Answer 1

In Objective C:

- (void)viewDidLoad {
    [super viewDidLoad];

    // Setup your SearchViewController here...
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    // Will show Cancel button in White colour 
    [[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:[UIColor whiteColor]];

    // searchController.active = YES;   // This is not necessary

    // set SearchBar first responder inside Main Queue block
    dispatch_async(dispatch_get_main_queue(), ^{
        [self->searchController.searchBar becomeFirstResponder];
    });
}
