    I ended up creating my custom tooltip/popover class.

    Can be initalised with any content view and dynamically adjusts it's frame.

    Hope it helps.

    Edit: As stated by Soberman, since iOS 8 it is possible to present popovers on iPhone using public APIs, so this answer is probably not relevant anymore.


    As stated in Apple's documentation on UIPopoverController:

    Popover controllers are for use exclusively on iPad devices.

    So there is no way to use this class in iPhone application unfortunately. But there are a couple of custom third-party implementations of the functionality provided by UIPopoverController which add iPhone support and more. See https://github.com/50pixels/FPPopover for example.

    Edit: There also is another highly customizable popover implementation for both iPhone/iPad worth checking out: https://github.com/nicolaschengdev/WYPopoverController.

    You CAN use popoverController in iPhone apps.

    1. Create a category

    // UIPopoverController+iPhone.h file
    @interface UIPopoverController (iPhone)
    + (BOOL)_popoversDisabled;
    @end
    
    // UIPopoverController+iPhone.m file
    @implementation UIPopoverController (iPhone)
    + (BOOL)_popoversDisabled {
        return NO; 
    } 
    @end
    

    2. Import it to your class and use popover in iPhone as usual.

    But remember that this is private method and Apple can reject your app. But I know people who use this normally and Apple published their apps.

    Since iOS8 we are now able to create popovers, that will be the same on iPhone, as on iPad, which would be especially awesome for those who make universal apps, thus no need to make separate views or code.

    You can get the class as well as demo project here: https://github.com/soberman/ARSPopover

    All you need to do is subclass UIViewController, conform to the UIPopoverPresentationControllerDelegate protocol and set desired modalPresentationStyle along with the delegate value:

    // This is your CustomPopoverController.m
    
    @interface CustomPopoverController () <UIPopoverPresentationControllerDelegate>
    
    @end
    
    @implementation CustomPopoverController.m
    
    - (instancetype)init {
        if (self = [super init]) {
            self.modalPresentationStyle = UIModalPresentationPopover;
            self.popoverPresentationController.delegate = self;
        }
        return self;
    }
    
    - (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {
        return UIModalPresentationNone; //You have to specify this particular value in order to make it work on iPhone.
    }
    

    Afterwards, instantiate your newly created subclass in the method from which you want to show it and assign two more values to sourceView and sourceRect. It looks like this:

    CustomPopoverController *popoverController = [[CustomPopoverController alloc] init];
    popoverController.popoverPresentationController.sourceView = sourceView; //The view containing the anchor rectangle for the popover.
    popoverController.popoverPresentationController.sourceRect = CGRectMake(384, 40, 0, 0); //The rectangle in the specified view in which to anchor the popover.
    [self presentViewController:popoverController animated:YES completion:nil];
    

    And there you have it, nice, neat blurred popover.

    If you want to do it in Swift, I believe the code is the following:

    extension UIPopoverController {
        class var _popoversDisabled : Bool {
        get { return false }
        }
    }
    

    Edit: It is working in Xcode 6 beta 4 on iPhone with iOs7.1

    So @Sobermans answer didn't really solve the issue from start to finish for me so I want to detail how I got it done using the docs. That being said I do like the idea of using your own presentation controller subclass to manage all of the customisation you want to exhibit.

    1. Create your controller to present

    The first step is instantiating the controller you want to present:

    let vc: UIViewController = ...
    vc.modalPresentationStyle = .Popover
    vc.preferredContentSize = CGSize(width: CGRectGetWidth(view.bounds)/2, height: 100)
    

    Now we have a controller with the popover presentation style and an arbitrary content size.

    2. Implement adaptivePresentationStyleForPresentationController

    By default UIPopoverPresentationController will present on full screen on iPhone so to prevent this behaviour you need to force the adaptive presentation style to none.

    First we set the delegate of the popover presentation controller

    vc.popoverPresentationController.delegate = self;
    

    Then we implement UIPopoverPresentationControllerDelegate

    func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
        return .None;
    }
    

    3. Present and configure popup

    First we need to call presentViewController and only after that can we configure the popover:

    presentViewController(vc, animated:true, completion:nil)
    if let popover = vc.popoverPresentationController {
        popover.permittedArrowDirections = .Right | .Left
        popover.sourceView = button
        popover.sourceRect = button.bounds
    }
