How to get UIMenuController work for a custom view?

Question

I\'m trying to get the following code work:

UIMenuController * menu = [UIMenuController sharedMenuController];
[menu setTargetRect: CGRectMake(100, 100, 100,

If you're implementing a custom view and that view is supposed to be the responder (as opposed to some other view, like a UITextField), you need to override the canBecomeFirstResponder function in your view and return YES:

- (BOOL)canBecomeFirstResponder {
    return YES;
}

then, when you're displaying the menu, you should do something like the following:

- (void)myMenuFunc {
    if (![self becomeFirstResponder]) {
        NSLog(@"couldn't become first responder");
        return;
    }

    UIMenuController *theMenu = [UIMenuController sharedMenuController];
    CGRect selectionRect = CGRectMake(0, 0, 0, 0);
    [theMenu setTargetRect:selectionRect inView:self];
    [theMenu setMenuVisible:YES animated:YES];
}
