AMWorkflowController class lets you manage an Automator workflow in your application. You use the
AMWorkflow class to instantiate a workflow and an instance of
AMWorkflowView to display it.
A controller can run and stop a workflow and obtain information about its state. The controller’s delegate can receive messages as the workflow is executed and its actions are run.
You can load and run a workflow with minimal overhead by using the
AMWorkflow class method
runWorkflowAtURL:withInput:error:. When you use
AMWorkflowController, you get more control of the process, but there’s more work, as you must create and initialize both the workflow and the workflow controller objects.
A workflow is run in a separate process so that any actions it contains are executed in a separate memory space. That helps to insulate your application from crashes, memory leaks, or exceptions that might occur from running the actions in a workflow.
