[英]UICollectionView crashes when deleting section
When using this code 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];
}
}
my app crashes sometimes (10% of the time) with this error: 我的应用有时会崩溃(10%的时间),并出现以下错误:
*** Assertion failure in -[UICollectionView _endItemAnimations], /SourceCache/UIKit_Sim/UIKit-2903.2/UICollectionView.m:3700
Any thoughts on what might be wrong? 有什么想法可能有问题吗?
Is the action sheet, which is presented before the deletion, a potential problem? 删除之前提供的操作表是否可能存在问题?
Do I need to dismiss it manually before deleting the collection view section? 在删除“收藏夹视图”部分之前,是否需要手动将其关闭?
在viewDidDisappear
上将表视图委托设置为nil
