Determine when UIImageView has finished loading an image

Hi Everyone,

I'm hoping this isn't a complete noob question, but is there a way I can receive a notification when an UIImageView has completed loading an image?

I'm using MvvmCross to bind a string URL to the ImageUrl property of the MvxImageView so I'm not sure if this is complicating things because MvvmCross takes care of the actual downloading/caching of the image behind the scenes.

Thanks in advance for any help! Ryan
