【中文标题】NSInternalInconsistencyException 原因：\'无效更新：第 0 节中的行数无效\'【英文标题】：NSInternalInconsistencyException reason: 'Invalid update: invalid number of rows in section 0'NSInternalInconsistencyException 原因：'无效更新：第 0 节中的行数无效' 【发布时间】：2014-06-25 06:06:23 【问题描述】：我有一个名为 dummyData 的数组数组，但在将数组 cmets 的计数作为表中的行数返回时遇到问题。
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
NSArray *commentsArray=[[dummyData objectAtIndex:section] valueForKeyPath:@"comments"];
NSLog(@"Comments: %d", [commentsArray count]);
if (section == didSection)
return [[[dummyData objectAtIndex:section] valueForKeyPath:@"comments"] count];
return 0;
它给了我这个错误：
由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'无效更新：第0节中的行数无效。更新后现有节中包含的行数（3）必须等于行数更新前包含在该节中的行数 (0)，加上或减去从该节插入或删除的行数（2 插入，0 删除），加上或减去移入或移出该节的行数（0 移入, 0 移出）。'
这是我的数组：

我的问题是，如何返回每个部分的 cmets 数量。因为 cmets 数组的内容数量或计数不同。
【问题讨论】：
NSLog(@"Comments: %d", [cmetsArray count]);返回 5,3,2 和 3 我尝试在 numberOfRowsInSection 中返回 2 并且成功了。但我没有得到预期的结果。它为所有部分返回 2 行。我也尝试返回 1 或 3，但都犯了与上面发布的相同的错误。 【参考方案1】：修复了问题：
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
NSArray *commentsArray=[[dummyData objectAtIndex:section] valueForKeyPath:@"comments"];
NSLog(@"Comments: %d", [commentsArray count]);
if (section == didSection)
return [[[dummyData objectAtIndex:section] valueForKeyPath:@"comments"] count];
return 0;

这与您在问题中发布的代码完全相同以上是关于NSInternalInconsistencyException 原因：'无效更新：第 0 节中的行数无效'的主要内容，如果未能解决你的问题，请参考以下文章
