单元格动画停止分数必须大于起始分数 [英] Cell animation stop fraction must be greater than start fraction

问题描述

我在表视图单元格中使用动画...当单元格完全可见时，动画工作正常。如果当时任何单元格部分可见，由于动画我的应用程序在行[_Mytableviewobject endUpdates]中崩溃了;

I m using Animation in table view cell...Animation is working fine when cell is totally visible.if any cell is partially visible at that time due to Animation my app is getting crashed at the line [_Mytableviewobject endUpdates];

崩溃日志=由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'单元格动画停止分数必须大于开始分数'

Crash Log=Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cell animation stop fraction must be greater than start fraction'

代码部分：

-(void)sectionHeaderView:(SectionHeaderView*)sectionHeaderView sectionOpened:(NSInteger)sectionOpened
{
     //ENSLog(self, _cmd);
    [_caseTable reloadData];
    NSInteger countOfRowsToInsert = 1;
    SectionInfo *sectionInfo = [self.sectionInfoArray objectAtIndex:sectionOpened];
    sectionInfo.open = YES;


    NSMutableArray *indexPathsToInsert = [[[NSMutableArray alloc] init] autorelease];
    for (NSInteger i = 0; i < countOfRowsToInsert; i++) 
    {
        [indexPathsToInsert addObject:[NSIndexPath indexPathForRow:i inSection:sectionOpened]];
    }

    NSMutableArray *indexPathsToDelete = [[[NSMutableArray alloc] init] autorelease];
    NSInteger previousOpenSectionIndex = self.openSectionIndex;
    if (previousOpenSectionIndex != NSNotFound)
    {
        SectionInfo *previousOpenSection = [self.sectionInfoArray objectAtIndex:previousOpenSectionIndex];
        previousOpenSection.open = NO;
        [previousOpenSection.headerView toggleOpenWithUserAction:NO];
        NSInteger countOfRowsToDelete = 1;
        for (NSInteger i = 0; i < countOfRowsToDelete; i++)
        {
            [indexPathsToDelete addObject:[NSIndexPath indexPathForRow:i inSection:previousOpenSectionIndex]];
        }
    }

    // Style the animation so that there's a smooth flow in either direction.
    UITableViewRowAnimation insertAnimation;
    UITableViewRowAnimation deleteAnimation;
    if (previousOpenSectionIndex == NSNotFound || sectionOpened < previousOpenSectionIndex) 
    {
        insertAnimation = UITableViewRowAnimationTop;
        deleteAnimation = UITableViewRowAnimationBottom;
    }
    else
    {
        insertAnimation = UITableViewRowAnimationTop;
        deleteAnimation = UITableViewRowAnimationTop;
    }

    // Apply the updates.
    [_caseTable beginUpdates];
    [_caseTable deleteRowsAtIndexPaths:indexPathsToDelete withRowAnimation:deleteAnimation];
    [_caseTable insertRowsAtIndexPaths:indexPathsToInsert withRowAnimation:insertAnimation];
    [_caseTable endUpdates];
    //ExNSLog(self, _cmd);

    self.openSectionIndex = sectionOpened;
    //ExNSLog(self, _cmd);

}




-(void)sectionHeaderView:(SectionHeaderView*)sectionHeaderView sectionClosed:(NSInteger)sectionClosed
{
     //ENSLog(self, _cmd);
    SectionInfo *sectionInfo = [self.sectionInfoArray objectAtIndex:sectionClosed];
    sectionInfo.open = NO;
    NSInteger countOfRowsToDelete = [_caseTable numberOfRowsInSection:sectionClosed];
    if (countOfRowsToDelete > 0)
    {
        NSMutableArray *indexPathsToDelete = [[[NSMutableArray alloc] init] autorelease];
        for (NSInteger i = 0; i < countOfRowsToDelete; i++) 
        {
            [indexPathsToDelete addObject:[NSIndexPath indexPathForRow:i inSection:sectionClosed]];
        }
        [_caseTable deleteRowsAtIndexPaths:indexPathsToDelete withRowAnimation:UITableViewRowAnimationTop];
    }
    self.openSectionIndex = NSNotFound;
     //ExNSLog(self, _cmd);
}

推荐答案

是的我也面对这种类型问题，做一件事只是删除页脚视图。

Yes i also face this type of problem,do one thing just remove footer view.
