UIMenuController with custom item not working with UICollectionview

Question

I have added custom menu controller when long press on UICollectionViewCell

    [self becomeFirstResponder];
    UIMenuItem *menuItem = [[UIMenuItem alloc] initWithTitle:@"Custom Action"
                                                      action:@selector(customAction:)];
    [[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObject:menuItem]];
    [[UIMenuController sharedMenuController] setTargetRect: self.frame inView:self.superview];
    [[UIMenuController sharedMenuController] setMenuVisible:YES animated: YES];

canBecomeFirstResponder Is also being called

- (BOOL)canBecomeFirstResponder {
    // NOTE: This menu item will not show if this is not YES!
    return YES;
}

//This method is not being called

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    NSLog(@"canPerformAction");
    // The selector(s) should match your UIMenuItem selector
    if (action == @selector(customAction:)) {
        return YES;
    }
    return NO;
}

I have Also Implemented these methods

- (BOOL)collectionView:(UICollectionView *)collectionView
      canPerformAction:(SEL)action
    forItemAtIndexPath:(NSIndexPath *)indexPath
            withSender:(id)sender {


    if([NSStringFromSelector(action) isEqualToString:@"customAction:"]){
        NSLog(@"indexpath : %@",indexPath);
        UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"warning.." message:@"Do you really want to delete this photo?" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alertview show];
        return YES;
    }

    return YES;

}

- (BOOL)collectionView:(UICollectionView *)collectionView shouldShowMenuForItemAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}

- (void)collectionView:(UICollectionView *)collectionView
         performAction:(SEL)action
    forItemAtIndexPath:(NSIndexPath *)indexPath
            withSender:(id)sender {
    NSLog(@"performAction");
}

Though it is showing only "cut, copy, and paste" menus

Answer 1

Maybe a bit late but i maybe found a better solution for those who are still search for this:

In viewDidLoad of your UICollectionViewController add your item:

UIMenuItem *menuItem = [[UIMenuItem alloc] initWithTitle:@"Title" action:@selector(action:)];
[[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObject:menuItem]];

Add the following delegate methods:

//This method is called instead of canPerformAction for each action (copy, cut and paste too)
- (BOOL)collectionView:(UICollectionView *)collectionView canPerformAction:(SEL)action forItemAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
        if (action == @selector(action:)) {
            return YES;
        }
        return NO;
    }
    //Yes for showing menu in general
    - (BOOL)collectionView:(UICollectionView *)collectionView shouldShowMenuForItemAtIndexPath:(NSIndexPath *)indexPath {
        return YES;
    }

Subclass UICollectionViewCell if you didn't already. Add the method you specified for your item:

- (void)action:(UIMenuController*)menuController {

}

This way you don't need any becomeFirstResponder or other methods. You have all actions in one place and you can easily handle different cells if you call a general method with the cell itself as a parameter.

Edit: Somehow the uicollectionview needs the existence of this method (this method isn't called for your custom action, i think the uicollectionview just checks for existance)

- (void)collectionView:(UICollectionView *)collectionView performAction:(SEL)action forItemAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {

}
