With my fist read through the release notes and API changes, they are still making significant changes but some areas seem to be locked down. There seem to be significant changes to Interface Builder, while not really adding may new Cocoa Touch objects. It seems they are still building the underlying IB infrastructure, before piling on new objects. That's fine I suspect.

Many of the API changes are of the properties type. That look like this:


Modified CLLocation.altitude

	Declaration
Old	@property(readonly) CLLocationDistance altitude
New	@property(readonly, nonatomic) CLLocationDistance altitude

While there were a large number of these changes, I suspect they are starting to lock down their APIs in much of the SDK.

Without digging too much into this method, I think I'm going to like it: -[UIViewController initWithNibName:bundle:]

I also want an example of how to use the Proxy Object in IB.


My application didn't compile because they removed UIModalView. But added UIActionSheet and they updated their sample code so it will only take me a few minutes to get back online.
