tableHeaderView UISearchBar not showing - ios

Question

I have added a UISearchBar programatically to my UITableView, it was showing perfectly fine untill I decided to add an offset to my UITableView to hide the UISearchBar when the view is loaded. I would like help displaying it again.
This is what my code looks like.
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.contentOffset = CGPointMake(0.0f, 44.0f);
mySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
mySearchBar.autocorrectionType = UITextAutocorrectionTypeNo;
mySearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
mySearchBar.keyboardType = UIKeyboardTypeAlphabet;
mySearchBar.delegate = self;
self.tableView.tableHeaderView = mySearchBar;
// Create the search display controller
UISearchDisplayController *searchController = [[UISearchDisplayController alloc] initWithSearchBar:mySearchBar contentsController:self];
searchController.searchResultsDataSource = self;
searchController.searchResultsDelegate = self;
I am not really sure where to go to from here.

This code will work in both iOS6 and iOS7.
Note that in iOS7 you will loose transparency of NavigationBar
if ([self respondsToSelector:#selector(edgesForExtendedLayout)]) {
self.edgesForExtendedLayout = UIRectEdgeNone;
}
[self.tableView setContentOffset:CGPointMake(0, mySearchBar.frame.size.height)];
If you want to save default transparency in iOS7 use this code:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if ([self respondsToSelector:#selector(edgesForExtendedLayout)]) {
[self.tableView setContentOffset:CGPointMake(0, -20)];
}
else {
[self.tableView setContentOffset:CGPointMake(0, mySearchBar.frame.size.height)];
}
}
