How to present popover properly in iOS 8

ios, ios8, swift, uipopover, uipopovercontroller

Solution

Okay, A housemate took a look at it and figured it out:

 func addCategory() {

    var popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController
    var nav = UINavigationController(rootViewController: popoverContent)
    nav.modalPresentationStyle = UIModalPresentationStyle.Popover
    var popover = nav.popoverPresentationController
    popoverContent.preferredContentSize = CGSizeMake(500,600)
    popover.delegate = self
    popover.sourceView = self.view
    popover.sourceRect = CGRectMake(100,100,0,0)

    self.presentViewController(nav, animated: true, completion: nil)

}

That's the way.

You don't talk to the popover itself anymore, you talk to the view controller inside of it to set the content size, by calling the property `preferredContentSize`

Problem

I'm trying to add a UIPopoverView to my Swift iOS 8 app, but I am unable to access the PopoverContentSize property, as the popover does not show in the correct shape. my code: ``` var popover: UIPopoverController? = nil func addCategory() { var newCategory = storyboard.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController var nav = UINavigationController(rootViewController: newCategory) popover = UIPopoverController(contentViewController: nav) popover!.setPopoverContentSize(CGSizeMake(550, 600), animated: true) popover!.delegate = self popover!.presentPopoverFromBarButtonItem(self.navigationItem.rightBarButtonItem, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true) } ``` output: When I am doing the same thing through UIPopoverPresentationController, I still don't get it done. this is my code: ``` func addCategory() { var popoverContent = self.storyboard.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController var nav = UINavigationController(rootViewController: popoverContent) nav.modalPresentationStyle = UIModalPresentationStyle.Popover var popover = nav.popoverPresentationController as UIPopoverPresentationController popover.delegate = self popover.popoverContentSize = CGSizeMake(1000, 300) popover.sourceView = self.view popover.sourceRect = CGRectMake(100,100,0,0) self.presentViewController(nav, animated: true, completion: nil) } ``` I get the exact same output. How do I customize the size of my popover? Any help would be highly appreciated!
