NSTextView doesn't call controlTextDidChange:

Question

I have a class ("TextEditorViewController") within there is a NSTextView ("textView") Object. I've connected it with the NSTextView in my .xib file. Here my .h file:

#import <Foundation/Foundation.h>

@interface TextEditorViewController : NSObject {
    IBOutlet NSTextView *textView;           // connected in MainMenu.xib
    IBOutlet NSTextField *displayCharacters; // connected in MainMenu.xib
}

@end

And here is my .m file:

#import "TextEditorViewController.h"    

@implementation TextEditorViewController

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    NSLog(@"applicationDidFinishLaunching called"); // printed to the debugger
    [textView setDelegate:(id)self];
}

- (void)controlTextDidChange:(NSNotification *)obj {
    NSLog(@"controlTextDidChange called"); // don't printed to the debugger ???
    [displayCharacters setIntValue:[[textView string] length]];
}

@end

But when I change the text in my NSTextView it don't call controlTextDidChange:! Why?

Thanks for answers! =)

It worked after rebuilding the files in a new project. Seems like a file management configuration issue.

Move the delegate part to viewDidLoad.
Why do you don't put this to a viewcontroller?

You mean awakeFromNib? viewDidLoad doesn't exist for Mac OS X. I tried awakeFromNib but it still don't work :( – qwertz Mar 05 '12 at 12:45
Sorry I thought it's about iOS. – FrediWeber Mar 05 '12 at 12:49
Nothing... I called NSLog in controlTextDidChange: but there is no output. When I set a breakpoint in that method it won't stop if I change the text. – qwertz Mar 05 '12 at 12:53
Haha, it can't be iOS because NSTextField & NSTextView :D – qwertz Mar 05 '12 at 12:54
Please set a breakpoint to setDelegate. Let's see if the Textview already exist. – FrediWeber Mar 05 '12 at 12:54
Yes, awakeFromNib: is called but controlTextDidChange: don't respond. – qwertz Mar 05 '12 at 14:08
Yes but is the textarea nil then? – FrediWeber Mar 05 '12 at 14:15
Do you implement the protocol like mentioned in another answer? – FrediWeber Mar 05 '12 at 14:29
