cannot pull to refresh if contentSize is smaller than frame

[disorderdev]

I tried to set alwaysBounceVertical=YES, but I found that if infiniteScrolling is added at the same time, then both of them will show and animate

If the height of the content is less than the height of the screen(or tableView), set contentSize for tableView equal height of the screen.

FWIW, I ran into this same (or at least a similar) problem. I had a UIScrollView whose contents I constructed on my own (not a UITableView). contentSize was smaller, thus I couldn't pull. @wsnnn's suggestion got me on the right track, but I couldn't make the contentSize equal to the height of my enclosing view -- I had to make it the height + 1. That made things work.

@hsoi can you give an example of what you did please? I have the same problem and tried the following, to no avail:

[collectionView setContentSize:CGSizeMake(view.frame.size.width, view.frame.size.height + 1)]

I did exactly what I wrote in my comment, which is essentially the same thing you're doing except I was working on a pure UIScrollView, not a UICollectionView (nor UITableView) which may be having an interaction effect with other layout calculations. Sorry.

I ended up subclassing UICollectionViewFlowLayout and overriding the collectionViewContentSize method

var alwaysBounceVertical: Bool { get set }

If this property is set to true and bounces is true, vertical dragging is allowed even if the content is smaller than the bounds of the scroll view. The default value is false.
