Unable to populate the Project ID into task URL - ios

Question

There are Three components in my Picker view projects, tasks and Sub tasks. My requirement is when selecting the projects I want to Display the tasks respectively whcih are assigned to the project ID and similarly with the sub task. I got the project ID and I dont how to append this project ID to Task URL to load the respective tasks. Here is my code Below
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];
}

Simply Speaking I want to load the Task URL with the Help of Project ID
Thanks in Advance
