In my application all images, local HTML pages etc. are marked as Build action

  • 0

In my application all images, local HTML pages etc. are marked as “Build action Content”.
I have just realized that there is also “Resource”.

Which one should I use for images and which one for HTML pages to display in a UIWebView?

Currently I use images like this:

this.oImgLoginLogo.Image = UIImage.FromFile ( "Data/Images/ball.png" );

But in Monotouch.Dialog I see this line:

static UIImage arrow = Util.FromResource (null, "arrow.png");

But arrow.png is also marked as “content”…?

Puzzled.

What are the disdavantages/advantages of each option?

    In the .NET world, the difference is that during the build process a file marked as Content gets copied to the output folder, while a Resource file becomes part of the DLL itself.

    AFAIK, MonoTouch doesn’t includes resources into the build, because that doesn’t exist in iOS, so that’s why you always use Content. A final step then zips the directory with the executable and the content files into the .app file, which is how iOS expects it. The same thing is valid for MonoDroid.

    The difference between MonoTouch and MonoDroid in the API exist because the idea of those frameworks is to translate, almost one-to-one, the APIs available in those platforms, instead of creating one interface that supports all platforms equally.
