Question

In a Mac OS X Cocoa application, I have an application-modal dialog with text fields that are bound to the Shared User Defaults Controller. If I edit a text field, and then tab away from it before hitting the OK button, then everything works as desired. However, if I start editing a field, then hit the Return key to trigger OK, the old value of the field remains in NSUserDefaults.

So, how can I force the changed field to affect the bound value when editing is ‘incomplete’?

From perusing documentation, I think I might be able to call NSControl’s validateEditing method for each of the text fields before dismissing the dialog, but it seems like there should be a simpler way.

FWIW, here is the code that displays the dialog:

- (void)showDialog {     [NSApp activateIgnoringOtherApps:YES];     [NSApp beginSheet:startTimerDialog        modalForWindow:nil         modalDelegate:nil        didEndSelector:nil           contextInfo:nil];     [NSApp runModalForWindow:startTimerDialog];     [NSApp endSheet:startTimerDialog];     [startTimerDialog orderOut:self]; } 

The OK button (actually titled ‘Start’) is targetted to this method:

- (IBAction)startTimerDialogStartButtonWasClicked:(id)sender {     [self closeModalDialog:sender];      // Then, call methods that read values from NSUserDefaults     // ...     }

Send the user defaults controller a commitEditing message.
