iOS 7 doesn't show cancel button of search bar in navigation bar

Question

In an app that\'s supposed to run on iOS 6 and iOS 7, the cancel button of the search bar embedded in the navigation bar is not shown anymore if the app is run on iOS 7. On iOS

Answer 1

In my opinion this is a bug. Heres my workaround. It's not perfect but it works both on iOS 6&7. On iOS7 the searchbar textfield slides over the cancel button while it's fading out and on iOS6 the textfield width expansion isn't animated.

@interface FTViewController ()
@property(nonatomic, strong) UISearchBar *searchBar;
@end

@implementation FTViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.searchBar = [[UISearchBar alloc] init];
    self.searchBar.delegate = self;

    if (NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_6_1) {
        // iOS 6.1 and older (only tested on 6.1)
        [self.searchBar sizeToFit];
        self.searchBar.backgroundImage = nil;
    }

    self.navigationItem.titleView = self.searchBar;
}

-(void)cancelBarButtonItemClicked:(id)sender
{
    [self searchBarCancelButtonClicked:self.searchBar];
}

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
    [searchBar resignFirstResponder];
    [self.navigationItem setRightBarButtonItem:nil animated:YES];
}

-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{
    UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelBarButtonItemClicked:)];
    [self.navigationItem setRightBarButtonItem:cancelBtn animated:YES];

    return YES;
}
