iPhone UIView resources

I have been looking for li开发者_如何学Cttle more deeply UIView introduction resources, such as e-book, video or tutorials. Positioning, subclassing, frame, bouds, subviews, creating programmatically, loading from xib, both, etc.

I didn't find good resource about it, I would like to hear suggestions ?

Regards

The Apple documentation for views is actually very good for this. The Big Nerd Ranch iPhone book has given me many Aha! moments, especially about view controllers. Erica Sadun's iPhone Developers Cookbook has always been good for nitty gritty information.

Those are a few I've found, but like you I'd love to have just one really great book or tutorial to fill in the many gaps in my UIView knowledge.
