我将数据从 plist 加载到 uitableview，如下所示：

- (void)viewDidLoad {
    [super viewDidLoad];


    NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    NSString *path = [[documentPaths lastObject] stringByAppendingPathComponent:@"data.plist"];

    NSMutableDictionary *resultDic = [[NSMutableDictionary alloc] init];
    NSMutableArray *resultArray = [[NSMutableArray alloc] init];
    NSDictionary *myDict = [NSDictionary dictionaryWithContentsOfFile:path];


    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"purpleKey"])
    {
        NSArray *purple = [myDict objectForKey:@"Purple"];
        [resultArray addObject:@"Purple"];
        [resultDic setValue:purple forKey:@"Purple"];
    }
    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"orangeKey"])
    {
        NSArray *orange = [myDict objectForKey:@"Orange"];
        [resultArray addObject:@"Orange"];
        [resultDic setValue:orange forKey:@"Orange"];
    }


    self.tableData = resultDic;
    self.sectionsTitle = resultArray;

}

titleForHeaderInSection

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
   return [sectionsTitle objectAtIndex:section];
}

我的 plist 结构

在此处输入图像描述

我的问题是：如何手动设置紫色标题和橙色标题的标题而不更改 plist 文件中的名称？像这样：紫色 = 1 类，橙色 = 2 类

编辑

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
   return sectionsTitle.count;
}


- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
   return [sectionsTitle objectAtIndex:section];
}



- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    int num = [[tableData objectForKey:[sectionsTitle objectAtIndex:section]] count];

    if (num > 3) {
        num = 3;
    }

    return num;
}


// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    NSDictionary *dict = [[tableData objectForKey:[sectionsTitle objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];

    cell.textLabel.numberOfLines = 1; 
    cell.textLabel.font = [UIFont systemFontOfSize:11]; 
    cell.textLabel.text = [NSString stringWithFormat:@"%@ - %@", [dict objectForKey:@"Name"], [dict objectForKey:@"Address"]];

    if ([dict objectForKey:@"Address"] == (NULL)) {
        //do nothing
    }

    return cell;
}

从您的代码的外观来看，部分标题来自resultsArray，您正在使用常量字符串 Orange 和 Purple 填充它们。

您可以将不同的常量字符串放入该数组中，除非我遗漏了什么。

所以，而不是

[resultArray addObject:@"Orange"];

利用

[resultArray addObject:@"Category 1"];
