IOS swift UICollectionView中cell的间距如何设置，请大神讲解。

Question

最好能有个demo，感激不尽~

Answer 1

You can use autolayerout to set it in the storyboard. This is my general approach because it is simple and fast. Alternatively, you can use this protocol UICollectionViewDelegateFlowLayout

Rewrite a function of the collectionview below

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets { 
        return sectionInsets
    }

Then define the following variable outside the function, which is the same as the value returned above.

 private let sectionInsets = UIEdgeInsets(top: -5.0, left: 5.0, bottom: 0.0, right: 5.0)

For the rest, you can refer to this http://www.cnblogs.com/ios8/p...

Answer 2

Do you know how to set up OC? The interfaces are similar

Answer 3

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets { 
        return sectionInsets
    }

Override this method, which is used to specify the interval, the upper, lower, left, and right intervals.
