Tag: Custom URI URL Protocol

Have you ever wondered how the magic behind the “mailto://” or other similar Uniform Resource Identifiers (URI) work? Whether from the web browser URL field or from Xojo via the ShowURL function, when URIs are executed the registered app opens showing the passed parameters (for example, in the Mail app for the ‘To’, ‘Subject’ and ‘Body’ fields).

Implementing this kind of behavior in your OS X apps is not rocket science! Follow these simple steps in order to register a custom URI from your app.
