The basic design of app storyboard goes like this:
Top Level#1
Navigation Controller --> View Controller (Front) contains button "Show Master"
Next Level#2
Navigation Controller --> View Controller (Master) --> push --> View Controller (Detail)
When I run the app in simulator, Front View Controller page appears.
Requirement: On "Show Master" button click, I wanted the control focused to Master. When something done here, either show Detail view Controller or swing back to Front view Controller. How to code this from Front.M and Master.M.
Setup: iOS 6.x, XCode 5.x
Note: Below code exists in Front.M but it does not work, brings up Master page in black
vwMaster *vc = [[vwMaster alloc] init];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];
Any thought?
It looks like you're most of the way there, but that vwMaster has no layout information associated with it. One way to provide this would be to create a .xib file with the same name as your view controller class (i.e. vwMaster.xib) and set the xib file's owner to vwMaster. Your existing code should then work.
It seems like you're using Storyboard, however, in which case you have several options:
The easiest option. In Storyboard, ctrl-drag from the button in the Front view controller to the Master view controller. select a modal segue type.
Create a modal segue between the Front and Master view controllers in Storyboard by ctrl-dragging between them, give the segue an identifier (e.g. "vwMaster") in the attributes inspector and trigger the segue in code:
[self performSegueWithIdentifier:#"vwMaster" sender:self];
Give the vwMaster view controller itself an identifier in the identity inspector in storyboard and present that as you were before:
vwMaster *vc = (vwMaster *)[self.storyboard instantiateViewControllerWithIdentifier:#"vwMaster"];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];
Regardless of the route you choose, you're likely to want use the delegate pattern to dismiss your view controller. For this and more, I suggest you read the relevant apple Docs:
https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html
if you use navigationcontroller y u no use push and pop instead presenting viewController?
Thanks knellr.
I have been playing with different flows. I am able to goto view by calling
[self performSegueWithIdentifier:#"name" sender:self] - provided name'm.
Also have strong code handling - in cases where data to be passed out
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
//NSLog(#"prepareForSegue: %#", segue.identifier);
if ([[segue identifier] isEqualToString:#"name"])
{
}
}

There is problem in view hierarchy. Here is flow of my app.
When app starts View Controller "A" is Visible. After that storyboard "B" is loaded through "StoryBoard Reference (Push)" ,Where another navigation controller is present and Home screen is loaded. On Click of Menu button in Home screen Side panel is visible.
Now When i click on side panel menu items view Controller "B" is pushed. This View Controller is Pushed Under Home screen and is not Vsible.
Help View contoller is visible under Home controller. I want Help View Controller should come on top of Home controller.
I dont understand what issue is coming..
Any Help will be appreciated..
If you are pushing view controller from side panel shows in image, will never push because it is not in navigation controller.
the answer depends on how you showing your side menu but from assumptions
what you need to do is to set root view controller or keep reference of navigation controller and push from there
If you are presenting side menu then it is not on navigation controller so you should first dismiss this side menu and on the completion of it you should push new view controller (says B or Help). I am writing my code snippet that i am using in my project for demonstration,
- (IBAction)settingClick:(id)sender {
SettingViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:#"settingsScreen"];
[self dismissViewControllerAnimated:NO completion:^{
[self.vc.navigationController.navigationController pushViewController:svc animated:YES];
}];
}
Above method push setting view controller on current navigation controller after dismissing side menu
Now important thing is self.vc this is the object of previous viewcontroller (Home controller in your case i think) on which side menu was presented.
So my SideMenuViewController has a property like,
#property (nonatomic,strong) UIViewController *vc;
which i am setting with self from previous view controller (in your case from Home view controller) something like,
SideMenuViewController *smvc = [self.storyboard instantiateViewControllerWithIdentifier:#"sideMenu"];
smvc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:smvc animated:NO completion:^{
smvc.vc = self;
}];
And i have used [self.vc.navigationController.navigationController pushViewController:svc animated:YES]; i.e. two navigation controller to push because i have two navigation controller in my view hierarchy to push this new view controller.
You can manage that as per your setup that how many navigation controller you have !!
Hope this will help :)
After digging a lot, I found solution for this.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Home" bundle: nil];
RootController *someViewController = [storyboard instantiateViewControllerWithIdentifier:#"RootController"];
[self.navigationController pushViewController:someViewController animated:YES];
I have set another navigation controller as root ViewController of the window and it worked for me.
Thanks.
I added a Navigation Controller to my storyboard and it appears like so:
Now in the table view controller, I gave the TableViewController a storyboard id and class to a TableViewController Controller
When I run my app, I don't see the Navigation Bar at the top. This has been extremely frustrating and can't find a solution anywhere. PLEASE HELP
To get to the scene, someone clicks a button and this code runs and it goes to my Table View Controller:
UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:#"Storyboard" bundle:nil];
LHFileBrowser *LHFileBrowser = [storyBoard instantiateViewControllerWithIdentifier:#"FileBrowser"];
[self.navigationController pushViewController:LHFileBrowser animated:YES];
[self presentViewController:LHFileBrowser animated:YES completion:nil];
The error is in your code.
If you want to (modally) present a view controller when the user presses a button, you need to present the navigation controller (which will contain the table view controller), not the table view controller itself.
Right now, you're presenting the view controller, which won't show it being embedded in a navigation controller.
