Where I work we have spent a fair amount of trying unsuccessfully to get self-sizing collection view cells to work as described by Apple documentation with UICollectionViews that have any sort of complexity. I would suggest trying to implement the sizeForItemAtIndexPath delegate method to see if that solves your problem. Sorry if the name of the method is slightly off. I can’t look it up at the moment.
