Description Mark Daniel 2013-02-07 05:10:23 UTC
There is a native method on UIImage called


But the binding for UIImage only has 

UIImage CreateResizableImage (UIEdgeInsets capInsets)

I was expecting an overload 

UIImage CreateResizableImage (UIEdgeInsets capInsets, UIImageResizingMode resizingMode)

But there is none. 

There is a constructor for (UIEdgeInsets capInsets, UIImageResizingMode resizingMode) but it's no use because UIImage is immutable and there is no way to get data into it.

There was a bug in the CreateResizableImage binding, you can for now do:

(UIImage) Runtime.GetNSObject (someImage.CreateResizableImage (capInsets, resizingMode))

For now, the next version will fix the return value from IntPtr to UIImage.

The workaround wont work, I was looking at our local fix.
Comment 3 Mark Daniel 2013-02-12 05:22:50 UTC
The work around I am using is

  /// <summary>
    /// Extensions to the UIImage class
    /// </summary>
    /// <remarks>Adds a method that exists in native but is missing from the MT bindings</remarks>
    public static class UIImageExtensions

        /// <summary>
        /// Creates a new resizeable image from this one. Allow you to specify the fixed regions and the resizing mode.
        /// </summary>
        /// <returns>The resizable image.</returns>
        /// <param name="image">Image.</param>
        /// <param name="capInsets">Cap insets.</param>
        /// <param name="resizingMode">Resizing mode.</param>
        public static UIImage CreateResizableImage(this UIImage image, UIEdgeInsets capInsets, UIImageResizingMode resizingMode)
            UIImage result;

            using (new NSAutoreleasePool ())

                if (image.GetType() == typeof(UIImage))
                    result = (UIImage)Runtime.GetNSObject
                         IntPtr_objc_msgSend_UIEdgeInsets_int (image.Handle, 
                                                              new Selector("resizableImageWithCapInsets:resizingMode:").Handle, 
                    result = (UIImage)Runtime.GetNSObject
                        (Messaging.IntPtr_objc_msgSend_UIEdgeInsets_int (image.SuperHandle,
                                                                         new Selector("resizableImageWithCapInsets:resizingMode:").Handle, capInsets,
            return result;
