A simple demo of handling custom URL schemes with a Cocoa application.
This application registers for the scheme bnr-custom. Thus when the user opens a URL of the form bnr-custom://..., this application will be opened and the URL will be appended to the text field.
Handling a custom scheme in your application can be boiled down to three basic steps:
- Add the URL type to the Info.plist. This can be done using the Project editor in Xcode.
- Register to receive
kAEGetURLevents in-applicationDidFinishLaunching:or similar. - Handle the events in method corresponding to the selector you registered.
In this project, the latter two steps can be seen in AppDelegate.m.
These steps are documented in the Cocoa Scripting Guide, under How Cocoa Applications Handle Apple Events, although not much detail is provided on how to obtain the actual URL.
