I am attempting to present a UIPopoverController similar to the bookmark selector in Safari with the title above and the ability to go back and forward. I found this tutorial: http://mobiforge.com/designing/story/using-popoverview-ipad-app-development and have followed it, yet my navigation bar is not appearing like it should be. Instead, it is appearing like it is recessed in the popover controller and not actually part of the popover controller. Below is the code I have so far. Any help would be greatly appreciated.
Code:
- (IBAction)addAPrePlan:(id)sender
{
if (![self.preplanPopoverController isPopoverVisible]) {
// Initiate the popover controller
UITableViewController *pp = [[UITableViewController alloc] init];
pp.navigationItem.title = #"Add a PrePlan";
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:pp];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:nav];
popover.delegate = self;
self.preplanPopoverController = popover;
}
else {
// Dissmiss the popover
[self.preplanPopoverController dismissPopoverAnimated:YES];
}
// Present the popover controller
[self.preplanPopoverController presentPopoverFromBarButtonItem:self.addAPrePlanButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

I am updating an old app to the new adaptive size way of doing things and having difficulty getting a popover with a navigation controller to work.
My goal: I want to be able to open a popover from a button when the app is either compact and regular horizontal. The popover has a tableview and uses a navigation controller to push view controllers when the user touches a row on the table. I can get the popover to open correctly, but I can’t figure out who to make the pushes work.
Here’s the code that opens the popover:
OptionsController *vc = [[OptionsController alloc] initWithNibName:#"OptionsView" bundle:nil];
vc.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = [vc popoverPresentationController];
popover.delegate = self;
[self presentViewController:vc animated: YES completion: nil];
popover.permittedArrowDirections = UIPopoverArrowDirectionUp; // change as necessary
popover.sourceView = self.view;
CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]];
popover.sourceRect = popoverRect;
This code correctly opens a popover in either compact or regular size.
In the OptionsController’s didSelectRowAtIndexPath method, I have this(controllersArray is an array of UIViewControllers, each of which corresponds to a row in the table):
UIViewController *nextController = [self.controllersArray objectAtIndex: [indexPath row]];
[self.navigationController pushViewController:nextController animated:YES];
All this executes, but no push occurs, so the next view never appears.
I clearly am not understanding something about using the UIViewController’s navigationController, or how to install a navigationController to make this work. After three or four days of digging around to try to understand how to make this work, I'd appreciate any insights, or links to documentation about how to do this. Thanks in advance.
Crud - this has a very easy answer. Just took me thinking a different way and digging through Larcerax's comments. Here's how to make this work:
OptionsController *vc = [[OptionsController alloc] initWithStyle:UITableViewStylePlain];
vc.title = #"Options";
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController: vc];
nc.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = [nc popoverPresentationController];
popover.delegate = self;
[self presentViewController:nc animated: YES completion: nil];
popover.permittedArrowDirections = UIPopoverArrowDirectionUp; // change as necessary
popover.sourceView = self.view;
CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]];
popover.sourceRect = popoverRect;
The difference is that I create the UINavigationController in the usual manner...
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController: vc];
...set the navigationController's presentation style to popover, then get the popoverPresentationController from the navigationController - before I was doing those two methods on the UIViewController.
nc.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = [nc popoverPresentationController];
Finally, I present the navigationController:
nc.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = [nc popoverPresentationController];
This approach presents a popover, in compact and regular horizontal sizes, that contains navigation controller functionality: just what I wanted.
Thanks again to Larcerax whose answer wasn't what I needed, but made me re-think what I was doing in a different way. As usual, StackOverflow comes through.
Here's what you should try. I use about 10-40 navigation controllers per app for the apps I work on and I've had this same sort of issue, I've not used popovers, but I've subclassed the crap out of navigation controllers and view controllers to have encountered your same problem. The thing is that if you do this:
UIViewController * ff = [UIViewController new]
[self presnetViewController:ff ... blah blah blah
There is apparently NO navigation system attached to the modal view controller and therefore you can't navigate to anything else, you can only close the modal and move on. So, this is what I do to resolve this and it works everytime, well it works everytime for UIViewControllers, give it a shot
see the following, it's not for popovers, but the principle is the same:
NSHTermsOfServiceViewController * pvc = [NSHTermsOfServiceViewController new];
UIBarButtonItem * backBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"exit-button"] style:UIBarButtonItemStylePlain target:self action:#selector(backerPressed)];
NSHNavigationController * ssf = [[NSHNavigationController alloc] initWithRootViewController:pvc];
[[pvc navigationItem] setLeftBarButtonItem:backBarButtonItem];
[[self navigationController] presentViewController:ssf animated:true completion:nil];
NSHTermsOfServiceViewController <== is a subclass of another subclass of a UIViewcontroller, it's basically a UIViewController on steroids, that's all
NSHNavigationController is a UINavigationController that is subclassed and pumped up on steroids for animations
The flow is this:
create a viewController
create a new UINavigationController
Set the view controller you created in step 1 as the root view controller of the navigation controller created in step 2
present the NAVIGATION CONTROLLER, not the UIViewController, you can present this navigationController from a view controller like so ..
