Is there some documentation available on the net already? I could not find it on the Cocoa pages.

Follow the links in my weblog post to the actual NSController class documentation.

You also need to look at the documentation for the NSKeyValueCoding protocol in FoundationKit, as well as the documentation for the following methods in NSObject:


and the following methods in NSArray:


Also check out the following protocols in ApplicationKit:


Good to see that Apple uses ObjC rather than anything else for new features and additions! :-)

Yeah, almost all new software coming out of Apple is written in Objective-C.

There are also additions to the Objective-C language itself in gcc 3.3. In particular, it now has Java-style exceptions:

  @try {
    // something that might throw

    @throw anException;

  @catch (NSException *exception) {
    // handle the exception

  @catch (id unhandledException) {
    @throw; // re-raise the exception

  @finally {
    // do any necessary clean-up

And it has Java-style synchronization:

  @synchronized (someArray) {
    id object = [someArray lastObject];
    [someArray removeLastObject];

Throwing an Objective-C exception in a @synchronized block clears any locks.
