Невозможно заполнить идентификатор проекта в URL задачи

В моем окне выбора есть три компонента: проекты, задачи и подзадачи. Мое требование - при выборе проектов я хочу отобразить задачи, соответственно назначенные идентификатору проекта и аналогично подзадаче. Я получил идентификатор проекта, и я не могу добавить этот идентификатор проекта в URL-адрес задачи, чтобы загрузить соответствующие задачи. Вот мой код ниже

NSArray *projectNames;
NSArray *taskNames;
NSArray *subtaskNames;
NSArray * projID;
NSArray * taskID;
NSArray * subtskID;
@synthesize lblProjects;
@synthesize lblTasks;
@synthesize lblSubTasks;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        lblProjects.text =  [[NSString alloc] init];
    }
    return self;
}
- (id)init
{
    // since we don't wanna re-implement allocation and instantiation for every
    // initializer, we call the 'designated initializer' with some default values,
    // in this case the default nibName and bundle are nil.
    return [self initWithNibName:nil bundle:nil];
}

    [super viewDidLoad];

    //NSLog(@"%@",myArrayString);
    //NSLog(@"%@",myTaskArrayString);
    lblProjects.text = [NSString stringWithFormat:@"%@",myProjectArrayString];
    //lblProjects.hidden = YES;
    lblTasks.text = [taskNames objectAtIndex:[pickerView selectedRowInComponent:1]];
    //lblTasks.text = [NSString stringWithFormat:@"%@", myTaskArrayString];
    lblSubTasks.text = [subtaskNames objectAtIndex:[pickerView selectedRowInComponent:2]];
}

Проще говоря, я хочу загрузить URL-адрес задачи с помощью идентификатора проекта

Заранее благодарим Киран Кумар