v
[self presentViewController:ssf animated:true completion:nil];
or you can present it from the current view controller's navigation controller which is what I prefer, like so:
[[self navigationController] presentViewController:ssf animated:true completion:nil];
Your code, modified, the only problem is that I don't know if you can present a UIPopOverViewController by rooting it inside a navigation controller
OptionsController *vc = [[OptionsController alloc] initWithNibName:#"OptionsView" bundle:nil];
UIPopoverPresentationController *popover = [vc popoverPresentationController];
UINavigationController * stuff = [[NSHNavigationController alloc] initWithRootViewController:popover];
stuff.modalPresentationStyle = UIModalPresentationPopover;
stuff.delegate = self;
[self.navigationController presentViewController:stuff animated: YES completion: nil];
popover.permittedArrowDirections = UIPopoverArrowDirectionUp; // change as necessary
popover.sourceView = self.view;
CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]];
popover.sourceRect = popoverRect;
Yep, my bad, doesn't work for popover, I just tried it
So, with that said, is it absolutely necessary to use a popover? Why are you using this and now just a UIViewcontroller that you reconfigure to look like a popover and then you have what you need?
Here's this, I just tried it with the Ipad simulator, and it allowed a push, just as it should have.
NSHLoginViewController * pvc = [NSHLoginViewController new];
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:pvc];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navController];
UIView * stuff = [[UIView alloc] initWithFrame:CGRectMake(50, 50, 1000, 1000)];
[self.view addSubview:stuff];
[popover presentPopoverFromRect:[[self contentView] nameField].frame inView:stuff permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
this: [[self contentView] nameField].frame is just a uitextfield, nothing special, that's all, and the method above presented the login viewcontroller, when I put in my credentials, I pressed log in and it pusehed the next viewcontroller as it normally would, there's probalby something wrong with the touches being intercepted by your uitableview or whatever, perhaps not, but this method did work for me.
I had an application in which I need to have a login or register system before the tab bar controller is added to the window, such as in Instagram.
I have added 5 navigation controllers (with view controller as its root) to the UITabBarController and then set it as the root of the window. Before that, I need to have another UINavigationController for the login system.
If I add that, how do I remove it before adding tab?
Another problem is that I also have to handle logging out, so I need to come back to it.
Can anybody help me with me how to do this?
I suggest to you loading Loginview From Delegate window as we did Normally. and from Logged Success its button click you set TabbarController like this:-
UIViewController *viewControllerPostalCode2 = [[cntrServices alloc] initWithNibName:#"cntrServices" bundle:nil];
UIViewController *viewControllerPostalCode3 = [[cntrInquiryViewController alloc] initWithNibName:#"cntrInquiryViewController" bundle:nil];
UINavigationController *navPostage1 = [[UINavigationController alloc] initWithRootViewController:viewControllerPostalCode2];
UINavigationController *navPostage2 = [[UINavigationController alloc] initWithRootViewController:viewControllerPostalCode3];
//
navPostage1.navigationBar.tintColor =DARK_BACKGROUNDNavigation;
navPostage2.navigationBar.tintColor =DARK_BACKGROUNDNavigation;
//
self.tabBarForServicesController = [[UITabBarController alloc] init];
self.tabBarForServicesController.delegate=self;
self.tabBarForServicesController.viewControllers = [NSArray arrayWithObjects:navPostage1,navPostage2,nil];
[self.navigationController pushViewController:self.tabBarForServicesController animated:YES];
I Done this type of Task using this method and at the Logged Out just poptoRootviewController work back to the Logged in Screen.
