如何将数据插入 NSMutableArray 内的 NSMutableDictionary 内的 NSMutableArray？

Question

我有一个包含多个 NSMutableDictionary 对象的 NSMutableArray，每个字典中都有一个 NSString 和一个 NSMutableArray。

我的问题是我需要根据字符串匹配找到正确的字典，找到后将一个对象插入到发现字符串匹配的同一字典中的 NSMutableArray 中，我只能在第一次完成这项工作当数组为空时，因为在那之后我无法匹配正确的字符串：

这是我到目前为止尝试过的方法，我尝试使用包含对象，但这不会让我进入数组中的字典，所以我被卡住了

NSMutableArray *variantOptions = [[NSMutableArray alloc] init];    

for (NSDictionary *variant in variantInfo) {
  NSMutableDictionary *variantOption = [[NSMutableDictionary alloc] init];
  NSMutableArray *variantOptionValues = [[NSMutableArray alloc] init];

  NSString *name = variant[@"name"];
  NSString *value = variant[@"value"];

  if(variantOptions.count > 0) {
  // Need to loop through the array until  name isEquaToString variantOptionName and when true insert value into variantOptionValuesArray in that same dict and if not exists create a new dict and insert in array
  } else {
     [variantOptionValues addObject:value];
     [variantOption setObject:name forKey:@"variantOptionName"];
     [variantOption setObject:variantOptionValues forKey:@"variantOptionValues"];
  }
  [variantOptions addObject:variantOption];
}

for (NSDictionary *variant in variantInfo) {
    NSString *name = variant[@"name"];
    NSString *value = variant[@"value"];

    BOOL found = false;
    for (NSMutableDictionary *v in variantOptions) {
        if (v[@"name"] isequalToString:name]) {
            NSMutableArray *values = v[@"variantOptionValues"];
            [values addObject:value];
            found = true;
            break;
        }
    }

    if (!found) {
        // name was not found
        NSMutableDictionary *variantOption = [[NSMutableDictionary alloc] init];
        NSMutableArray *variantOptionValues = [NSMutableArray alloc] init];

        [variantOptionValues addObject:value];
        [variantOption setObject:name forKey:@"variantOptionName"];
        [variantOption setObject:variantOptionValues forKey:@"variantOptionValues"];
        [variantOptions addObject:variantOption];
     }

}
