SubName: autoresizingMask
Description: Ios doesn't have the FillParent option that Android does, instead it has a more flexible approach using a mask:
Documentation is here: https://developer.apple.com/library/ios/documentation/uikit/reference/UIView_Class/index.html#//apple_ref/occ/instp/UIView/autoresizingMask
The mask is a series of bits that defines how a subviews size should be adjusted when the parent size changes.
Possible options are:
UIViewAutoresizingNone = 0,
UIViewAutoresizingFlexibleLeftMargin = 1 << 0,
UIViewAutoresizingFlexibleWidth = 1 << 1,
UIViewAutoresizingFlexibleRightMargin = 1 << 2,
UIViewAutoresizingFlexibleTopMargin = 1 << 3,
UIViewAutoresizingFlexibleHeight = 1 << 4,
UIViewAutoresizingFlexibleBottomMargin = 1 << 5
We can access this using NativeObject:
Where 16 is equivelent to 1<<4 (Bit.ShiftLeft(1,4))
The code above will change the height of the view when the parents height changes. The change is relative, so if the view is set at 50% of the parents height, it will remain so.
To change height and width the code would be:
This function is contained in the UIView class so should work on any View.
