I am trying to implement the JASidePanels in my project using storyboard. You can see my storyboard over here.
The problem is that I don't see the button in the navigationbar to reveal the leftpanel. In my RootViewController I've this in code.
-(void) awakeFromNib
{
[self setLeftPanel:[self.storyboard instantiateViewControllerWithIdentifier:#"leftViewController"]];
[self setCenterPanel:[self.storyboard instantiateViewControllerWithIdentifier:#"centerViewController"]];
[self setRightPanel:[self.storyboard instantiateViewControllerWithIdentifier:#"rightViewController"]];
self.shouldResizeLeftPanel = YES;
self.shouldResizeRightPanel = YES;
[self setRightFixedWidth:300.0f];
[self setLeftFixedWidth:300.0f];
}
I've followed the steps that they say on the github page.
Also when I try to embed the RootviewController inside a navigationController. It is showing the navigationBar but not the barbutton item.
Any help on this ?
Embed your center UIViewController in storyBoard into UINavigationController, for example:
Select UIViewController on StoryBoard
Select Xcode menu item Editor - Embed In - Navigation Controller
Select new UINavigationController's Identity Inspector (Alt-Command-3)
Give unique name to StoryBoard ID e.g. myCenterController
Use that name to create center panel
[self setCenterPanel:[self.storyboard instantiateViewControllerWithIdentifier:#"myCenterController"]];
So you don't actually set viewController as centerPanel, but a navigation controller containing your viewController.
Well, I'm using swift 2.2 and I couldn't either see the navigation button.
I'm using storyboards; so I created:
MainViewController -> this is going to be the main container
LeftMenuViewController -> this is the left menu
ProductsViewController -> this is going to be inside MainViewController
So in MainViewController, I set up my VC as follows:
self.leftPanel = self.storyboard?.instantiateViewControllerWithIdentifier("LeftMenuViewController") //for left menu and
self.centerPanel = UINavigationController.init(rootViewController: (self.storyboard?.instantiateViewControllerWithIdentifier("ProductsViewController"))!)
Adding UINavigationController.init will solve the problem, and you will see the navigation button in the center panel.

Here is the scenario
Create new project Tabbed Application. Add new controller, TestViewController with XIB file, in the XIB file just add one button with text "TestViewControllerButton".
If I create a button in FirstViewController, and add an action to go to TestViewController, the button in XIB file is displaed.
TestViewController* vc = [[TestViewController alloc] init];
[self presentViewController:vc animated:YES completion:nil];
The problem is when I add TestViewController to tab controller (index 2, start from 0), it does not show the XIB (I mean, the button does not displayed).
Here are my steps. I add UIViewController in Tab Controller, then change the class to TestViewController in Identity Inspector. Then add Tab Bar Item to TestViewController and link it to Tab Bar Controller, so when the last tab is clicked, it linked to TestViewController. But the problem is, the button in the XIB is not displayed (I add the button in TestViewController.xib).
Yeah, off course I can add the button directly in Main.storyboard in my TestViewController, but the idea is I want to manage the UI in TestViewController XIB, and the main.storyboard just load the view in TestViewController image.
Ok, I add some screenshot to make understand. This screen runs well when I do programmatically, run in UIViewController (code above - self presentViewController:vc animated:YES completion:nil).
When I run from Tab
The setting I think is already correct (since it runs well in UIViewController)
Already set file owner to the TestViewController
Already bind the outlet
Thanks!
I think you are using the ViewController of size Inferred , Change it to iPhone 4 inch in Attribute Inspector (Simulated Metrics -> Size and set the button frame acc. to that .
Hope this help :)
Of course it will not show the controls. See, you are using two different view controllers at these places. In the xib, you have actually added your button and hence when an instance of your testViewController is created from the xib, it has the button and its associated action with it. However, in the case when you add a viewController in your storyboard and set its class to be that of TestViewController, all you are doing is setting the class type of the new view controller to be TestViewController. But you are not providing any information by which the storyboard can know that it has to create the new instance of testViewController from the image saved in its XIB. So it just crates a new view controller of type TestViewController, using its image from inside the storyboard (without the button in it).
So to get your view controller from the xib you will have to override initWithCoder: method inside your TestViewController implementation and return an instance of your viewController from the XIB. Something like:
- (instancetype)initWithCoder:(NSCoder *)aDecoder {
return [self initWithNibName:nil bundle:nil];
}
i am using manual navigation on button click from one viewcontroller to another
nextpage *np = [[nextpage alloc]init];
[self.navigationController pushviewController:np animated:YES];
I included nextpage class on the viewcontroller in storyboard. But in this case the elements added via drag and drop are not visible while if i add manual elements via code they are visible from nextpage on navigating. Please help !
and If I add navigation from a button through a storyboard, in that case both coded elements and storyboard elements are visible. !
Try this.
Pass a identifier to your view controller in storyboard.
nextpage *np = [self.storyboard instantiateViewControllerWithIdentifier:#"your identifier"];
[self.navigationController pushviewController:np animated:YES];
Content you've added in the storyboard will only appear if you load that view controller from the storyboard. By simply alloc/initing a new view controller you're losing all of the information you've added in the storyboard.
