NSTextField resigning first responder

Question

I'm trying to have my text field resign first responder when the user is done editing it, like when they hit enter. The delegate method is getting called but what I have now doesn't work, what is the proper way to go about doing this?

- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText *)fieldEditor
{
    [fieldEditor resignFirstResponder];
    return YES;
}

From the docs on the -resignFirstResponder method:

Use the NSWindow makeFirstResponder: method, not this method, to make an object the first responder. Never invoke this method directly.

This code should do it:

[myWindow makeFirstResponder:nil];

It's causing crash but I think it's another problem, when I do fix it I think your solution will work. Thank You. – avizzini Dec 13 '10 at 17:59
The problem is definitely elsewhere. This is the proper way to cause *nothing* to be a window's first responder. – Joshua Nozzi Dec 13 '10 at 19:17
When I call this, it causes an infinite loop where the window asks the control control:textShouldEndEditing:, which calls makeFirstResponder: ad infinitum. – SG1 Mar 12 '13 at 16:30
@SG1: Post your code into a new question. There is nowhere near enough information in your comment to even guess. – Joshua Nozzi Mar 13 '13 at 14:35

- (void)controlTextDidEndEditing:(NSNotification *)obj {

   [self.window makeFirstResponder:view];
}

where "view" is the parent NSView of your NSTextView control.

I believe you are looking for the NSControl delegate method:

- (void)controlTextDidEndEditing:(NSNotification *)notif

Implement this method in your NSTextField delegate (easily set in IB).

Then your request to change the responder, such as

[self.window selectNextKeyView:self]

should work.

I am no expert in iPhone programming yet but the method you need to implement is "textFieldShouldReturn" implemented like this:

  - (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
    [theTextField resignFirstResponder];
    return YES;
}

Maybe I should have been more clear, Its not for an iPhone application. The method you showed is for UITextField delegate, which is for Cocoa Touch. – avizzini Dec 13 '10 at 16:48
This not in osx sdk the every class begins with UI belongs to iOS not OSX – damithH Jan 31 '14 at 05:22
