I'm trying to learn how to use bindings. MyObject has an NSInteger myInt. I used @property and @synthesize to make myInt into a property. In IB I bound an NSTextField to the myInt property. Now when I do this:

	self.myInt = 123;

when initialising MyObject, the value shows up in the text field. But if I do this instead:

	myInt = 123;

the textfield just shows '0'. What's happening here?

Others already answered this, but if (for some reason) you want to do this manually, you can enable the KVO as so:


[self willChangeValueForKey:@"myInt"];
myInt = 123;
[self didChangeValueForKey:@"myInt"];
