保存提示: *** Assertion failure in -[UICollectionView _createPreparedSupplementaryViewForElementOfKind:atIndexPath:withLayoutAttributes:applyAttributes:],/SourceCache/UIKit/UIKit-2903.2/UICollectionView.m:1401 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException',reason: 'the view returned from -collectionView:viewForSupplementaryElementOfKind:atIndexPath (UICollectionElementKindSectionHeader,<NSIndexPath: 0x145f3f50> {length = 2,path = 0 - 0}) was not retrieved by calling -dequeueReusableSupplementaryViewOfKind:withReuseIdentifier:forIndexPath: or is nil' (<UICollectionReusableView: 0x145f9400; frame = (0 0; 320 20); layer = <CALayer: 0x145f90c0>>) 之前一直都是用纯代码,现在用XIB和StoryBoard,经常碰到的问题,现在记录下来; let nib = UINib.init(nibName: "VCResultView",bundle: nil) _collectionView.register(nib,forSupplementaryViewOfKind: UICollectionElementKindSectionHeader,withReuseIdentifier: "header")
func collectionView(_ collectionView: UICollectionView,viewForSupplementaryElementOfKind kind: String,at indexPath: IndexPath) -> UICollectionReusableView { if kind == UICollectionElementKindSectionHeader{ return collectionView.dequeueReusableSupplementaryView(ofKind: kind,withReuseIdentifier: "header",for: indexPath) } else { return collectionView.dequeueReusableSupplementaryView(ofKind: kind,for: indexPath) } } 哈哈哈,这样就显示出来了。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
