删除部分时，UICollectionView崩溃 [英] UICollectionView crashes when deleting section

问题描述

使用此代码时

  - (void)actionSheet:(UIActionSheet *)actionSheet 
             clickedButtonAtIndex:(NSInteger)buttonIndex
    {
        if (buttonIndex == 0) {

            [self removeCompany:companySelectedInActionSheet]; 

            NSIndexSet *indexSet = [NSIndexSet indexSetWithIndex:
                          indexPathSelectedInActionSheet.section];
            NSLog(@"IndexSet to delete from collection view: %@",indexSet);
            [self.collectionView deleteSections:indexSet]; 
        }
    }

我的应用有时会崩溃(10％的时间)，并出现以下错误:

my app crashes sometimes (10% of the time) with this error:

*** Assertion failure in -[UICollectionView _endItemAnimations], /SourceCache/UIKit_Sim/UIKit-2903.2/UICollectionView.m:3700

有什么想法可能有问题吗?

Any thoughts on what might be wrong?

删除之前提供的操作单是否有潜在问题?

Is the action sheet, which is presented before the deletion, a potential problem?

我需要在删除收藏夹视图"部分之前手动将其关闭吗?

Do I need to dismiss it manually before deleting the collection view section?

推荐答案

在 viewDidDisappear
