I'm trying to add one subview (view from an NSViewController) for every element in a dictionary to a NSScrollView to get kind of a tableview, but with much more flexibility over the cells.
Is it possible to place (programmatically) e.g. 100 subviews underneath each other so that you have to scroll down the NSScrollView to get to the last element?
The short answer is yes. I have done this before, and I assure you that it will work. Let me also assure you that it is not quite as simple as it looks ;)
The way to do this is to maintain one content view, in which you add all of your custom rows as subviews programmatically. Note that you will either have to resize the contentView before adding all of the rows, or you will have to turn off autoresizing for the row views. Set the documentView of your scrollView to this custom contentView, and you should be good to go.
