Set the value of a textField in Objective-C

I've got an NSTextField called resultsView that I'd like to populate with the string graphical_availability.

I've tried the following:

[resultsView setValue:graphical_availability];

but keep getting an error during runtime:

2012-08-13 08:39:08.468 App-Name[75231:6003] -[NSTextField setValue:]: unrecognized selector sent to instance 0x100509730
2012-08-13 08:39:08.470 App-Name[75231:6003] An uncaught exception was raised
2012-08-13 08:39:08.470 App-Name[75231:6003] -[NSTextField setValue:]: unrecognized selector sent to instance 0x100509730

So, obviously setValue isn't recognized as a method on the NSTextField class that I'm using. I'm new to Objective-C (obviously) and have had trouble finding it on Apple's docs.

How can I set the value of this textField?

Thank you!

Don't forget the underscore to call the setter:

[_resultsView setStringValue:graphical_availability];

setStringValue: is the method you need.

From the NSTextField class reference:

Overview

The parent class, NSControl, provides the methods for setting the values of the text field, for example: setStringValue:, setDoubleValue:, etc.. There are corresponding methods to retrieve values.
