Position Popover when NSToolbarItem is pressed

Question

I want to show a Popover when the user clicks on a NSToolbarItem. However, in my IBAction I do not get a NSView instance for my sender, which I find really weird.

I get to display the Popover (rather dislocated now by using window.contentView as my view instead of the toolbar's - see image):

- (IBAction)accountIconTouched:(NSToolbarItem *)sender {

    // NSView *view = [sender view]; // returns nil
    NSView *view = self.window.contentView;

    [self.accountPopover showRelativeToRect:[view bounds] ofView:view preferredEdge:NSMinYEdge];


}

So how do I get the view for my NSToolbarItem so that the Popover shows up.

This is the error I get from the console:

Answer 1

It seems like there's a solution where you assign an IBOutlet to your toolbar Item, and get the view from there. To give it a try check here.
