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"];
