How to assign application to all desktops (spaces) of Mac OS X Lion using Objective C?

I am trying to create an Application on Mac OS X Lion which requires application to be assigned to All Desktops (Spaces). This can be manually done by Right clicking on application's dock icon and Selecting Options > Assign To > All Desktops. But, I need to find a way to do this via Objective C. Is there a way to achieve this programmatically?

You can use method setCollectionBehavior: of NSWindow with the NSWindowCollectionBehaviorCanJoinAllSpaces bitwise flag.

It will make the window visible on all spaces.

NSUInteger collectionBehavior;

// Gets the current collection behavior of the window
collectionBehavior = [ myWindow collectionBehavior ];

// Adds the option to make the window visible on all spaces
collectionBehavior |= NSWindowCollectionBehaviorCanJoinAllSpaces;

// Sets the new collection behaviour
[ myWindow setCollectionBehavior: collectionBehavior ];

Note

This method was introduced in Mac OS X 10.6.

On Mac OS X 10.5, you'll need to use the canBeVisibleOnAllSpaces: method of NSWindow.
