Inline Date Picker with static cells

Hi, could you please help me implement an inline date picker in static cells. I have tried the Apple DateCell example project, but the first thing is that it's quite cryptic, and the second thing is that it's based on dynamic prototype cells adding and removing cells, and what I want to do is just to collapse the cell that holds the date picker and show/hide it when the cell above it is clicked to input the date.

I've been trying to follow this tutorial, and while I seemed to have figured out the Part 1 with dynamic cells (highly recommended, much clearer than the Apple DateCell project), the second part doesn't seem to work in iOS 7.1 (as noted in one of the comments there) - the date picker still stays visible when its holding cell's height is set to 0.

I've also found this algorithm, but it seems to do the same thing as in the example above.

Any idea how to do what I need to do? Is there some other way to do it perhaps, and collapsing the cell's height to 0 isn't the best way?
