Question

ios9.0以后 uicollectionview 拖拽 怎么固定某个cell无法移动,别的cell拖动时也无法挤压这个cell?用iOS9.0以后的方法,有人知道吗?

Answer 1

- (NSIndexPath *)collectionView:(UICollectionView *)collectionView targetIndexPathForMoveFromItemAtIndexPath:(NSIndexPath *)originalIndexPath toProposedIndexPath:(NSIndexPath *)proposedIndexPath{
    
    if([self.adapter checkEditableOfIndexPath:proposedIndexPath]){
        return proposedIndexPath;
    }
    return originalIndexPath;
}

UICollectionView代理方法，判断proposedIndexPath是否可编辑，返回合适第indexpath
