ios - Swift - dequeueReusableCellWithReuseIdentifi

问题:

I have a ViewController with 3 views :

• Header (UIView)
• TabBar (UIView)
• UIView3 (UIView)

In my UIView3 I have a collectionViewController. A key element is that I put my collectionViewController.scrollEnable = False because otherwhise, when I'm scrolling, only the UIView3 is scrolling and I want my entier screen to scroll (so that if we scroll enough my Header and Tabbar are hidden.

So this is what I have :

And this is how my screen looks like :

Which is perfect. But, when I'm scrolling down, this is what it should looks like :

But instead, it looks like this :

I think my problem comes from the "dequeueReusableCellWithReuseIdentifier" function which doesn't see that I'm scrolling but I have no idea how to "refresh" the scroll value so it loads the end of cells 3-4 and also the cells 5-6.

Do you have any idea ?
