reloadData does NOT work about customcollectionviewlayout HOT 6 CLOSED

I found a way to get this to work! Took me some time to figure it out, had to keep searching through different comments but if anyone Is interested.

I created a method named 'reload' which is set like this

- (void)reload { [self.collectionView reloadData]; self.itemAttributes = nil; [self prepareLayout]; }

So anytime I need to reload the data, I call this function instead of just the collectionView reloadData.
PS: Keep in mind that the itemSize array might also need to be reset but I am using this collection view across several scripts and I am setting up the itemSize based on the controller using it

from customcollectionviewlayout.

@adamhongmy Very possible. I never really use insert or remove cells... I usually just do reload data but you make a good point

but how about adding more? it seems this class is not design with all these in mind....

@adamhongmy Are you talking about adding cells? Well your data would come from an array and you can add/remove from that array during run time and then call the reload function above to reload the collection view with the new dataset

from customcollectionviewlayout.

@juliusbtesh that is one way to do it but reload the whole layout will cause lag if there are many data (like 200). Don't you think so?
