Adding a dynamic custom UIMenuItem to Copy & Paste Menu before it shows

Question

I have successfully been able to add a custom UIMenuItem to the Copy & Paste menu in my iPhone app, and even subclassed UITextView to get r

Answer 1

At startup somewhere:

UIMenuItem *testMenuItem = [[UIMenuItem alloc] initWithTitle:@"Test" action:@selector(test:)];
[UIMenuController sharedMenuController].menuItems = [NSArray arrayWithObject:testMenuItem];
[testMenuItem release];

And in your UITextView or UITextField subclass:

@implementation MyTextView
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    if (action == @selector(test:)) {
        // Return YES only if it's possible to perform the action at this time
        return YES;
    }
    return [super canPerformAction:action withSender:sender];
}
- (void)test:(id)sender {
    // Perform the action here
}
@end
