getting values from NSTextField in objective c and xcode

How can I continuously get data from an NSTextField and do this in the开发者_如何学C background? I'm doing this because I'm using a quartz composer plugin to get posted values in an NSTextField. This is within the same app.

Any ideas??

I'm not sure what you mean by "continuously", but the controlTextDidChange: delegate method will tell you when the text changes.