I have done this like adding my tabbarcontroller as rootViewController to UIWindow and in applicationbecomeactive delegate i present a controller with navigation controller like when required and simply dismiss the controller when authentication done
UIViewController *topViewController = [self.navController topViewController];
if (![topViewController isKindOfClass:[LGLoginViewController class]]) {
[self.navController popToRootViewControllerAnimated:YES];
self.navController = nil;
LGLoginViewController* loginView = [[LGLoginViewController alloc] initWithNibName:#"LGLoginViewController"bundle:nil];
if (!self.navController) {
self.navController = [[UINavigationController alloc] initWithRootViewController:loginView];
} else {
[self.navController initWithRootViewController:loginView];
}
self.navController.delegate = self;
[self.window.rootViewController presentModalViewController:self.navController animated:NO];
}
So I'm presenting a UIPopoverView like so:
if (self.BStatePopoverViewController == nil) {
RedStatePopoverViewController *settings =
[[RedStatePopoverViewController alloc]
initWithNibName:#"RedState"
bundle:[NSBundle mainBundle]];
UIPopoverController *popover =
[[UIPopoverController alloc] initWithContentViewController:settings];
popover.delegate = self;
self.BStatePopoverViewController = popover;
}
[BStatePopoverViewController setPopoverContentSize:CGSizeMake(320, 445)];
[self.BStatePopoverViewController presentPopoverFromRect:[sender bounds] inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Once the view is loaded in the popover, I have a button which I'd like to use to present a new UIViewController within the popover. I tried just presenting it as a modal view but this changes the parent view as opposed to the one in the popover:
PopupDischargeViewController * dischargeview = [[PopupDischargeViewController alloc] initWithNibName:#"PopupDischargeViewController" bundle:nil];
[self presentModalViewController:dischargeview animated:NO];
Any help as to how I do this would be much appreciated.
Thanks!
To change the view controller the popover should display once it's been initialized use UIPopoverController's method – setContentViewController:animated:
You could also add your RedStatePopoverViewController to a UINavigationController and use its methods – pushViewController:animated: and – popViewControllerAnimated: to navigate between view controllers
Hope this helps!
I'm trying to show a popover with a title, creating a root view controller and instantiating it with my viewController. But, when I show the popover, the content is not shown. Here is the code:
UIViewController *popContentViewController = [[sb instantiateViewControllerWithIdentifier:#"videosTutoriais"] init];
UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:popContentViewController];
_popover = [[UIPopoverController alloc] initWithContentViewController:controller];
_popover.delegate = self;
[popContentViewController release];
[controller release];
//dados.myPopoverController = popOverController;
[[self popover] presentPopoverFromRect:ancora.bounds inView:ancora permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Just to be more specific, the title of popover appears normally, but the content doesn't.
Just double check that popContentViewController is not nil. You have the identifier #"videosTutoriais" which looks like it might be a scanning error.
From your code, you are releasing the controller before you display in on the screen. Try releasing it after or in the dealloc method. If you are unsure about memory management. I suggest you try ARC instead to avoid silly errors and mistakes such as this.
The code looked like this:
sb = [UIStoryboard storyboardWithName:#"MainStoryboard_iPad" bundle:nil];
UINavigationController *controller = [[sb instantiateViewControllerWithIdentifier:#"navTutorial"] init];
_popover = [[UIPopoverController alloc] initWithContentViewController:controller];
[[self popover] presentPopoverFromRect:ancora.bounds inView:ancora permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[controller release];
I open a popOver with a view(DetailView) in a view(MapView). it works fine.
But in my detail view has a button(feedback).so i want to push the another view(feedbackform)on btton clicked.
I tried but nothing is Happened.
Can i push the view inside the popover?
My code is as follow:
// MapView.m
detailsView *popUp=[[detailsView alloc] initWithNibName:#"detailsView_ipad" bundle:nil];
popView = [[UIPopoverController alloc]initWithContentViewController:popUp];
popView.delegate =self;
[popView setPopoverContentSize:CGSizeMake(600, 500)];
[popView presentPopoverFromRect:control.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
//Detailview.m
-(IBAction)openFeedbackForm:(id)sender {
fbView = [[deatailsFeedback alloc]
initWithNibName:#"deatailsFeedback_ipad" bundle:nil];
[self.navigationController pushViewController:fbView animated:YES];
}
To achieve this your detailsView should be a Navigation controller with a root controller to the original detailsView.
This way when you pop the navigationController, you can perform push from your detailsView and that would only affect the popOver view
detailsView *popUpView=[[detailsView alloc] initWithNibName:#"detailsView_ipad" bundle:nil];
UINavigationController *popUpNavController = [[UINavigationController alloc] initWithRootViewController:popUpView];
popView = [[UIPopoverController alloc]initWithContentViewController:popUpNavController];
popView.delegate =self;
[popView setPopoverContentSize:CGSizeMake(600, 500)];
[popView presentPopoverFromRect:control.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
//Detailview.m
-(IBAction)openFeedbackForm:(id)sender {
fbView = [[deatailsFeedback alloc]
initWithNibName:#"deatailsFeedback_ipad" bundle:nil];
[self.navigationController pushViewController:fbView animated:YES];
}
If I understand your code correctly, openFeedForm IBAction method is in Detailview.m?
Meaning the first part of the code is in a different class than the one at the bottom?
If so, since Detailview itself is not in a navigationController, it will not push anything to its non-existant navigation controller.
What you want to do is have MapView push the new view in its navigationController.
Side note: since you are setting the delegate of the popUp in MapView as (self) the IBAction method should be defined in MapView
(This is assuming my first statement about understanding your code is correct)
