ios - -[_UIFlowLayoutSection 中心] : unrecognized selector sent to instance

Question

我该如何修复这个崩溃:

-[_UIFlowLayoutSection center]: unrecognized selector sent to instance.

我在做:

UICollectionViewFlowLayout *collectionLayout = [[UICollectionViewFlowLayout alloc] init];    
collectionLayout.minimumInteritemSpacing = 0.0;    
collectionLayout.minimumLineSpacing = 0.0;    
collectionLayout.sectionInset = UIEdgeInsetsMake(0.0,0.0,0.0,0.0);    
[collectionLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];    
[_collectionView setCollectionViewLayout:collectionLayout];

Answer 1

在设置流布局之前尝试重新加载 collectionView。

我遇到了同样的问题，通过在设置 flowlayout 之前重新加载 collectionView 解决了这个问题。
