I want to present a ViewController as popover in Swift 4, but it presents the Viewcontroller normally, this is the code:
class CustomTabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
let favViewController = TrialViewController()
let exhibtionViewController = TrialViewController()
let menuViewController = ttttViewController()
let notificationViewController = TrialViewController()
let profileViewController = ttttViewController()
favViewController.tabBarItem.title = "first"
exhibtionViewController.tabBarItem.title = "second"
menuViewController.tabBarItem.title = "third"
notificationViewController.tabBarItem.title = "forth"
profileViewController.tabBarItem.title = "fifth"
favViewController.tabBarItem.image = UIImage(named:"home25")
exhibtionViewController.tabBarItem.image = UIImage(named: "bag25")
menuViewController.tabBarItem.image = UIImage(named: "main_add_25")
notificationViewController.tabBarItem.image = UIImage(named: "notification25")
profileViewController.tabBarItem.image = UIImage(named: "man_man25")
let tabBarItemWidth = Int(self.tabBar.frame.size.width) / (self.tabBar.items?.count)!
let x = tabBarItemWidth * 3;
let newRect = CGRect(x: x, y: 0, width: tabBarItemWidth, height: Int(self.tabBar.frame.size.height))
print(newRect)
menuViewController.modalPresentationStyle = .popover
menuViewController.view.frame = newRect
menuViewController.preferredContentSize = CGSize(width: 150,height: 150)
if let popoverMenuViewController = menuViewController.popoverPresentationController {
popoverMenuViewController.permittedArrowDirections = .down
popoverMenuViewController.delegate = menuViewController as? UIPopoverPresentationControllerDelegate
popoverMenuViewController.sourceRect = newRect
popoverMenuViewController.sourceView = self.tabBar
present(menuViewController, animated: true, completion: nil)
}
viewControllers = [favViewController, exhibtionViewController, menuViewController, notificationViewController, profileViewController]
}
}
what is the problem with my code?
override func viewDidAppear(_ animated: Bool) {
let vc = self.storyboard?.instantiateViewController(withIdentifier: "bbb") as! ttttViewController
vc.modalPresentationStyle = .popover //presentation style
vc.preferredContentSize = CGSize(width: 150,height: 150)
vc.popoverPresentationController?.delegate = self as! UIPopoverPresentationControllerDelegate
vc.popoverPresentationController?.sourceView = view
vc.popoverPresentationController?.sourceRect = self.tabBar.frame
self.present(vc, animated: true, completion: nil)
}
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
}

when i try changing image nothing happen
tabBarItems[index].image = UIImage(named: "Home_Tab")

Same for selected image
it works when i set image in createTabBarItemSelectionOverlay method
i tried removing image and setting it again but no success
also tried to set image with .alwaysOriginal render mode no luck
please help where am i doing wrong ??
Thank you...little help will be appriciated
I am trying to present popover viewcontroller with down arrow over my Tabbarview controller, but it is stopped appearing if i choose down, and in case of up it is displaying.
So my questions are
1)How to make arrow down if UIPopoverArrowDirection.down is not working ? And why is it not working ?
2) How to debug and find the error that why it is not displaying, there are no logs been printed for this.
3)How to display Arrow in centre of the view not in the side.
my code is,
let popController = UIStoryboard(name: kStoryboard.login, bundle: nil).instantiateViewController(withIdentifier: "popoverId")
popController.modalPresentationStyle = UIModalPresentationStyle.popover
popController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.down
popController.popoverPresentationController?.backgroundColor = UIColor.Text.orange
popController.popoverPresentationController?.delegate = self
popController.popoverPresentationController?.sourceView = self.view
popController.popoverPresentationController?.sourceRect = CGRect(x: 0, y: 0, width: 100, height: 100)
// present the popover
self.present(popController, animated: true, completion: nil)
func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle
{
return UIModalPresentationStyle.none
}
I have given preferredcontentsize from storyboard.
The problem is that currently you are not providing a sourceView + preferredContentSize
import UIKit
class ViewController: UIViewController , UIPopoverPresentationControllerDelegate{
#IBOutlet weak var aa: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(_ animated: Bool)
{
let popController = UIStoryboard(name:"Main", bundle: nil).instantiateViewController(withIdentifier: "popoverId")
popController.modalPresentationStyle = UIModalPresentationStyle.popover
popController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.down
popController.popoverPresentationController?.backgroundColor = UIColor.red
popController.popoverPresentationController?.delegate = self
popController.popoverPresentationController?.sourceView = self.aa
popController.popoverPresentationController?.sourceRect = CGRect(x: 20, y: 20, width: 100, height: 100)
popController.preferredContentSize = CGSize.init(width: 200, height: 200)
// present the popover
self.present(popController, animated: true, completion: nil)
}
func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle
{
return UIModalPresentationStyle.none
}
}
After I updated my iPhone to iOS 10 I noticed this very strange constraint issue with a UITextField in a UINavigationBar has appeared in my app iOS Tipped. I thought updating my Xcode project to swift 3 would fix it but the problem persists. For some reason this ins't an issue with iOS 9 and lower.
Please download my app Tipped... it's free and you will be able to see
the issue described below.
1: When I launch my app and tap the tab bar to the viewController with the textfield constraint issue in the navigation bar I get this
2: When I press another tab bar option (like the home page) the tap the search tab bar option (navigating back to the page with the issue) I get this
3: Also when I tap one of the segment buttons on the search page with the constraint issue. The constraint issue will reappear and the textfield will go too far to the right.
I have tried the below code to try to fix the problem but nothing seems to be working. Really stuck here any help would be like awesome.
override func viewWillAppear(_ animated: Bool) {
// searchTextField.becomeFirstResponder()
print("viewWillAppear: searchPageViewController")
navigationView.setNeedsLayout()
navigationView.updateConstraintsIfNeeded()
searchTextField.updateConstraints()
searchTextField.setNeedsLayout()
}
Below is the code from the viewcontroller that I am having trouble with.
class SearchPageViewController: UIPageViewController, UISearchBarDelegate, UISearchDisplayDelegate, UIPageViewControllerDataSource, UIPageViewControllerDelegate, UIScrollViewDelegate, UITextFieldDelegate {
//%%% customizeable button attributes
let X_BUFFER:CGFloat = 0.0; //%%% the number of pixels on either side of the segment
let Y_BUFFER:CGFloat = 0.0; //%%% number of pixels on top of the segment
let HEIGHT:CGFloat = 44.0; //%%% height of the segment
//%%% customizeable selector bar attributes (the black bar under the buttons)
let BOUNCE_BUFFER:CGFloat = 10.0; //%%% adds bounce to the selection bar when you scroll
let ANIMATION_SPEED:CGFloat = 0.2; //%%% the number of seconds it takes to complete the animation
let SELECTOR_Y_BUFFER:CGFloat = 40.0; //%%% the y-value of the bar that shows what page you are on (0 is the top)
let SELECTOR_HEIGHT:CGFloat = 4.0; //%%% thickness of the selector bar
let X_OFFSET:CGFloat = 0.0; //%%% for some reason there's a little bit of a glitchy offset. I'm going to look for a better workaround in the future

