NSImageView setImage won't set image

I am trying to set image for an NSImageView instance object in a Cocoa project. My code looks like this: 

itemTableCellView * xx = [tableView makeViewWithIdentifier:@"MainCell" owner:self];
    xx.label.stringValue = [tempCi simpleTxt];
    xx.img = [[NSImageView alloc]initWithFrame:CGRectMake(48, 48, 48, 48)]];
    NSImage * localimage = [NSImage imageNamed:@"menubar icon"];
    [xx.img setImage:localImage];
    return  xx;

The variable imgis of type NSImageView. The variable localImage loads the correct image, I have checked it in the log. The variable lable is initialized correctly and gets the right value

I just keep on getting empty NSImageViews in my app.

Your NSImageView is initialized with no size (it's frame equals NSZeroRect), also you don't add the image view to any subview.

Well, yet another quirk of Objective-C!

I found out that even when a NSImageView is a property of an NSView, it needs to be added to it through: 

[xx addSubview:xx.img];

Well, played Cocoa, very well played!
cheers!

You should use

xx.img = [[NSImageView alloc] initWithFrame:CGRectMake(x, y, width, height)];

Or, maybe, as img is property, you don't need to init it at all? And just use 

xx.img.frame=CGRectMake(x, y, width, height);

when you create your NSimageView,try doing an initwithframe:. This will set a size for the NSImageView. I believe that you might be drawing in a rect of size zero otherwise.
