Iphone 通过选择UITableView行调用新视图时出错

根据在UITableView中选择的行，我在调出特定的ViewController时遇到一些问题。我有一个表，它包含3个部分，每个部分有4行

当选择一行时，我将其设置为为为每行调用一个新视图，因此根据选择的行，总共需要调用12个视图。问题是，只调用前4个视图，当我点击第5行时，它会显示一个新视图，但它会调出第一个视图

我已使用以下代码设置UITableView

carbData = [[NSArray alloc] initWithObjects:@"What Are Carbs?",@"Why Do I Need Carbs?",@"Simple Vs. Complex",@"Fun Five Facts",nil];
    proteinData = [[NSArray alloc] initWithObjects:@"What is Protein?",@"Why Do I Need Protein?",@"Complete Vs. Incomplete",@"Fun Five Facts",nil];
    fatData = [[NSArray alloc] initWithObjects:@"What Are Fats?",@"Why Do I Need Fats?",@"Saturated Vs. Unsaturated",@"Fun Five Facts",nil];
    [self setTitle:@"Nutrition Table"];

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 3;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.carbData count];
    return [self.proteinData count];
    return [self.fatData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];

    if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:SimpleTableIdentifier] autorelease];
    }   
    if(indexPath.section == 0)
        cell.text = [carbData objectAtIndex:indexPath.row];
    if(indexPath.section == 1)
        cell.text = [proteinData objectAtIndex:indexPath.row];
    if (indexPath.section == 2)
        cell.text = [fatData objectAtIndex:indexPath.row];
    return cell;
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
    if(section == 0)
        return @"Carbohydrates";
    if (section ==1)
        return @"Protein";
    else if (section ==2)
        return @"Fats";
}

然后，当选择某一行时，我使用以下代码确定要调用哪个视图

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


        if ([[carbData objectAtIndex:indexPath.row] isEqual:@"What Are Carbs?"]) {
            CarbsView1 *controller = [[CarbsView1 alloc] initWithNibName:@"CarbsView1" bundle:nil];
            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }
        if ([[carbData objectAtIndex:indexPath.row] isEqual:@"Why Do I Need Carbs?"]) {
            CarbsView2 *controller = [[CarbsView2 alloc] initWithNibName:@"CarbsView2" bundle:nil];
            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }
        if ([[carbData objectAtIndex:indexPath.row] isEqual:@"Simple Vs. Complex"]) {
            CarbsView3 *controller = [[CarbsView3 alloc] initWithNibName:@"CarbsView3" bundle:nil];
            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }
        if ([[carbData objectAtIndex:indexPath.row] isEqual:@"Fun Five Facts"]) {
            CarbsView4 *controller = [[CarbsView4 alloc] initWithNibName:@"CarbsView4" bundle:nil];
            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }
        if  ([[proteinData objectAtIndex:indexPath.row] isEqual:@"What is Protein?"]) {
            ProteinView1 *controller = [[CarbsView4 alloc] initWithNibName:@"ProteinView1" bundle:nil];
            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }

该应用程序编译和构建得很好，一切都按照我的意愿运行，但是当我查看使用的标题时，当我尝试并选择“What is Protein？”时，会在第一条if语句中调出“What is Carbs？”的视图

任何帮助都将不胜感激

“什么是蛋白质？”见第1节第0行。“什么是碳水化合物？”在第0节第0行。请注意，您的didSelectRowAtIndexPath方法不会在任何地方检查节号。因此，当点击第1节第0行时，第一条if语句返回true。我想你想要的东西更像：

if (indexPath.section == 0) {
    if(indexPath.row == 0) {
        //present appropriate view controller
    } else if (indexPath.row == 1) {

    } else if (indexPath.row == 2) {

    } ...
} else if (indexPath.section == 1) {
    if (indexPath.row == 0) {

    } else if (indexPath.row == 1) {

    } ...
} ...

你就在这一秒丰富了我的生活。这非常有效，我知道是这样的，但我不知道如何实施规则。多谢各位
