我在表格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。如果由于动画当时任何单元格部分可见,我的应用程序在 [_Mytableviewobject endUpdates] 行崩溃;
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”
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]];
}
