First, bindings are not always the best approach to solve any particular
problem. They can be useful, but when you run up against an area where the
bindings approach seems excessively difficult, you should consider going the
non-bindings route.
For example, in the view controller or window controller, you would have an
outlet to the text field (say, "versionLabel"). In the controller's
-viewDidLoad or -windowDidLoad method, you would simply do:
self.versionLabel.stringValue = [[NSBundle mainBundle]
objectForInfoDictionaryKey:@"CFBundleShortVersionString”];
If you really want to use bindings, then you could create a read-only property
on your view controller or window controller class. You would implement its
getter to return the above value:
@property (readonly, nonatomic) NSString* mainBundleShortVersion;
- (NSString*) mainBundleShortVersion
{
return [[NSBundle mainBundle]
objectForInfoDictionaryKey:@"CFBundleShortVersionString”];
}
Once you've created such a property, you can bind to it.
