I've created a new XCode project using the SplitViewNavigator template. One of the MasterViewController's navigationItems should present a configuration ViewController (fullScreen on iPhone, popup on iPad).
This config controller has been created in a separate storyboard (Filter.storyboard).
In this storyboard I dragged a ViewController on the stage and embedded it in a Navigation Controller (Editor -> Embed In -> Navigation Controller) because the config itself consists of different screens the user can go through.
The NavigationController has been given a StoryBoard ID "FilterNavController".
I've done this several times in other applications, so this does work. Unfortunately, I can't get it working with the SplitViewNavigator template.
Here is how I try to open the filter controller once the button has been tapped, nothing special about it;
UIStoryboard *filterBoard = [UIStoryboard storyboardWithName:#"Filter" bundle:nil];
UINavigationController *filterNavController = [filterBoard instantiateViewControllerWithIdentifier:#"FilterNavController"];
UIViewController *vc = [filterNavController.viewControllers objectAtIndex:0];
[self.navigationController presentViewController:vc animated:YES completion:nil];
self is the MasterViewController.
From my uneducated point of view, I don't see any reason why this wouldn't work. As I said, it does in other (non SplitViewNavigator template) applications.
The error message I'm getting is the following:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modally an active controller <UINavigationController: 0x7f9bab61a700>.'
No idea what the heck is going on here but it already cost me half a day.
Interestingly, when I just create a UIViewController on the Filter.storyboard and set its StoryBoardID, the ViewController will get presented. However, I need it to be embedded in a UINavigationController.
Any help would be highly appreciated!
For the sakes of completeness, the following method works nicely for instantiating ViewControllers from a Storyboard.
Instead of creating a UINavigationController on the Storyboard, just create the ViewController(s) and embed them in a UINavigationController on code.
UIStoryboard *myBoard = [UIStoryboard storyboardWithName:#"MyStoryboard" bundle:nil];
MyViewController *menuController = [myBoard instantiateViewControllerWithIdentifier:#"MyViewController"];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myController];
[self presentViewController:navController animated:YES completion:nil];

I am handling push on alert to jump/open a view in story board like this from delegate
UIStoryboard * storyboard = [UIStoryboard storyboardWithName:#"Main_iphone4" bundle:nil];
ChatViewController *scvc = (ChatViewController *)[storyboard instantiateViewControllerWithIdentifier:#"ChatViewController"];
[self.window.rootViewController presentViewController:scvc animated:YES completion:nil];//not working show nothing while it works to jump using simple xib views.
and if i use
self.window.rootViewController =scvc;//it works but i need to get back on back button which causes it to get back in blank screen.
How to jump to a view controller using storyboard on handling push from delegate.
NOTE: The jump view have a back button,which need to dismiss the view too.
NOTE APP IS NOT NAVIGATION BASED
How can to go back to previous view programmatically without UINavigationController, because all examples that I have found use UINavigationController ?
I am making view for sending feedback and I would like to use this view in many more apps.
If I use UINavigationController than app need to have UINavigationController to use my view for sending feedback.
Is this possible to do and how ?
This is code how I show my view for sending feedback:
- (IBAction)showFeedbackView:(id)sender {
WOC_FeedbackViewController *feedbackView = [[WOC_FeedbackViewController alloc] init];
[self presentViewController:feedbackView animated:YES completion:nil];
}
Use this to go back
[self dismissViewControllerAnimated:YES completion:nil];
Depending on what your project works (Storyboards or XIB) you can use presentViewController. But thats when you keep a reference on your last viewController's identifier.
If you know the ID of your viewController NSString *yourID;
1) Init your viewController
For storyboard
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:yourID];
For XIB
UIViewController *vc = [UIViewController alloc]initWithNibName:yourID bundle:nil];
2) Presenting your ViewController
[self presentViewController:vc animated:YES completion:nil];
P.S This is a way to do this, but you should use navigationController because you can keep memory of a viewController on stack so when you need to access it again, you can access it faster. In other words, UINavigationController is applied in every iOS Application you see on App Store.
In Swift, you can use following line of code to go back to previous view controller without navigation controller:
self.dismissViewControllerAnimated(true, completion: nil)
My app is is designed to handle the PDF files. Whenever user opens a PDF file I would like to redirect the him/her to appropriate ViewController.
I tried several different approaches and I noticed interesting behavior.
