For instance, if you want your width to be dynamic then your cell needs a height constraint. Things you do need to be aware of is that your cell needs to be more seriously constrained than a Table View Cell. Just be wary that Xcode 6 broke a bunch of stuff with iOS 7 so, if you support iOS 7, you will need to do stuff like ensure the autoresizingMask is set on the cell's contentView and that the contentView's bounds is set as the cell's bounds when the cell is loaded (i.e. I won't go to in to detail about this as there's a brilliant SO post about configuring constraints for a cell. Create and configure cells with Auto Layout This comes in 2 flavours Auto-Layout or custom override of preferredLayoutAttributesFittingAttributes. Add support for sizing on your cell subclass Set estimatedItemSize on UICollectionViewFlowLayoutįlow layout will become dynamic in nature once you set the estimatedItemSize property. There are two things you need to setup for self sizing cells to work. Self sizing cells are only supported with flow layout so make sure thats what you are using. A word of caution when proceeding with self sizing cells. My conclusion is that self sizing cells are great in theory but messy in practice. I have now updated the repo to include several examples of different configurations for self sizing cells. SystemLayoutSizeFittingSize renamed to systemLayoutSizeFittingĪfter seeing my GitHub solution break under iOS 9 I finally got the time to investigate the issue fully. PreferredLayoutAttributesFittingAttributes renamed to preferredLayoutAttributesFitting and use auto sizing ![]() Please consider updating the new API Updated for Swift 5 This answer is outdated from iOS 14 with the addition of compositional layouts.
