bealex / awesometableanimationcalculator Goto Github PK

We are using AwesomeTableAnimationCalculator in our app, and we are happy with it so far. Except that we are now facing an issue where we need to fold/unfold sections (e.g. for those sections to be able holding 0 rows); I assume for this moment it is not possible to have a section model with no cell models associated with it? Since Section Models are being built from Cell Models.

I haven't found a solution to cleanly build a mechanism for such collapse/expand feature. Regarding this, I wonder if you might consider adding this feature, or would it be better if we forked and done this by ourselves?

Thanks in advance

We tried to use the AwesomeTableAnimationCalculator in production for our app, but it did not work out due to performance issues.

We observed the significant CPU usage hit on diff calculation. The diff calculation involves plenty of Array.indexOf() calls, and those cost ~O(n) where n is the size of the array.

I've tried to port the framework to use NSOrderedSet where the lookup is O(1), but did not succeed because ordered set is looking objects up not by hash but by memory address, and as log as the data source objects are copied, the lookup can not be successful.

Possible option could be to use one of implementations of ordered set that are done in swift.

PS: If needed I can provide the port implementation that I've done to try NSOrderedSets

Привет! Столкнулся с траблой, где нужно определить имеется ли уже определенный элемент (ACellModel) в модели, а если есть, то узнать в какой секции. Я стал перебирать sections в модели, и выяснилось, что у нее нету связи с моделями ячеек. Пробовал перебирать items, у них тоже никаких связей с секциями не оказалось. Было бы здорово увидеть подобные связи в публичном API.

Хотелось бы иметь поддержку Swift 3.0, хотя бы на отдельной ветке. Спасибо!
