Thanks for the explanations: it does make some kind of sense now.
The reason I was looking at both forms is that I want the myInt
property to be read-only, but I want the MyObject instance to be
able to set it. If I do this:
@property(readonly) NSInteger myInt;
I can't do this in MyObject:
self.myInt = 123;
without generating a compiler error. And as you've all explained, I
can't do this either:
myInt = 123;
because the textfield value won't be changed. Is Jason's suggestion
the best way to get around this problem?
Yes, in this case you would want to do the manual KVO as I
demonstrated earlier. If you just surround your
ivar update with those messages, your bindings and such will behave as
expected.
