Small issue with "AppController"

I am trying to dissect "Sketch-112" and in the process wrote something small which is not working quite the way I wish.

SetUP.

AppController with 1 IBOutlet, (An NSTextField) which is instantiated in the nib. I just left the word "label" intact on the NSTextField.

In the init method of AppController this:

Code:

NSColor * g = [ NSColor greenColor];
		NSString *s = @"Hello World";
		NSTextField *f = [[NSTextField alloc]init];
		[f setBackgroundColor:g];
		[f setStringValue:s];
		NSLog(@"The value of TextField \"f\" is: %@",[f stringValue]);
		[self setTextField: f];

and the relevant setter this:

Code:

- (void) setTextField: (NSTextField*) t
{
	if ( _textField == t)
		return;
	[_textField release];
	[t retain];
	_textField = t;
	NSLog(@"The value of TextField \"_textField\" is: %@",[_textField stringValue]);
	
	
}

Now the output is this:

So, the problem seems to be that the word "Label" is added after the setter is called. Could anyone possibly explain the issue and how to get around this?

Thanks ...in advance...as usual.

 

Yes...thanks chown. I figured something like this was happening.

Makes sense. I guess that's the problem when one is just playing around. But...it's all part of the learning curve. So, thank you for your insight.

Well...I will have to try that again, as I placed the code there but had a similar result. But...I probably did something incorrectly.

Exactly.

Good point. This all started with a challenge in Hillegass's book, creating ovals in a document based app. (Chapter 18) . I take those challenges seriously, else all that happens when you end the book is that you know what's in the book!!! I realized that even though I had done things with Document based apps in the book, I really did not have a good grasp of the architecture, and having spent hours looking online, many people recommended this example. The tangent from this example , of course, was looking at the issue of properties and ivars, and where exactly to "expose" them...another poorly defined term. So, to answer your really short question with this incredibly long answer, I wrote this just to test my understanding of properties/ivars. My expectation was that I could set the label to read "Hello world" on a green background!! But, your insight helps, for which I thank you.

Further stuff. Out of curiosity, in order to understand this control a little better, I moved the relevant code to "awakeFromNib", but still get the same result ie the word "label" is still not replaced. Am I still missing something?

Output now is:

Note that I added a macro to ID the method
