How to Fix the "Uipopovercontroller Is Deprecated" Warning

How can I fix the UIPopoverController is deprecated warning?

You no longer need UIPopoverController for presenting a view controller.
Instead you can set the modalPresentationStyle of view controller to UIModalPresentationPopover.

You can use the following code for that:

avc.modalPresentationStyle = UIModalPresentationPopover;
avc.popoverPresentationController.sourceView = theButton;
[self presentViewController:avc animated:YES completion:nil];

UIModalPresentationPopover

In a horizontally regular environment, a
presentation style where the content is displayed in a popover view.
The background content is dimmed and taps outside the popover cause
the popover to be dismissed. If you do not want taps to dismiss the
popover, you can assign one or more views to the passthroughViews
property of the associated UIPopoverPresentationController object,
which you can get from the popoverPresentationController property.

In a horizontally compact environment, this option behaves the same as
UIModalPresentationFullScreen.

Available in iOS 8.0 and later.

You need to set either sourceView or barButtonItem property, else it will crash with the following message:

*** Terminating app due to uncaught exception 'NSGenericException', reason: 'UIPopoverPresentationController (***) should have a non-nil
sourceView or barButtonItem set before the presentation occurs.'

For anchoring the popover arrow correctly, you need to specify the sourceRect property also.

avc.modalPresentationStyle                   = UIModalPresentationPopover;
avc.popoverPresentationController.sourceView = self.view;
avc.popoverPresentationController.sourceRect = theButton.frame;
[self presentViewController:avc animated:YES completion:nil];

Refer sourceView and sourceRect for more details.

UIPopoverController deprecated

UIModalPresentationPopover

UIModalPresentationPopover is replacement of UIPopoverController.

Available in iOS 8.0 and later.

ModalViewController *modal = [[ModalViewController alloc] init];
modal.modalPresentationStyle = UIModalPresentationPopover;
modal.transitioningDelegate = self;
modal.popoverPresentationController.sourceView = self.view;
modal.popoverPresentationController.sourceRect = CGRectZero;
modal.popoverPresentationController.delegate = self;

[self presentViewController:modal animated:YES completion:nil];

iOS 7 - UIPopoverController : deprecated arrows?

This looks like a bug in the documentation. Arrows were probably on the chopping block by designers but the decision was reverted in usability testing.

If you look in UIPopoverController.h, you don't see any deprecation attributes (e.g. NS_AVAILABLE_IOS or NS_DEPRECATED_IOS):

/* Returns the direction the arrow is pointing on a presented popover. Before 
   presentation, this returns UIPopoverArrowDirectionUnknown.
 */
@property (nonatomic, readonly) UIPopoverArrowDirection popoverArrowDirection;

Contrast this with -[NSString sizeWithFont:constrainedToSize:]:

- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size NS_DEPRECATED_IOS(2_0, 7_0, "Use -boundingRectWithSize:options:attributes:context:");

These attributes are important because they generated the compiler warnings and errors. They are also maintained by the people who actually code the UI.

Combining the lack of attributes with the fact that the behavior you see directly contradicts the documentation, you really shouldn't worry about it. If it really bothers you, can file a bug report.

UIPopoverController trouble

Your code is quite strange.

For example why do you create a view and do you add it to the content view of your popover?

Then, you have to make attention to memory leaks. There a lot of them in your code.

That said, here a simple example for display a UIViewcontroller within a UIPopoverController.

- (IBAction)yourAction:(id)sender

    UIButton* senderButton = (UIButton*)sender;

    UIViewController* yourController = [[UIViewController alloc] init];

    UIPopoverController* pop = [[UIPopoverController alloc] initWithContentViewController:yourController];
    pop.delegate = self;
    pop.popoverContentSize = CGSizeMake(300, 300);    

    self.popover = pop;

    [pop presentPopoverFromRect:senderButton.bounds inView:senderButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    pop.passthroughViews = nil;

    [yourController release];
    [pop release];
}

where self.popover is a @property with a retain policy. In this manner in UIPopoverControllerDelegate methods (or wherever you want), you can release your popover and/or dismiss it.

Hope it helps.

P.S. Check the code because I've written by hand.

Edit

Usually when you create a popover, its content view controller is or a custom UIViewController or a UINavigationController (in this case you want to take advantage of its navigation bar).

For example, instead of the simple UIViewController, you could create a custom one

//.h
@interface CustomUIViewController : UIViewController

@end

//.m
@implementation CustomUIViewController 

// other code here...

- (void)viewDidLoad
{
   // here you are sure that the view has been loaded in memory (alternatively override loadView method), so
   UIView* greenView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
   green.backgroundColor = [UIColor greenColor];
   [self.view addSubview:greenView];
   [greenView release];
}

@end

and use it within a a popover

- (IBAction)yourAction:(id)sender

    UIButton* senderButton = (UIButton*)sender;

    CustomUIViewController* yourController = [[CustomUIViewController alloc] init];

    // same as before...
}

iOS Popover Is Displaying On TextView

I am not sure why this was occurring but the quick solution is to move the frame where you want it. I did this with the code below:

let absoluteframe = patientTextField!.convertRect(patientTextField!.frame, fromView: self.scrollView)
popoverViewController.popoverPresentationController!.sourceRect = CGRectMake(absoluteframe.minX + 60,absoluteframe.minY + 20,0,0)

First, you need to get the frame for the item the popup is anchored to. Then you can set the sourceRect by updating the rectangle position with their current x and y values. Hope this helps anyone with similar problems!
