Iphone 无法使用正确的计数和数据填充tableview节/行。从plist文件

我在项目的最后几天遇到了一点小麻烦。问题是，我试图用从用户创建的可编辑plist文件读取的部分填充我的表视图

当前，未分组的单元格填充良好。这些细胞甚至彼此相邻。 但是，我想做的是为每个组创建部分（按标题）

所以第一节都有第一节的标题。第二节也会这样做。 我得到的是所有组中所有相同的标题（单元格）

我已经为标题创建了部分，并在标题中显示这些标题

我认为我的问题是如何填充RowsFlosections和cellForRows

这里有几个代码剪贴

我将数据从plist拉入一个数组，然后在ViewDidDisplay中像这样对其进行排序

self.accessDataArray = [[NSMutableArray alloc]initWithContentsOfFile:appDelegate.pathToUserCopyOfPlist];

NSSortDescriptor * descriptor = [NSSortDescriptor sortDescriptorWithKey:@"ProjectID" ascending:YES];
[accessDataArray sortUsingDescriptors:[NSArray arrayWithObject:descriptor]];

然后，我合并数组以删除重复的部分计数和标题，如下所示

mutset = [[NSMutableSet alloc] init ];

if ([accessDataArray count]>1) {

    for (i = 0; i < [accessDataArray count]; i++) {
        [mutset addObject:[[accessDataArray objectAtIndex:i]objectForKey:@"ProjectID"]];
        NSLog(@"mutable count = %d",[mutset count]);

       }
    }

    setToArray = [[NSArray alloc]initWithSet:mutset];
    NSLog(@" setarray count = %d",[setToArray count]);

    for (int m = 0; m < [mutset count]; m++) {
      NSLog(@"new array %@",[setToArray objectAtIndex:m]);
    }`

以下是应用程序生成的调试日志：

好的，我在原来的帖子里修改了密码。她为标题显示了正确数量的章节标题和标题。在每个部分中，我都有每个部分中数组中存在的对象数量（计数）。以下是应用程序使用当前设置生成的调试日志。也许这会有助于了解情况

假设您要取消对return1的注释//[设置阵列计数]；这可能会返回您拥有的“标题”（也称为节）的数量，在numberOfRowsInSection中，您希望返回作为参数传递给您的节的行数。确保在titleForHeaderInSection例程中返回NSString。

很抱歉代码的格式设置不确定为什么从numberOfSectionsInTable返回1，因此表中只有一个节。那么在numberOfRowsInSeciton中，我希望您使用section参数来确定有多少行，但是section参数没有在该方法中使用？好的，我在原始帖子中更改了代码。她为标题显示了正确数量的章节标题和标题。在每个部分中，我都有每个部分中数组中存在的对象数量（计数）。我不太确定您的问题——是数组的显示与数组结构不符，还是无法将数组加载到所需的结构中？是的，显示的单元格与部分不符。我想要的是第0节title=Main，那么只有标题为“Main”的对象才会存在于该节中。我得到的是所有对象填充所有部分。您必须在cellForRowAtIndexPath中进行筛选。基本上，系统会调用cellForRowAtIndexPath，并且您的代码会为系统提供适当的单元格（对象）。因此，将使用nsindepath调用您。index.xpath.section将告诉您必须为哪一节提供信息，而index.xpath.row将告诉您哪一行。因此，请检查cellforrowatinexpath中的indexath参数，并在返回的单元格中提供正确的信息。谢谢，这很有意义。现在只要你能把它打出来…（翻译成代码）
