Not sure what you mean by the "associated text view" of the control. Do you
mean the field editor of the control? I have subclassed NSTextField and
overridden becomeFirstResponder. NSTextField is a subclass of NSControl which
is a subclass of NSView.

Yes I think that is the case. The following code works.
[self performSelector:@selector(selectText:) withObject:self afterDelay:0.1];

The delegate methods textDidBeginEditing: and controlTextDidBeginEditing: are
not called when clicking into the view. They are called when the first edit is
actually attempted. So that did not work.
In fiddling around with afterDelay: values this is what I found.
afterDelay:0.01 // This did not work. Text not selected.
afterDelay:0.02 // This works. Text is selected.
afterDelay:0.1 // This works. Text is selected.
afterDelay:1.0 // This works but the delay is too long.
So do you think I am safe using this call.
[self performSelector:@selector(selectText:) withObject:self afterDelay:0.1];