Also, you're mixing up two different approaches, by trying to push a view controller onto a navigation controller stack, and also presenting the view controller.
Code Sample:
Here's what you apparently mean to do:
UIStoryboard *storyboard = self.storyboard;
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"MyNavigationControllerID"];
LHFileBrowser *rootViewController = [navigationController topViewController];
// Configure your LHFileBrowser view controller here.
rootViewController.someProperty = ...;
// Modally present the embedded view controller
[self presentViewController:navigationController animated:YES completion:nil];
If you want to change the presentation or transition style, you can set those details in your storyboard.
You didn't explain why you had to programmatically add buttons, but Storyboard segues would have instantiated and presented an embedded view controller for you, without you having to have done it in code.
The more you can do in Storyboard, the less code you have to maintain, support, and update, and the more likely your app will still work properly when a new SDK is released.
Update:
The better way to do this is to let Storyboard do it for you, by adding a segue from the button to the navigation controller that you want to present.
Ok, I'm still pretty new; so, please bear with me.
I'm creating a custom app for a friend that displays a list of work orders in a table view. Clicking on a work order brings them to a detail view. In the detail view, there is a button that uses a push to present another screen called completion view. From the completion view, they click a button that uses the following code to present a nib for signature capture.
SigScreenViewController *sigScreenViewController=[[SigScreenViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil];
[self presentViewController:sigScreenViewController animated:YES completion:nil];
The signature screen uses: https://github.com/jcmontiel/SignatureViewExample for capturing the signature and does it well. I have a button that completes the transaction and sends it back to the table view list.
My problem is that I cannot create a button that will return me to the completion view in the storyboard.
I've tried the following in a button:
[self dismissViewControllerAnimated:YES completion:nil];
or
[self.navigationController popViewControllerAnimated:YES];
I'm open for any suggestions on how I can do it.
Thanks in advance!
Have you tried having the UIViewControllers embedded in a navigation controller ?
Are you pushing from a UIViewController in UIStoryboard to a NIB file?
If so check out this sample project that pushes from storyboard to a NIB:
// in a navigation controller
// to load/push to new controller use this code
// this will be next screen
DetailsViewController *detailsViewController = [[DetailsViewController alloc ]init];
[self.navigationController pushViewController:detailsViewController animated:YES];
// to go back or pop controller use this
// now it will send back to parent screen
[self.navigationController popViewControllerAnimated:YES];
In my app, I need to go to another UIViewController with a button click, but when I did it in the new UIViewController it displays only what I set programmatically.
I used:
NewSubject *NewS = [[NewSubject alloc] initWithNibName:nil bundle:nil];
[self presentViewController:NewS animated:YES completion:nil];
"NewSubject" is the UIViewController I need to go too, however I want the computer to display also the stuff I set by the Storyboard.
Have you set in the Storyboard, in the NewSubject View Controller, in the third tab (Show Identity Inspector) the StoryBoard ID?
You should set it to some name, such as "NewSubject" and use it as follow:
NewSubject *NewS = [self.storyboard instantiateViewControllerWithIdentifier:#"NewSubject"];
[self.navigationController pushViewController:NewS animated:YES];
I want the computer to display also the stuff I set by the Storyboard.
If you're using a storyboard, -initWithNibName:bundle: is the wrong method to use. You can use UIStoryboard's -instantiateViewControllerWithIdentifier: method to create a new view controller that's defined in a storyboard, but the more typical approach is to have your button trigger a segue between the two view controllers.
Try this:
While editing your storyboard, control-drag from your button to the new view controller. A popup menu should appear that lets you choose how you want to transition between the view controllers -- push (push the new controller onto the top of the navigation stack), modal (present the view controller modally), etc. Pick the appropriate one.
In simple cases, you're done -- there's no need to write any code just to get the transition to happen. The segue takes care of creating the new view controller and performing the transition for you. However, you often want to pass some data from the existing view controller to the new one. If that's the case, implement -prepareForSegue:sender: in the existing view controller -- this method gives you a chance to pass whatever data you need. It'll look something like this:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// It doesn't hurt to check that it's the segue that you expect
if ([segue.identifier isEqualToString:#"MySegueIdentifier"]) {
NewViewController *newVC = segue.destinationViewController;
// This is your chance to set properties or call methods to pass data to the new view controller
newVC.foo = self.foo;
newVC.bar = self.bar;
}
}
I just started to use Storyboard in Xcode. I have a starting view that has some buttons inside. Is there a way to load a special view when a button is clicked?
I only found this workaround:
-(IBAction)loadRegistration:(id)sender {
// load registration controller
UIStoryboard *storyboard = self.storyboard;
RegisterController *svc = [storyboard instantiateViewControllerWithIdentifier:#"RegisterController"];
[self presentViewController:svc animated:YES completion:nil];
}
You don't need any code to load a new view. You just control-drag from the button to the controller you want to present, and choose the segue type. If the controller with the button is in a navigation controller you can choose push or modal, if it's not, then you want to choose modal.
The way you did it seems ok. You can also connect the current View Controller to the one you want to present with a segue in the Interface Builder (ctrl + drag). When the button is tapped, you would call [self performSegueWithIdentifier:#"segue identifier"];. Of course, you set the id of the segue in the IB.
Even more simpler would be to connect the button with the new View Controller in IB (also ctrl+drag). This way you won't even need the IBAction.
