有谁知道如何将按钮添加到内部的补充视图页脚UICollectionView?我试图编写一个代码,但我不断收到错误,我目前在viewForSupplementaryElementOfKind函数中有这个错误;错误:
UICollectionView
viewForSupplementaryElementOfKind
'collectionView(_:viewForSupplementaryElementOfKind:atIndexPath:)' 的无效重新声明
谢谢!!:)
appcoda 上有一个不错的 Tutorail,关于 Collection View 中的 Supplementary View。
