Custom Navigation Transitions on iOS 7, how to manage the keyboard? - uiview

Question

TabBarController.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
PlaylistViewController *playlistViewController = [[PlaylistViewController alloc] init];
UIViewController *otherViewController = [[UIViewController alloc] init];
UINavigationController *playlistNavigationController = [[UINavigationController alloc] initWithRootViewController:playlistViewController];
playlistNavigationController.delegate = self;
self.viewControllers = #[playlistNavigationController, otherViewController];
playlistNavigationController.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemDownloads tag:kTabBarTagPlaylist];
playlistNavigationController.tabBarItem.title = #"Playlist";
otherViewController.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemMore tag:kTabBarTagOther];
playlistNavigationController.navigationBar.tintColor = [UIColor redColor];
}
- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController animationControllerForOperation:(UINavigationControllerOperation)operation fromViewController:(UIViewController *)fromVC toViewController:(UIViewController *)toVC {
if (operation == UINavigationControllerOperationPush) return [[FadeTransition alloc] init];
else if (operation == UINavigationControllerOperationPop) return [[SlideTransition alloc] init];
return nil;
}
PlaylistViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor redColor];
UIBarButtonItem *storeBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Store"
style:UIBarButtonItemStylePlain
target:self
action:#selector(test)];
self.navigationItem.leftBarButtonItem = storeBarButtonItem;
UIBarButtonItem *currentlyPlayingButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Now playing"
style:UIBarButtonItemStylePlain
target:self
action:#selector(test)];
self.navigationItem.rightBarButtonItem = currentlyPlayingButtonItem;
self.navigationItem.title = #"Playlist";
self.playlistTableViewController = [[PlaylistTableViewController alloc] initWithStyle:UITableViewStylePlain];
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
searchBar.placeholder = #"Search";
searchBar.delegate = self;
self.playlistTableViewController.tableView.tableHeaderView = searchBar;
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
self.searchController.delegate = self;
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
[self addChildViewController:self.playlistTableViewController];
[self.view addSubview:self.playlistTableViewController.view];
self.playlistTableViewController.view.frame = self.view.bounds;
self.playlistTableViewController.view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
[self.playlistTableViewController didMoveToParentViewController:self];
}
FadeTransition.m
- (NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext
{
return 0.5;
}
- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
/* view controllers */
UIViewController *fromVC = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
UIViewController *toVC = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
/* views */
UIView *containerView = [transitionContext containerView];
[containerView addSubview:fromVC.view];
[containerView addSubview:toVC.view];
/* settings */
toVC.view.alpha = 0.0f; /* not visible at start */
[UIView animateWithDuration:[self transitionDuration:transitionContext]
delay:0
options:UIViewAnimationOptionTransitionNone
animations:^{
toVC.view.alpha = 1.0f; /* 100% visible at the end */
}
completion:^(BOOL finished) {
[fromVC.view removeFromSuperview];
[transitionContext completeTransition:YES];
}];
}
This is how it looks like:
When I touch one of the results, a new UIView gets pushed and animated by FadeTransition.
The keyboard automatically gets slided down, but I need to leave the keyboard opened (it should stay behind), how can I do it?
