我有一个名为dummyData的数组数组，我在将数组注释中的计数作为表格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。更新后的现有部分中包含的行数（3）必须等于行数在更新（0）之前包含在该部分中，加上或减去从该部分插入或删除的行数（插入2个，删除0个）以及加入或减去移入或移出该部分的行数（0移入，0搬出去。'
这是我的阵列：

我的问题是，如何返回每个部分的评论数量。因为评论数组有不同数量的内容或计数。
答案 0 :(得分：1)
修正了问题：
-(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;
}
