Creating a UISearchBar and UITableView inside a UIView - ios

Question

Disclaimer: I'm something of an iOS n00b. I have a navigation-based app -- i.e., in my AppDelegate, I create the nav frame:
self.navigation_controller = [[UINavigationController alloc] initWithRootViewController:home_view_controller];
self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
self.window.rootViewController = navigation_controller;
self.window.makeKeyAndVisible;
Inside the frame of my home view, I want a search bar, then the scrollable table view. So, I wrote this:
- viewDidLoad{
(HomeView*)home_view = [[HomeView alloc] init];
self.view = home_view
self.view.backgroundColor = [UIColor whiteColor]
(UITableView*)self.table_view = [UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];
self.table_view.bounds.origin.y += 44;
self.table_view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.table_view.dataSource = self;
self.table_view.delegate = self;
[self.view addSubview:self.table_view];
search_frame = self.view.bounds;
search_frame.origin.y = 48.0;
search_frame.size.height = 48.0;
self.search_bar = [[UISearchBar alloc] initWithFrame:search_frame)];
[self.view addSubview:self.search_bar];
}
The table view displays fine, but occupies all the space below the navigation bar. I want to have the navigation bar, then immediately below it the search bar, followed by the table view. At the point of viewDidLoad, the UITableView does not yet have a non-zero bounding rect and I expect that's part of the problem. Additionally, I've specified UIViewAutoresizingFlexibleHeight in my autoresizingMask when I really want it glued against the search bar -- again, I believe this may be part of the problem.
What have I misunderstood here?
Thanks

Steve,
Try following changes:
1) Set tableview's frame using:
CGRect targetRect = CGRectMake(0, 48, self.view.frame.size.width, self.view.frame.size.heigth);
(UITableView*)self.table_view = [UITableView alloc] initWithFrame:targetRect style:UITableViewStylePlain];
2) Add following autosize mask also:
// This value will anchor your table view with top margin
UIViewAutoresizingFlexibleBottomMargin
3) Set searchbar's frame to following rect frame:
CGRecttMake(0, 0, self.view.frame.size.width, 48);

What I would do, is just add the UISearchBar as the first UITableView header.
(method: tableView:viewForHeaderInSection:)
