Question

Answer 1

I think it is because Apple wants you to use the new UIActivity control.

Here it's the documentation:

http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIActivity_Class/Reference/Reference.html

Here it's a custom control developed to support many third party apps:

And this question solves how could you make your own UIActivity:

So, if you don't want the user can use copy: and print: methods just pass this activities to the UIActivityViewController, like this:

[activityView setExcludedActivityTypes:[NSArray arrayWithObjects:UIActivityTypeCopyToPasteboard, UIActivityTypePrint, nil]];

All the default activities are listed at the bottom of the Apple's documentation link.
