Transforming UISearchbar - ios

Question

I have a search-bar with tableView below that search bar. I want to go full screen when the user tap search-bar for searching. But i am unable to set the frame to the origin of the UISearchBar.
i doing it in this way.
-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
[ [UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
[self.topBarView setHidden:YES];
[UIView animateWithDuration:1.0
delay:0.0
options:0
animations:^{
[self.searchBar setFrame:CGRectMake(0.0,0.0, self.searchBar.frame.size.width,
self.searchBar.frame.size.height )];
}
completion:^(BOOL completion){
}];
[self.searchBar setNeedsDisplay];
}
}
I am hiding all the views above the search-bar and i am setting the origin to 0,0
In the second image the top bar disappears but search-bar stays on its place. It should go at the top.
If somebody can identify the problem it will be great.
I am also using auto-layout does this make cause any problem?

Answer 2

Try this.
Add a search Bar & searchDisplay Controller to your controller.
UISearchBar *searchBar;
UITableView *tableView;
UISearchDisplayController *searchController;
// Create table view
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain];
_tableView.delegate = self;
_tableView.dataSource = self;
_tableView.backgroundColor = [UIColor whiteColor];
_tableView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
[self.view addSubview:_tableView];
// Create search bar
_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.view.bounds.size.width, 44.0f)];
_searchBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
_searchBar.delegate = self;
[self.view addSubview:_searchBar];
[_searchBar sizeToFit];
// Create search controller
_searchController = [[UISearchDisplayController alloc] initWithSearchBar:_searchBar contentsController:self];
_searchController.searchResultsDataSource = self;
_searchController.searchResultsDelegate = self;
_searchController.delegate = self;
Then you can perform this operation so that searchBar becomes responder & shows Keyboard.
[_searchBar becomeFirstResponder];
Hope that helps.
