I want to push to another view from a popoverview. For that purpose I had a taken navigation controller to that popover. And also its working fine.
The problem occurs in the second view. To allow the user to send an email i show a mail composer. But i am getting two navigation controllers.
Here is the code for the first popoverview:
SettingsVC *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"SettingsVC"];
vc.delegate = self;
UINavigationController *naviCon = [[UINavigationController alloc]initWithRootViewController:vc];
self.settingsPopover = [[UIPopoverController alloc] initWithContentViewController:naviCon];
CGRect frame = CGRectMake(974.f, 36.f, 0, 0);
self.settingsPopover.popoverContentSize = CGSizeMake(300, 250);
[self.settingsPopover presentPopoverFromRect:frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
When I needed something similar, I called the MFMailComposeViewController from the ViewController which calls the PopoverController (the parent ViewController) and also included the delegate ect in that ViewController.
I defined a protocol in the ContentViewController of the PopoverViewController which informs the parent ViewController when it needs to call the MFMailComposeViewController.
All worked perfectly without a problem... hope that helps

I am trying to display a simple iPad popover which contains a navigationController with a tableView.
popover -> navigation controller -> view controller -> table view.
I do need the navigationController because on touching the cells I want to push another viewController (within that same popover).
Without the navigation controller, everything is fine.
But as soon as I put the viewController inside a navigationController, the tableView stops responding (didSelectRow doesn't get called). I suppose something is wrong with my delegates but I just can't work it out.
. The navigationController responds fine (I can hit a button I have in the top bar)
. The buttons that are IN the cells respond fine.
. If I touch down and hold on a cell it gets highlighted, but not selected.
UPDATE: I just found out that if I hold the cell down for at least a second, the delegate is called when I release it. any less than that and it is never called...???
Here is the code use:
ModalViewController* controllerWithTable = [[self storyboard] instantiateViewControllerWithIdentifier:identifier];
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:controllerWithTable];
UIPopoverController* popover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
popover.delegate = self;
[popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
If you are using a popoverController to show a table view, you don't need to embed it in a navigation Controller, Instead make a different Viewcontroller with the table view and just shoe that inside a popover controller .I used it somewhat like this..
Make a global reference for UIPopoverController in your app delegate,
//in your Appdelegate.h file declare this
#property(strong, nonatomic) UIPopoverController *popOverForTableView;
Now In the controller which you want to show the PopOver view use this,
TableViewCOntroller* popoverContent = [[TableViewCOntroller alloc] init];
NSString *identifier=#"tableVC"
popoverContent =[[UIStoryboard storyboardWithName:#"Main"
bundle:nil]
instantiateViewControllerWithIdentifier:identifier];
popoverContent.preferredContentSize = CGSizeMake(330, 280);
AppDelegate *appDelegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];
appDelegate. popOverForTableView = [[UIPopoverController alloc]initWithContentViewController:popoverContent];
appDelegate.popOverForTableView.delegate = self;
appDelegate.popOverForTableView.backgroundColor=[UIColor blackColor];
[appDelegate.popOverForTableView presentPopoverFromRect:self.date.frame inView:self.view permittedArrowDirections:(UIPopoverArrowDirectionUp) animated:YES];
You can dismiss it accordingly…,…see if this Helps..
Ok I found the answer there: https://stackoverflow.com/a/18159463/3562952
The tableView was not irresponsive, it was deceptively responding only after a 1-3 seconds hold down.
I had a tap responder on the parent view that was capturing the tap. I am now removing it when displaying the popover and putting back in on dismissal.
I was googling for the wrong symptoms :)
I am trying to implement UIPopoverController. I have seen some sample code but still confused on how to connect the popover view controller to storyboard. Help please.
if (!patientPopover) {
UIStoryboard * storyboard = [UIStoryboard storyboardWithName:#"MyStoryboard" bundle:nil];
MyViewController * addPacientController = [storyboard instantiateViewControllerWithIdentifier:#"MyViewController"];
UINavigationController * myNavController = [[UINavigationController alloc] initWithRootViewController:MyViewController];
patientPopover = [[UIPopoverController alloc] initWithContentViewController:myNavController];
patientPopover.delegate = self; // optional
}
[patientPopover presentPopoverFromBarButtonItem:yourInstanceBarButtonItemOrMethodArgumentAttachedToTheBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
It's good to have your popover in an instance variable so that you avoid allocating it each time you press the button. I am using here presenting the popover from a UIBarButtonItem, but you can also present it from any view, like :
[patientPopover presentPopoverFromRect:yourView.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
You don't need to visually see the actual popover in the storyboard or nib file, because it is only a container. You just need to see what goes inside it, and that is the view controller, and obviously, you can do that.
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 have a login view which I want to display in popover. I am doing this from code as below:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:[NSString stringWithFormat:#"MainStoryboard_%#", isIPAD ? #"iPad" : #"iPhone"] bundle:NULL];
UIViewController *navCtrl = [storyboard instantiateViewControllerWithIdentifier:#"LoginViewController"];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navCtrl];
popover = popover;
popover.delegate = self;
popover.popoverBackgroundViewClass = [PopoverBackground class];
self.popover = popover;
[self.popover presentPopoverFromRect:((UIButton *)sender).bounds
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionDown
animated:YES];
But the popover never shows. But the weird thing is viewdidload and viewwillappear for loginview are called. And on again clicking on the view calls the popover delegate method didDismissPopover.
Though it works fine when presented from a popover segue.
I do not want to create a segue because login might be called from different locations and I want to keep this code separate.
Has anyone before faced such issue.
Solved it!!
Turned out I was giving the arrow direction as UIPopoverArrowDirectionDown and the rect to show was not proper. Changed the rect to (100, 500, 10, 10), and voila! Everything is perfect.
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)