Whenever I reference the navigation controller using window everything works fine:
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
[navigationController pushViewController:_importer animated:YES];
But when I use storyboard
UIStoryboard *st = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UINavigationController * nav =(UINavigationController *)[ st instantiateInitialViewController ];
[nav pushViewController:_importer animated:YES];
It doesn't work. Why?
instantiateInitialViewController creates a new instance of the initial view controller of your storyboard. At that point, its view is not part of the view hierarchy. The pushing works just fine, I'm sure, but since the navigation controller isn't on screen, you won't see the new view controller get pushed.
I am working on an app in xCode 5. This is a first at using the Storyboard. My app starts with a simple username/password login screen. Upon successful login, I want to programmatically switch from this login View to my Tab Bar Controller with the tab index set at 1.
I do not have a custom class for my UITabBarController. I can build one if need be. Can someone help get me started or point me in the right direction?
Funny how typing out the question can help you solve it. Here is the code I used in case someone has the same issue in the future
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
UITabBarController *vc = (UITabBarController *)[storyboard instantiateViewControllerWithIdentifier:#"UITabBarController"];
[self presentViewController:vc animated:YES completion:nil];
[vc release];
If you have only one storyBoard in your project then you can also use simply
self.storyboard
The best way to do this is to set your rootviewController to tabBarcontroller as soon as you authenticate the user. Here is how you can do this in swift.
let tabBarController = self.storyboard?.instantiateViewControllerWithIdentifier("TabBarController") as! UITabBarController
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = tabBarController
Where TabBarController is the storyboard id of your tab bar controller. It could be anything whatever name you have given it.
In storyboard; drag a segue from your ViewControllers button (or File's Owner to connect a method) to your TabBarVC. Choose modal style and animation if you wish.
Add a new custom class for UITabBarController and assign it to TabBarVC in storyboard.
In it's implementation file; put self.selectedIndex = 1;
I am having a problem with this.
In my root view controller I am having a textfield & one button. I am giving a condition like if i entered 0 in textfield then only it should move to next view.
upto here it is working correctly. But now here is problem. Here I am having one button & given navigation to third view controller for that button. here i am getting error as
Terminating app due to uncaught exception 'NSGenericException', reason: 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'
image ref: http://img12.imageshack.us/img12/8533/myp5.png
and i am giving action for button in first view as below
- (IBAction)Submit:(id)sender {
if([tf.text isEqual:#"0"])
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
SecondViewController *vc2 = [storyboard instantiateViewControllerWithIdentifier:#"SecondViewControllerID" ];
[self presentViewController:vc2 animated:YES completion:NULL];
}
}
Go To:
Editor--> Embed In --> Navigation Controller, to add Navigation Controller to your initial view
After looking at your screenshot, you either need to
Push your SecondViewController onto the existing navigation controller's stack instead of presenting it modally OR
You need to embed your SecondViewController in another navigation controller and then create and present that navigation controller modally from your SamplesViewController
Either way, SecondViewController needs to be embedded in a navigation controller before you can use Push Segues from it
Either embed your view controller in a Navigation controller or if there is a Navigation controller in the story board mak it the initial view controller
I also faced same problem. My problem was I was using model segue style (rather that push) for one before the current controller because of that I think it broke the Navigation chain before already.
Embed your view controller in a UINavigationController is a good option if there is no UINavigationController in the storyboard. Otherwise you can select the UINavigationController and select the root view controller in the inspector pane, then drag it to the UIViewController you want to use as root. the screenshot is as below:
I solved this by creating a custom UIStoryboardSegue between the UINavigationController and the destination view controller:
-(void) perform
{
assert([self.sourceViewController isKindOfClass:[MyNavigationController class]]);
MyNavigationController *launchController = (MyNavigationController *) self.sourceViewController;
[launchController setViewControllers:#[self.destinationViewController] animated:YES];
}
Try this. It works for me.when you set root view controller to first view and use self.presentViewController ,controller move to next view but instance of navigation controller is only for first view,third view required navigation instance so use self.navigationController instead of presentViewController.
NSString * storyboardName=#"Main";
UIStoryboard *storybord=[UIStoryboard storyboardWithName:storyboardName bundle:nil];
SecondViewController *vc=[storybord instantiateViewControllerWithIdentifier:#"SecondViewControllerID"];
[self.navigationController pushViewController:vc animated:YES];
