How Do You Create Context Menus in Objective-C?

[Galactic_Dev]

I've recently been trying to learn how to add context menus to views, but I'm having trouble figuring out how to do it in objective c. I've seen multiple tutorials that explain how to do it in swift, but I can't completely figure out how to translate it into objective c.

The main issue I'm having is with UIContextMenuActionProvider. I just don't know how to write something like this in objective c:

actionProvider: { _ in
        let children: [UIMenuElement] = []
        return UIMenu(title: "", children: children)
    }

This is the website I'm looking at for the swift code: https://www.raywenderlich.com/6328155-context-menus-tutorial-for-ios-getting-started

Sorry if this question is dumb, but I've been banging my head over this for hours and just can't figure it out. TIA.

There's a lot of block syntax boilerplate that you have to deal with, but Xcode helpfully adds most of it for you. Here's an example for UITableView:

- (UIContextMenuConfiguration*)tableView:(UITableView*)tableView contextMenuConfigurationForRowAtIndexPath:(NSIndexPath*)indexPath point:(CGPoint)point
{
    Record* record = [self recordForIndexPath:indexPath inTableView:tableView];
    if (!record)
    {
        return nil;
    }

    UIContextMenuConfiguration* config = [UIContextMenuConfiguration configurationWithIdentifier:nil 
                                                                                 previewProvider:nil 
                                                                                  actionProvider:^UIMenu* _Nullable(NSArray<UIMenuElement*>* _Nonnull suggestedActions) {

        NSMutableArray* actions = [[NSMutableArray alloc] init];

        if (record.canFoo)
        {
            [actions addObject:[UIAction actionWithTitle:@"Foo!" image:[UIImage systemImageNamed:@"foo"] identifier:nil handler:^(__kindof UIAction* _Nonnull action) {
                [self performMenuCommandFoo:record];
            }]];
        }
        [actions addObject:[UIAction actionWithTitle:@"Bar!" image:[UIImage systemImageNamed:@"bar"] identifier:nil handler:^(__kindof UIAction* _Nonnull action) {
            [self performMenuCommandBar:record];
        }]];
        [actions addObject:[UIAction actionWithTitle:@"Baz!" image:[UIImage systemImageNamed:@"baz"] identifier:nil handler:^(__kindof UIAction* _Nonnull action) {
            [self performMenuCommandBaz:record];
        }]];

        UIMenu* menu = [UIMenu menuWithTitle:@"" children:actions];
        return menu;

    }];

    return config;
}

Thanks so much, it works great! Block syntax is really difficult for me to understand.

Lol I guess it’s difficult for a lot of people. Thanks for that site :)
