iphone - UItextField within UISearchbar failing after iOS 7 upgrade

Question

I have a UITextField for the UISearchBar which this was working until iOS 7 upgrade and now it fails at this line: UITextField *textfield=(UITextField*)[[searchBar subviews] objectAtIndex:1];

any idea how to fix this? thanks

    // search bar
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 190.0, 44.0)];
searchBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
UIView *searchBarView = [[UIView alloc] initWithFrame:CGRectMake(90.0, 0.0, 230.0, 44.0)];
searchBarView.autoresizingMask = 0;
searchBar.delegate = self;

searchBar.layer.borderColor=[UIColor whiteColor].CGColor;

UITextField *textfield=(UITextField*)[[searchBar subviews] objectAtIndex:1];

[searchBarView addSubview:searchBar];

self.navigationItem.titleView = searchBarView;
