown selector' errors

if (*yourSegmentedControl*.RespondsToSelector(new
MonoTouch.ObjCRuntime.Selector("apportionsSegmentWidthsByContent"))) {

mapTypes.ApportionsSegmentWidthsByContent = true;

}


Roy - i think obj-c "properties" follow that standard where the getter has
the 'name' of the property and the setter has the 'set' prefix...
