I try to integrate this sdk ( http://whamcitylights.com/sdk/#iOS )
in a my storyboard application,
My problem is in the point 4.
NOTE: That code assumes you are using a UINavigationController. If necessary you may need to add code to create and initialize it.
Here is an example:
I have UIPageViewController with four different UIViewController
and I need to change the last one with a UINavigationController
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = ... // however you create your view controller...
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navCon.navigationBarHidden = YES;
self.window.rootViewController = navCon;
[self.window makeKeyAndVisible];
return YES;
}
I need to do this in a storyboarded-based application
Thank you all!
Use it:
[self.navigationController pushViewController:nextViewController animated:YES];

App content doesn't rotate if I use UINavigationController in my app. Only status bar orientation changes.
This is my didFinishLaunchingWithOptions method.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"Main"
bundle:nil];
SpecificViewController *control=[sb instantiateViewControllerWithIdentifier:#"specific"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:control];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; [self.window setRootViewController:navigationController];
return YES;
}
I dont understand why I am getting this result.
FOUND IT
Finally, I found a solution. But I don't understand why.
this is my didFinishLaunchingWithOptions method.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window.rootViewController =nil;
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"Main"
bundle:nil];
SpecificViewController *control=[sb instantiateViewControllerWithIdentifier:#"specific"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:control];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
return YES;
}
And this is viewDidLoad method of SpecificViewController.
- (void)viewDidLoad {
[super viewDidLoad];
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
self.navigationItem.title=#"The Title";
}
And I set "View controller-based status bar appearance" property to NO in plist file.
It is working now but I don't understand what do all these mean and why.
I don't think the answer you've accepted is the correct one here, I guess if it works for you that's great but it still looks wrong to me.
The reason rotation wasn't working was because you're using Storyboards which automatically create a UIWindow. Then in your application didFinishLaunching method you are alloc'ing a new UIWindow. Only the first UIWindow (created by your storyboard) will receive the rotation notifications, which is why you only noticed the status bar rotating and not your views.
The solution is to remove the following lines from your didFinishLaunchingWithOptions method:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
Your rootViewController will also be set in the storyboard, there's no need to set it again in code.
This works for me, try:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"Main"
bundle:nil];
SpecificViewController *control=[sb instantiateViewControllerWithIdentifier:#"specific"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:control];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
return YES;
}
add this to SpecificViewController.m
- (BOOL)prefersStatusBarHidden
{
return NO;
}
set "View controller-based status bar appearance" property to YES and remove "Main" from Main Interface options.You don't need to use setStatusBarHidden method.
I am new to iOS. And I want to use navigation controller in my application but I have no any idea how to do it. So can any one guide me step by step for creating navigation in my application.
In appDelegate.h
#property (strong, nonatomic) UINavigationController *navController;
and set the delegate UINavigationControllerDelegate and synthesise object in appDelegate.m
now,
appDelegate.m
you can set navigation controller in didFinishLaunchingWithOptions method
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
frstVwCntlr = [[firstViewController alloc] initWithNibName:#"firstViewController" bundle:nil];
self.navController = [[UINavigationController alloc] initWithRootViewController:self.frstVwCntlr];
self.window.rootViewController = self.navController;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
In the above code , your firstViewController is set to UINavigationController and UINavigationController added to UIWindow like
self.window.rootViewController = self.navController
Hope this may help you
If you want to create everything programmatically you have to do it in AppDelegate.
But if you don't want to do it programmatically, then just select the ViewController in Storyboard then select menu options:
Editor > Embed In > Navigation Controller
You can creat UINavigationController in Appdelegate and set your first viewcontroller on it.
So for creating a UINavigationController programatically without using storyboards, go to your app delegate and do the following. Create two properties, window and viewController
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor=[UIColor clearColor];
self.viewController = [[YourFirstViewController alloc] initWithNibName:#"YourFirstViewController" bundle:nil];
UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:self.viewController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
// Override point for customization after application launch.
return YES;
}
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
ImageViewController2 *dealVC = (ImageViewController2 *)[storyboard instantiateViewControllerWithIdentifier:#"ImageViewController2"];
[self.navigationController pushViewController:dealVC animated:YES];
where ImageViewController2 is a class name
Here is the code that you should write in app delegate.
UIViewController *vc=[[UIViewController alloc]initWithNibName:#"vc1" bundle:nil];
UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
view.backgroundColor=[UIColor redColor];
[vc setView:view];
self.navme=[[UINavigationController alloc]initWithRootViewController:vc];
self.window.rootViewController = self.navme;
For Swift 3.0, using filter:
let desiredController = self.navigationController!.viewControllers.filter { $0 is YourController }.first!
self.navigationController!.popToViewController(desiredController, animated: true)
I'm adding the following code to my application in order to navigate back and forth from a quicklook view.
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self rotateView];
nav = [[UINavigationController alloc] initWithRootViewController:self];
[window addSubview:[nav view]];
[window makeKeyAndVisible];
[[self navigationController] setNavigationBarHidden:YES];
This code is run in my main ViewController viewDidLoad function. My application runs in landscape but this window and navigation bar loads in portrait mode. My application doesn't have a statusBar so some code I've found doesn't work. I get an error if I try to check and listen for status bar orientation notifications.
I'm looking for a way to allow this navigation view to set it's orientation based on the apps current orientation.
If I understand your question Your above code should be placed in didFinishLaunchingWithOptions not in viewDidLoad in the AppDelegate and the initialization of MainViewController should be there also.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.mainViewController = //init your MainViewController;
navigationController = [[UINavigationController alloc] initWithRootViewController:(UIViewController*)viewController];
[window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
I want to make a simple navigation control application in which I have two view controllers(ViewController and ViewController2). I have a button in ViewController and when I press the button, I want it to go to the other view. The problem is that button doesn't work. I also tried the UIViewController, but didn't work in that way neither.
The AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
ViewController *vc1 = [[ViewController alloc]init];
UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:vc1];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
[self.window addSubview:nav.view];
return YES;
}
The ViewController.m
- (IBAction)myButton:(id)sender {
ViewController *vc2 = [[ViewController alloc]init];
[[self navigationController]pushViewController:vc2 animated:YES];
}
Thanks in advance for your help
if you use storyboard import in your ViewController1 the ViewController2 and give a storyboard ID to it "view2":
ViewController2 *vc2 = (ViewController2 *)[self.storyboard instatiateViewControllerWithIdentifier:#"view2"];
[self.navigationController pushViewController:vc2 animated:YES];
I'm developing an iOS 4 application with latest SDK and XCode 4.2.
I'm using an UINavigationController and I don't want to show Navigation Bar. To do that, I use this code on AppDelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil] autorelease];
}
else
{
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil] autorelease];
}
navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navController.navigationBar.hidden = YES;
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
But, this line, navController.navigationBar.hidden = YES; doesn't work. I don't see navigation bar on first view controller, but I see it on others views.
Any clue?
I have achieved this doing the following:
Setting navController.NavigationBar.hidden = YES; in AppDelegate, after alloc it.
Setting [navController setNavigationBarHidden:YES animated:YES]; on viewWillAppear: on every viewController that I pust to navController.
try
[navController setNavigationBarHidden:YES animated:NO]
The doc is here.
I think that the navigationBar has to be set hidden on the view, not on the controller.
