On iphone 3.0 how to disable Cut, Copy and Paste option

Question

Hello everybody,

Does any one know, how can i disable cut, copy and paste option on iPhone 3.0?

Thanks for your help and time.

Answer 1

Any responder (UIView or UIWindow subclass) can override the canPerformAction:withSender: method, so you could just return NO for all the actions you don't want to permit.

See the UIResponder documentation...

Answer 2

I, too, couldn't find much documentation on using canPerformAction:withSender: for this purpose. So, I settled for clearing the pasteboard when exiting the application. In my AppDelegate.m:

- (void)applicationWillTerminate:(UIApplication *)application {

  NSLog(@"application terminating");

  // Clear pasteboard to prevent pasting into other applications:
  UIPasteboard *pasteBoard = [UIPasteboard generalPasteboard];
  pasteBoard.items = nil;

}

This worked well for my user-annotated reference application. I don't mind users copying and pasting within my application, but I'd rather they not republish my original content.

At some point I'd like more fine-grained control, perhaps with canPerformAction:withSender:, so that I can allow users to copy/paste the content they do create themselves.

Override this method in the controller class.

// Hide cut/copy/paste menu

-(BOOL)canPerformAction:(SEL)action withSender:(id)sender {

if ( [UIMenuController sharedMenuController] )
{
    [UIMenuController sharedMenuController].menuVisible = NO;

}
return NO;

}