I figured it out. Inside the widen textfield function. I needed to change the following line:
searchBarView.frame = CGRect(x: 16, y: 5, width: self.view.frame.width, height: 34)
to
searchBarView.frame = CGRect(x: 8, y: 5, width: self.view.frame.width - 16, height: 34)
I want to show UITableViewController as popup on button press. I am able to show popup using this code
let menuViewController = popTableViewController() //popTableViewController
menuViewController.modalPresentationStyle = .Popover
menuViewController.preferredContentSize = CGSizeMake(320, 132)
//menuViewController.tableView = FrontTable
let popoverMenuViewController = menuViewController.popoverPresentationController
popoverMenuViewController?.permittedArrowDirections = .Any
popoverMenuViewController?.delegate = self
popoverMenuViewController?.sourceView = sender
popoverMenuViewController?.sourceRect = CGRect(
x: 10,
y: 10,
width: 1,
height: 1)
presentViewController(
menuViewController,
animated: true,
completion: nil)
but it is showing blank table view in popup. I have also added the content in tableview class but it not showing any reflection on result.
Try adding below code in your UIViewController
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return .None
}
or you can try below code to create popover
let mpopover = self.storyboard?.instantiateViewControllerWithIdentifier("breedPop") as! breedPopover
mpopover.delegate = self
self.citiesPopover = mpopover
citiesPopover!.modalPresentationStyle = .Popover
citiesPopover!.preferredContentSize = CGSizeMake(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height/2)
let popoverPresentationViewController = citiesPopover!.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = UIPopoverArrowDirection.Any
popoverPresentationViewController?.delegate = self
popoverPresentationViewController?.sourceView = breedTextField
popoverPresentationViewController?.sourceRect = CGRectMake(breedTextField.frame.width, breedTextField.frame.height*3, 0, 0)
presentViewController(citiesPopover!, animated: true, completion: nil)
The Code I Have written for loading view controllers in Page View Controllers.
Programatically creating four view controllers and adding them to Page View Controller.
I have changed the view controllers frame position but still not changing in the app
let controller: UIViewController = UIViewController()
print(controller.view.frame)
controller.view.frame = CGRectMake(10, 20, self.view.frame.width/2, self.view.frame.height - 20)
print(controller.view.frame)
controller.view.backgroundColor = UIColor.blackColor()
let controller2: UIViewController = UIViewController()
controller2.view.backgroundColor = UIColor.redColor()
let controller3: UIViewController = UIViewController()
controller3.view.backgroundColor = UIColor.blackColor()
let controller4: UIViewController = UIViewController()
controller4.view.backgroundColor = UIColor.greenColor()
let p1 = controller
let p2 = controller2
let p3 = controller3
let p4 = controller4
myViewControllers = [p1,p2,p3,p4]
for index in 0 ..< myViewControllers.count {
NSLog("\(myViewControllers[index])")
}
let startingViewController = self.viewControllerAtIndex(0)
let viewControllers: NSArray = [startingViewController]
self.setViewControllers(viewControllers as? [UIViewController], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: {(done: Bool) in
})
