删除tableview的section遇到crash：The number of rows contained in an existing section after the update
来源：互联网 发布：linux syslog server 编辑：程序博客网 时间：2024/05/29 18:50
原因：删section必须用deleteSections。 删row必须用deleteRowsAtIndexPaths。
另外，删了后，数据源需要相应地删，否则数据不一致，crash
- (void)ignore:(NSInteger)sectionIdx
{
[_tableView beginUpdates];
//[_tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
[_tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIdx]
withRowAnimation:UITableViewRowAnimationFade];
[_arrOnlineFiles removeObjectAtIndex:sectionIdx];
[_tableView endUpdates];
}
