Available in Mac OS X v10.0 and later.


- aSelector (IntPtr)
- A selector that identifies the method to invoke. The method should not have a significant return value and should take a single argument of type id, or no arguments.
- anArgument (Id)
- The argument to pass to the method when it is invoked. Pass nil if the method does not take an argument.
- delay (Double)
- The minimum time before which the message is sent. Specifying a delay of 0 does not necessarily cause the selector to be performed immediately. The selector is still queued on the thread’s run loop and performed as soon as possible.

- Available in Monobjc Bridge: 10.6 (For Mac OS X 10.6 and later), 10.5 (For Mac OS X 10.5 and later)
