I am trying to create number pad in iPad using popover view controller. Everything is achieved but there is a shadow beneath the pop view. I tried to remove that shadow but nothing worked for me. Here is my code which presents pop over view in my view controller.
let vc = self.storyboard?.instantiateViewController(withIdentifier: "PopOverVC") as? PopOverVC
vc?.modalPresentationStyle = .popover
vc?.preferredContentSize = CGSize(width: 280, height: 425)
vc?.delegate = self
if let popoverPresentationController = vc?.popoverPresentationController {
popoverPresentationController.permittedArrowDirections = [.down, .up, .right, .left]
popoverPresentationController.sourceView = self.view
popoverPresentationController.sourceRect = txtNumber.frame
popoverPresentationController.delegate = self
if let popoverController = vc {
present(popoverController, animated: false, completion: nil)
}
}
Can anybody help me removing the shadow? Thanks in advance!!

I am NOT USING StoryBoard in my project. I have presented one view controller as popOver Style.
let vcOne = ViewControllerOne()
vcOne.showCorrectionFactor = true
vcOne.modalPresentationStyle = .popover
let pop = vcOne.popoverPresentationController
pop?.sourceView = self.view
pop?.sourceRect = sender.frame
vcOne.preferredContentSize = CGSize(width: 400, height: 500)
self.present(vcOne, animated: true, completion: nil)
Now i want to navigate to other view controller from ViewControllerOne() and with in this pop up.
I am doing it like
let vc = PairViewController()
self.navigationController?.pushViewController(vc, animated: true)
But self.navigationController? is getting nil value. How can i achieve this without story board.
You did not embed ViewControllerOne in a UINavigationController, so of course self.navigationController is nil.
Just do this:
// embed it!
let navController = UINavigationController(rootViewController: vcOne)
// get the popover presentation controller from the navigation controller!
let pop = navController.popoverPresentationController
pop?.sourceView = self.view
pop?.sourceRect = sender.frame
vcOne.preferredContentSize = CGSize(width: 400, height: 500)
// present navController rather than vcOne!
self.present(navController, animated: true, completion: nil)
I have an options button (that 3 vertical dotted button) on top of the view controller.
When I click that button, A list view should appear like in many other apps like WhatsApp...
I really don't know how to position it always near to the button programmatically.
Placing at the left-bottom of an existing view is quite easier:
func placeSubView(existingView: UIView)
{
let desiredWidth = CGFloat(50.0)
let desiredHeight = CGFloat(35.0)
let (x, y) = (existingView.frame.origin.x - desiredWidth, existingView.frame.origin.y + existingView.frame.size.height)
let desiredView = UIView(frame: CGRect(x: x, y: y, width: desiredWidth, height: desiredHeight))
existingView.superview?.addSubview(desiredView)
}
UPDATE:
In case you are looking for popupo menu like view, you should search about UIPopoverPresentationController.
Something like this.
Use this method and make PopoverViewController a table view controller if you want a list.
#IBAction func displayPopover(_ sender: UIBarButtonItem) {
let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "PopoverViewController")
vc.modalPresentationStyle = .popover
let popover: UIPopoverPresentationController = vc.popoverPresentationController!
popover.barButtonItem = sender
present(vc, animated: true, completion:nil)
}
I created simple popup in tableview however I do not know how to make the subview transparent, right now it is full black.
This is how I created the popup inside tableview cell button click:
let vc = self.storyboard?.instantiateViewController(withIdentifier: "RatingViewController") as! RatingViewController
vc.modalPresentationStyle = .popover
vc.preferredContentSize = CGSize(200, 100)
if let presentationController = vc.popoverPresentationController {
presentationController.delegate = self
presentationController.permittedArrowDirections = .up
presentationController.sourceView = self.view
presentationController.sourceRect = CGRect(0, 0, 50, 50)
self.present(vc, animated: true, completion: nil)
}
What should I do to make it transparent? My subview for the RatingViewController is white but for some reason it shows as black.
I have a view controller that I want to present as a popover. How can I change its size?
let carsViewController = CarsViewController()
carsViewController.modalPresentationStyle = .Popover
if let popoverPresentationController = a carsViewController.popoverPresentationController {
popoverPresentationController.permittedArrowDirections = .Up
popoverPresentationController.sourceView = carsButton
presentViewController(alertsViewController, animated: true, completion: nil)
}
It took me some time but I finally found an answer to this. It is as simple as adding the following line after initialising the view controller.
carsViewController.preferredContentSize = CGSize(width: 220,height:90)
I'm presenting a Navigation Controller as a popover. First time a do it I can push to another View Controller with any issue. But, second time a present another controller the same way I can't perform a push because the self.navigationController of the presented Controller is nil. This is the piece of code I'm using to present the Controller
func instantiateEditController(view : UIView) -> UINavigationController
{
let popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("Edit Controller") as MCMEditController
popoverContent.preferredContentSize = CGSizeMake(320, 480)
let navController = MCMBaseNavigationController(rootViewController: popoverContent)
navController.modalPresentationStyle = UIModalPresentationStyle.Popover
navController.navigationBar.tintColor = UIColor.whiteColor()
let popover = navController.popoverPresentationController
popover?.sourceView = view
popover?.sourceRect = CGRectMake(0, 0, view.frame.size.width, view.frame.size.height)
return navController
}
Note: The Navigation Controller is always presented, but just the first time I perform pushes. And this code is for be used in iPad.
Because of the nature of Storyboards and not being able to show that here, I'm not sure where your issue is exactly.
However I successfully setup a project that works using segues. I changed your code to the following:
func instantiateEditController(view : UIView) -> UINavigationController
{
if let popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("Edit Controller") as? MCMEditController {
popoverContent.preferredContentSize = CGSizeMake(320, 480)
let navController = UINavigationController(rootViewController: popoverContent)
navController.modalPresentationStyle = UIModalPresentationStyle.Popover
navController.navigationBar.tintColor = UIColor.whiteColor()
let popover = navController.popoverPresentationController
popover?.sourceView = view
popover?.sourceRect = CGRectMake(0, 0, view.frame.size.width, view.frame.size.height)
return navController
} else {
return UINavigationController(rootViewController: self) // not recommend to keep this, I'm on Swift 1.2 and this was an easy fix to resolve the errors
}
}
To present this popover I set up this IBAction in my ViewController (sender in my case was a UIButton)
#IBAction func presentPopover(sender: AnyObject) {
if let view = sender as? UIView {
let controller = instantiateEditController(view)
let popover = UIPopoverController(contentViewController: controller)
popover.presentPopoverFromRect(view.frame, inView: self.view, permittedArrowDirections:UIPopoverArrowDirection.Any, animated: true)
}
}
The last thing that could be the issue is make sure your segues are using the segue type "show" for all the segues to make sure the transition between them use the navigation controller push:
Hope this helps!
