Slow when expanding

[georgekfoury]

I have around 100 items in the collectionview with picture and text. When opening a section, if there are 10,20 items in the expanded section it's fine. When it contains 100 it takes around 1.5 seconds which is laggy for the user. Any solutions? (Maybe because each time i expand, the whole collectionview loads?) Thank you!

Have you tested without creating and assigning the UIImage in each cell? Loading 100 images into memory is always slow.

Yes it is still slow, the problem is that the number of the cells is high. Is there any way not to load all of the cells on expanding? (not entering cellForRowAtIndexPath) Thank you

There is no way I am aware of.
