Re: Properties and bindings

It's working now, but I don't understand why. I've got two objects: MyController and MyModel. The interesting parts of the headers look like this: @interface MyModel : NSObject { NSInteger myInteger; } @property(assign) NSInteger myInteger; - (void)changeMyInteger; @end @interface

Re: Properties and bindings

you mean you want it to be read-only for other users, but you want the object to be able to set it itself without jumping through hoops? There's something about this in the properties description in the objective-c documents. What I've been doing for this (ie having semi-private properties

Re: Properties and bindings

when you do self.myInt under the covers you're really doing [ self setMyInt:123 ], and that method is KVO compliant so it fires the property change notification the textfield needs. myInt = 123 just sets the variable directly and skips the property change notification. On Sep 23, 2008,
