Objective c 奇怪的错误：UITableView中的insertRowsAtIndexPaths与NSInternalInconsistencyException一起崩溃

对于我在下面编写的示例应用程序中收到的

nsinternalinconsistenceexception

，我已经搜索了一个更合适的答案，但仍然没有找到答案。目标是为tableView的每个部分的顶行创建展开/折叠功能。现在我尝试实现扩展部分，这适用于第0节中的第0行。一旦用户点击另一节中的第0行，就会出现此错误：

返回更改后节中正确的行数

为了获得上述异常，我在代码中做错了什么

这是接口文件：

#import <UIKit/UIKit.h> 
#import <QuartzCore/QuartzCore.h>

@interface MasterViewController : UITableViewController {
  NSMutableArray *rowsInSection;
  NSMutableArray *cellForRow;

@property (nonatomic,strong) NSMutableArray *rowsInSection;
