IOS -- 调用deleteRowsAtIndexPaths:withRowAnimation:崩溃的问题

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];

NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0.  The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1),

[dataArr removeObjectAtIndex:indexPath.section];//这句是肯定要有的
[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]  withRowAnimation:UITableViewRowAnimationRight];
[tableView endUpdates];

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:0]] withRowAnimation:UITableViewRowAnimationNone]；

调用deleteRowsAtIndexPaths:withRowAnimation:withRowAnimation:
后如果tableView:numberOfRowsInSection返回的行数不是删除前－1则会crash,同样删除最后一行导致numberOfSectionsInTableView返回值跟调用前不一样而crash。解决方法，调用deleteRowsAtIndexPaths:withRowAnimation:时判断是不是该section最后一行，如果时则同时调用deleteSections:indexSetWithIndex:withRowAnimation:
