How to add the UIView into UIPopoverViewController
-(void) buttonAction:(id)sender {
//build our custom popover view
UIViewController* popoverContent = [[UIViewController alloc]
init];
UIView* popoverView = [[UIView alloc]
initWithFrame:CGRectMake(0, 0, 200, 300)];
popoverView.backgroundColor = [UIColor whiteColor];
popoverContent.view = popoverView;
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover =
CGSizeMake(200, 300);
//create a popover controller
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
//present the popover view non-modal with a
//refrence to the button pressed within the current view
[self.popoverController presentPopoverFromRect:popoverButton.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
//release the popover content
[popoverView release];
[popoverContent release];
}
This will add the view to your UIPopoverViewController

Are there examples of how to use UIPopoverController on iOS?
Try the below Code:
if (mycontroller == nil) {
MyController * viewController = [[MyController alloc] initWithNibName:#"ControllerView" bundle:nil];
mycontroller = viewController;
PopoverController = [[UIPopoverController alloc] initWithContentViewController:self.mycontroller];
PopoverController.delegate = self;
}
[PopoverController presentPopoverFromRect:CGRectMake(260, 120, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

Using UIPopovercontroller below ios8.0 in iphone working fine with this code. But in ios8 it display white screen.
Code :
pickerController = [[UIViewController alloc] init];
UIView *viewV = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 160)];
[viewV setBackgroundColor:[UIColor clearColor]];
popOverController = [[UIPopoverController alloc] initWithContentViewController:pickerController];
popOverController.popoverContentSize = CGSizeMake(150, 160);
[popOverController setDelegate:self];
CGRect ImageBtnFrame = [self.view convertRect:sender.frame fromView:self.view];
[popOverController presentPopoverFromRect:ImageBtnFrame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
Any alternative for ios8, need suggestion.
According to 2014 WWDC, in the 30 minute mark, the right answer is:
- (void) tapButton:(id) sender
{
MyViewControllerClass * vc = [[MyViewControllerClass alloc] init];
vc.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController * popOverController = vc.popoverPresentationController;
[popOverController setDelegate:self];
popOverController.sourceView = sender;
popOverController.sourceRect = ((UIButton*)sender).frame;
popOverController.permittedArrowDirections = UIPopoverArrowDirectionUp;
[self presentViewController:vc
animated:YES
completion:nil];
}
Notice that the accepted answer has some problems like:
Not setting the modalPresentationStyle
Presenting the UIPopoverPresentationController * instead of the UIViewController
Try to use the new iOS 8 API for popovers.
pickerController = [[UIViewController alloc] init];
UIView *viewV = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 160)];
[viewV setBackgroundColor:[UIColor clearColor]];
UIPopoverPresentationController *popOverController = pickerController .popoverPresentationController;
popOverController.popoverContentSize = CGSizeMake(150, 160);
[popOverController setDelegate:self];
popOverController.sourceView = self.view;
popOverController.sourceRect = sender.frame;
popOverController.permittedArrowDirections = UIPopoverArrowDirectionUp;
[self presentViewController:popOverController
animated:YES
completion:nil];
That will cause on iOS 8. So, I recommended to use following Github library.
https://github.com/skywinder/ActionSheetPicker-3.0 or you can write code base on iOS version.
if (OLDER_THAN_IOS_8) {
// Your regular code
pickerController = [[UIViewController alloc] init];
UIView *viewV = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 160)];
[viewV setBackgroundColor:[UIColor clearColor]];
popOverController = [[UIPopoverController alloc] initWithContentViewController:pickerController];
popOverController.popoverContentSize = CGSizeMake(150, 160);
[popOverController setDelegate:self];
CGRect ImageBtnFrame = [self.view convertRect:sender.frame fromView:self.view];
[popOverController presentPopoverFromRect:ImageBtnFrame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
} else {
// New Code that support iOS -8 using UIPopoverPresentationController
// Checkout #AndreasZ answer for the same
}
I'm writing an app that needs to spawn a popover in order to add a new note. To that end, I have something that does kind of the trick, however, I can't seem to adjust the size of the popover. This is how I'm spawning it:
UIButton* btn =sender;
UIViewController* fooTroller = [[UIViewController alloc] init];
CGRect rectFoo = CGRectMake(0, 0, 100, 100);
UIView* fooView = [[UIView alloc] initWithFrame:rectFoo];
[fooView setBackgroundColor:[UIColor redColor]];
[fooTroller setView:fooView];
popOver =[[UIPopoverController alloc] initWithContentViewController:fooTroller];
[popOver presentPopoverFromRect:btn.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionLeft
animated:YES];
Any thoughts? It's not respecting the view size.
You should not be calling setView: on the view controller. Let the view controller setup its own view.
The proper way to size a popover is to either override the contentSizeForViewInPopover method of your view controller to return the size or to set the popoverContentSize property on the popover.
UIButton* btn =sender;
UIViewController* fooTroller = [[UIViewController alloc] init];
popOver = [[UIPopoverController alloc] initWithContentViewController:fooTroller];
popOver.popoverContentSize = CGSizeMake(100, 100);
[popOver presentPopoverFromRect:btn.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionLeft
animated:YES];
I created a UpcomingCell.h and .m for the cell. In the button's tap method i tried this
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Storyboard" bundle:nil];
// cameraSystemMenu = [mainStoryboard instantiateViewControllerWithIdentifier:#"CameraSystemMenuViewController"];
UIView *anchor = sender;
UIViewController *viewControllerForPopover =
[storyboard instantiateViewControllerWithIdentifier:#"yourIdentifier"];
self.popover = [[UIPopoverController alloc]
initWithContentViewController:viewControllerForPopover];
[self.popover presentPopoverFromRect:anchor.frame
inView:anchor.superview
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
and I also tried this
self.popoverContent = [[PopOverViewController alloc]init];
UIView *popoverView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 300)];
[popoverView setBackgroundColor:[UIColor purpleColor]];
self.popoverContent.view = popoverView;
self.popoverContent.contentSizeForViewInPopover = CGSizeMake(200, 300);
UIPopoverController *contactPopover =[[UIPopoverController alloc] initWithContentViewController:self.popoverContent];
[contactPopover presentPopoverFromRect:self.remindButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES ];
[contactPopover setDelegate:self];
and countless other popover examples on stackoverflow and I cant get it to work.
