如何在Monotouch中绑定扩展方法？

Question

I'm having a hard time to define the correct bindings for an IOS static library. The include file contains some extension methods defined as:

#import <Foundation/Foundation.h>
@interface UIView(LayerEffects)

// set round corner
- (void) setCornerRadius : (CGFloat) radius;
// set inner border
- (void) setBorder : (UIColor *) color width : (CGFloat) width;
// set the shadow
// Example: [view setShadow:[UIColor blackColor] opacity:0.5 offset:CGSizeMake(1.0, 1.0) blueRadius:3.0];
- (void) setShadow : (UIColor *)color opacity:(CGFloat)opacity offset:(CGSize) offset blurRadius:(CGFloat)blurRadius;

@end

The Monotouch documentation ( Binding Class Extensions ) is not very clear how to actually handle this.

Should this also be defined as an extension C# method? Or do we have to define this in the class "LayerEffects"?

Update Following mapping does not work:

[BaseType (typeof (UIView))]
interface LayerEffects{

    [Bind ("setCornerRadius:")]
    void SetCornerRadius ([Target] UIView uiView, float width);

    [Bind ("setBorder:width")]
    void SetBorder ([Target] UIView uiView, UIColor color, float width);

    [Bind ("setShadow:opacity:offset:blurRadius")]
    void SetShadow ([Target] UIView uiView, UIColor color, float opacity, SizeF offset, float blurRadius);

}

I think you would have to define a new class to make a binding:

[BaseType(typeof(UIView))]
public interface UIViewLayerEffects
{

}

But this doesn't really help your situation.

You want to use this on any UIView right?

It might be easier to translate the code underneath into C#. These methods don't look too hard to implement. For example, I think setCornerRadius is just this:

myView.Layer.CornerRadius = 3f;
