They don't have to actually be in separate nibs, do they? That's not what I gleaned from the WWDC video. > BTW, it can be much harder to vary the row height based on the cell view. > You'd either need to cache all possible cell view heights in advance, or have > a mechanism to calculate the cell view heights before view instantiation, or > some combination of the two approaches. Yeah. Typically on iOS I just get the cell for the row in the delegate and return its height. I had hoped there was a better mechanism in the context of bindings and autolayout. In the philosophy of autolayout, the cells should know their own height. Anyway, I'll just implement the delegate method.