Both examples crashes. The first one crashes on
the rect passed in to this method must have non-zero width and height. This will be an exception in a future release
The second one crashes because an UIPopoverController needs to be a property or an instance variable, otherwise it will be deallocated on the end of the method, because the View that's showing it will not retain it
I have a button I have created programmatically within a view controller. Once the button is pressed I want it to to use a method to create the popover programmatically.
The button which is created in the ViewDidLoad in my view controller.m
UIView *moreFundInfoView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 540, 620)];
[self.view addSubview:moreFundInfoView];
[moreFundInfoView setBackgroundColor:[UIColor RMBColor:#"b"]];
btnContact = [UIButton buttonWithType:(UIButtonTypeRoundedRect)];
[btnContact setFrame:CGRectMake(390, 575, contactButton.width, contactButton.height)];
btnContact.hidden = NO;
[btnContact setTitle:#"Contact" forState:(UIControlStateNormal)];
[moreFundInfoView addSubview:btnContact];
[btnContact addTarget:self action:#selector(showContactDetails:) forControlEvents:UIControlEventTouchUpInside];
Then I have the method I use when the button is pressed.
-(void) showContactDetails: (id) sender
{
UIViewController *popoverContent = [[UIViewController alloc]init];
UIView *popoverView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 300)];
[popoverView setBackgroundColor:[UIColor RMBColor:#"b"]];
popoverContent.view = popoverView;
popoverContent.contentSizeForViewInPopover = CGSizeMake(200, 300);
UIPopoverController *contactPopover =[[UIPopoverController alloc] initWithContentViewController:popoverContent];
[contactPopover presentPopoverFromRect:btnContact.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES ];
[contactPopover setDelegate:self];
}
What am I missing here? Cause it runs fine, but as soon as I click the button the app crashes. I think it is a delegate issue, but I am not sure. Any advice would be appreciated.
I think this code will help you. You are certainly missing delegate methods
ViewController *viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
popover.delegate = self;
popover.popoverContentSize = CGSizeMake(644, 425); //your custom size.
[popover presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections: UIPopoverArrowDirectionLeft | UIPopoverArrowDirectionUp animated:YES];
Just make sure you are not forgetting UIPopover Delegate methods or else application will definitely crash. It is mandatory.
UIViewController *controller = [[UIViewController alloc] init];
[view removeFromSuperview]; //view is a view which is displayed in a popover
controller.view = view;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:controller];
popover.delegate = self;
[popover presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
All I had to do was change the property from "retain" to "strong" in the .h file and it works, stopped the app from crashing.
Yes, changing property for "retain" to "strong" makes you to hold your picker view object.
I think the problem with your code was, UIPopoverController object gets deallocated automatically when method finishes.
making strong property gets you to strongly point an object.
I'm attempting to present a popoverView when a barButton is pressed. Unfortunately, the app crashes with the signal SIGABRT every time I try to call it. The "Empty.xib" does have a view designed in it. (As I'm using a barButton, I was unable to use the frame, if you have a workaround for that, please say so too).
- (IBAction)loadPopover:(id)sender
{
UIView *someView = [[UIView alloc] init];
UIViewController *someVC = [[UIViewController alloc] initWithNibName:#"Empty.xib" bundle:[NSBundle mainBundle]];
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:someVC];
someView.frame = CGRectMake(0, 44, 320, 372);
someView.backgroundColor = [UIColor lightGrayColor];
popoverController.delegate = self;
self.popoverView = popoverController;
[self.popoverView presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
// CGRect popoverRect = [self.view convertRect:[btn frame] fromView:[btn superview]];
CGRect popoverRect = CGRectMake(0, 88, 320, 311);
popoverRect.size.width = MIN(popoverRect.size.width, 100);
[self.popoverView presentPopoverFromRect:popoverRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
Remove .xib part from initWithNibName:#"Empty.xib". Change line to this:
UIViewController *someVC = [[UIViewController alloc] initWithNibName:#"Empty" bundle:nil];
Edit:
From here -
The nib file name should not contain any leading path information.
Few suggestions here.
Check if the view's outlet is connected
Why do you need to allocate a UIView like the following? UIView *someView = [[UIView alloc] init];
Check if the sender is of type of UIBarButtonItem
What is the retain policy for self.popoverView? Check if it is retain or strong (if ARC)
Why do you present the popover two times?
Said this, here a simple snippet.
UIBarButtonItem* barButton = (UIBarButtonItem*)sender;
UIViewController *someVC = [[UIViewController alloc] initWithNibName:#"Empty" bundle:[NSBundle mainBundle]];
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:someVC];
popoverController.delegate = self;
self.popoverView = popoverController;
[self.popoverView setPopoverContentSize:CGSizeMake(300, 200)];
[self.popoverView presentPopoverFromBarButtonItem:barButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
P.S. Make attention to memory if you don't use ARC.
Hope it helps.
