Reset NSTextField's text to empty string — setText: doesn't work

问题

I have an NSTextField, and I need a button to reset the text of the field. How would I do that? I have been trying this:

[textBox setText:@""];
textbox.text = @"";

That does not work, but I have researched, and found nothing on how to set the text, only how to get the text.

回答1:

If it is OSX and NSTextField then use :

[textBox setStringValue:@""];

回答2:

Try this code:

theLabel.text = @"this is some text";
[self.view addSubView:theLabel];

Here, the label is the text field.
