ios 6 - canperformaction not getting called on UITableViewController

问题

I am working on adding custom shared menu. I followed this stackoverflow post to implement this also seen some other posts.

It is working as it should be. But I am getting problem to get called canPerformAction when coming on this UITableView Controller by UITabBar item action which navigate me back to this view.

I tried to sovle this problem by using one of the answer on stackoverflow. But still canPerformAction not getting called in this case

Any help in this case is appritiated. Thanks

EDIT: My code looks like:

On viewDidLoad, i am doing following

UIMenuItem *sendByEmailMenuItem = [[UIMenuItem alloc] initWithTitle:@"Send e-mail" action:@selector(sendEmail:)];
[[UIMenuController sharedMenuController] setMenuItems: @[sendEmailMenuItem]];
[[UIMenuController sharedMenuController] update];

These are delegate methods i have used

- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}
- (BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
    return NO;
}
- (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {

}

- (BOOL) canPerformAction:(SEL)action withSender:(id)sender {
    return (action == @selector(sendEmail:));
}

- (BOOL)canBecomeFirstResponder {
    return YES;
}

- (void) sendEmail: (id) sender {
       //do stuff
}

I have added a call to become fist respoder on shouldShowMenuForRowAtIndexPath action

- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath {
    [self becomeFirstResponder];
    return YES;
}

This fixed my issue. Thanks