You can create a segue from a view controller to another one (i.e. not from a specific button) if you want to manually push, just use performSegueWithIdentifier, or you can add an identifier to the view controller and use instantiateViewControllerWithIdentifier to create your VC from the storyboard.
first of all give storyboard id to viewcontroller then add following code
Nextpage *nextPage = [self.storyboard instantiateViewControllerWithIdentifier:#"NextpageIdentifier"];
[self.navigationController pushviewController:nextPage animated:YES];
The root View View controller is Navigation controller and its first level is a TabViewController.One of the tab item is a TableViewController.
Here is the relationship:
However the navigation bar overlap the table view:
I have also set simulated metrics,So what can be the problem??
Thanks for any help.
Simulated metrics are just that, simulated. They do not actually apply to the compiled product.
To fix this, I find it easiest to set the edgesforextendedlayout with the various values of edge values. Usually all but the top.
The rootViewController should be the UITabBarController. Follow this code:
1.Make the UITabBarController the rootViewController in the application delegate or in your main.storyboard set it as the initial View Controller.
2.In the UITabBarController.m place this code there to create the UINavigationController with a UIViewController embeded inside of it.
//Inside UITabBarController.m
- (void)viewDidLoad {
[super viewDidLoad];
UIViewController *vc = [[UIViewController alloc]init];
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:vc];
self.viewControllers = #[navCon];
}
Get rid of the navigation controller in the beginning and, instead, embed the tableviewcontroller inside a navigation controller.
(Select the view controller -- Click "editor" > "embed in" > "navigation controller").
Make sure the tab bar controller is the root view controller as well
This will also fix the overlapping issue
I have a tab bar controller with a button like so:
- (void) addButtonPressed:(UIButton *) sender
{
[sender setBackgroundColor:[UIColor regularColor]];
PostViewController *post = [[PostViewController alloc] init];
[self.navigationController pushViewController:post animated:YES];
}
This code runs but the PostViewController is never shown and the tab bar controller remains.
How do I get to push to a new controller?
The NavigationController was created and StartViewController was add as rootController.
Then in StartViewController I have:
TabBarController *tab = [[TabBarController alloc] init];
// Presentation
[self presentViewController:tab animated:NO completion:nil];
in tab bar you need to create separate Navigation Controllers.
Suppose there are 3 tabs A, B and C. All the three tabs have functionality of navigation from one view to another. than you need to create three separate Navigation controllers eact pointing to Tab A, B and C. In this way you can navigate to any class within the specific Tab.
Check out this link for more details.
Hope this will help you. Happy coding :)
You may need to embed your tab bar controller within a navigation controller, In your storyboard click on your tabbarController so that it is highlighted with all the blue lines and then go to Editor in Xcode choose embed IN> UINavigationController ..If you want to do it programatically then in your AppDelegate where you setup your Window just Use This::
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:tabBarController];
navigationController.toolbarHidden=YES;
navigationController.navigationBarHidden=YES;
self.window.rootViewController =navigationController;
if you are using .xib then you have to use NSBundle to load nib
if you are using storyboard then you need to use prepareForSegue to pass on data or just display it out
I have a problem with switching views. I'm using a simulator with xcode 4.2
Storyboard contains:
NavigationController (initial view controller)
UIViewController which has relationship with the navigation controller
UIViewController (paired with my custom class: ViewEntryImageController) which hasn't got any relationship. Contains a button, a bottom toolbar with some toolbar button.
User come into the UIViewController, where he can see a ScrollView and in ScrollView some images.
Images has a gesture:
UITapGestureRecognizer *recognizer=[[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(openEntryImage)];
[image addGestureRecognizer:recognizer];
[recognizer release];
The openEntryImage function:
(IBAction)openEntryImage
{
ViewEntryImageController *controller=[[ViewEntryImageController alloc]initWithNibName:nil bundle:nil];
controller.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:controller animated:YES];
[controller release];
}
When I try to tap the image, the openEntryImage works as well (the effect is correct), but I don't see my ViewEntryImageController view and my buttons, I'm only see a black window.
I try to put a NSLog line into the ViewEntryImageController viewDidLoad function, and it works, so what is the black window and where is my view controller?
When I try to use pushViewController, on the new view I found a navigation toolbar with a back button, but no other controls.
I tried another version, I created a UIViewController class, but now with a xib file. I used it instead of ViewEntryImageController and it works. Why?
I want to use this controller in storyboard too.
The ViewEntryImageController class by itself has no information about how to build the dialog. But you can instantiate your view controller on your own from the storyboard:
UIStoryboard *myStoryboard = [UIStoryboard storyboardWithName:#"StoryboardFileName" bundle:nil];
ViewEntryImageController *controller = (ViewEntryImageController *)[myStoryboard instantiateViewControllerWithIdentifier:#"ViewEntryImage"];
This assumes a storyboard name of StoryboardFileName and that the view entry image controller has an identifier of ViewEntryImage set in the view properties (Attributes inspector, section "View Controller").
Try it like this :
ViewEntryImageController *controller=[[ViewEntryImageController alloc]initWithNibName:#"ViewEntryImageController" bundle:nil];
If you don't use .nib names but rather use storyboards, it's a bit harder. Create a segue from the controller to the ViewEntryImageController controller by holding ctrl and dragging from one view to the other. Click this segue and give it an identifier.
Then use the [self performSegue:#"identifier"]; function to present the next view.
