I spent some time earlier today playing with the UIMenuController available in the iOS SDK and realized two thing: sometimes Apple’s examples suck and having an environment that often gives no feedback is terrible.

In this case, I implemented a copy of an example that was supposed to present a semi-modal cut / copy / paste menu. It didn’t. After spending nearly an hour trying to identify why nothing was happening, I found I had missed copying a line. Anyways, for the record, here is the concise example of how to present a UIMenuController:

@implementation SampleViewController

#pragma mark - Helpers

- (void)menu
{
  [self becomeFirstResponder];

  UIMenuController *menu = [UIMenuController sharedMenuController];

  [menu setTargetRect:CGRectMake(100, 100, 0, 0) inView:self.view];
  [menu setMenuVisible:YES animated:YES];
}

#pragma mark - Main

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
  [self menu];
}

- (BOOL)canBecomeFirstResponder
{
  return YES;
}

#pragma mark - Actions

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
  if (action == @selector(cut:) || action == @selector(copy:)) return YES;
  return NO;
}

- (void)cut:(id)sender { NSLog(@"cut"); }
- (void)copy:(id)sender { NSLog(@"copy"); }
