My Custom Activity indicator is not overlapping Navigation controller.
Below is my code
func showActivityIndicator(uiView: UIView) {
container.frame = uiView.frame
container.center = uiView.center
container.backgroundColor = UIColorFromHex(0xffffff, alpha: 0.1)
var loadingView: UIView = UIView()
loadingView.frame = CGRectMake(0, 0, self.view.frame.width, self.view.frame.height)
loadingView.center = uiView.center
loadingView.backgroundColor = UIColorFromHex(0x444444, alpha: 0.5)
loadingView.clipsToBounds = true
loadingView.layer.cornerRadius = 10
var imageData = NSData(contentsOfURL: NSBundle.mainBundle()
.URLForResource("synch-loader", withExtension: "gif")!)
let try = UIImage.animatedImageWithData(imageData!)
var imageView = UIImageView(image: try)
imageView.center = uiView.center
imageView.frame = CGRect(x: uiView.frame.width/4, y: uiView.frame.height/2, width: 500, height: 15)
loadingView.addSubview(imageView)
container.addSubview(loadingView)
uiView.addSubview(container)
actInd.startAnimating()
}
func navigationHandling()
{
if self.navigationController != nil {
self.navigationController?.navigationBar.tintColor = utility.uicolorFromHex(0x70B420)
self.navigationController?.navigationBar.barTintColor = utility.uicolorFromHex(0x70B420)
self.navigationController?.navigationBarHidden = false
self.navigationItem.hidesBackButton = true
}
sortingBtn = UIBarButtonItem(image: sortingImg, style: UIBarButtonItemStyle.Done, target: self, action: Selector("sortingPressed:"))
menuBtn = UIBarButtonItem(image: menuImg, style: UIBarButtonItemStyle.Plain, target: self, action : nil)
sortingBtn.tintColor = UIColor.whiteColor()
menuBtn.tintColor = UIColor.whiteColor()
var buttons : NSArray = [menuBtn,sortingBtn]
self.navigationItem.rightBarButtonItems = buttons as [AnyObject]
self.navigationItem.setRightBarButtonItems([menuBtn,sortingBtn], animated: true)
networkLabel.hidden = true
}
I just want to overlap the view on navigation controller so that it don't looks ugly.
I appreciate help!
let appDelegate = UIApplication.sharedApplication().delegate as? AppDelegate
let window = appDelegate?.window
window.addSubview("yourActivityIndicator")
Here add the activity indicator to the window, or pass the window in as the view.
let appDelegate = UIApplication.sharedApplication().delegate as? AppDelegate
let window = appDelegate?.window
showActivityIndicator(window)
The uiView you're passing as parameter to this method
func showActivityIndicator(uiView: UIView)
is your ViewController's view or your UINavigationController's view?
Because if it's your UIViewController's view your custom loading will take it's size and origin, that is under your NavigationBar

Screenshot of the gap
I need to present a popover view from a UIBarbuttonItem in a UIToolbar. But there exists a gap between the popover view and the toolbar.
private func addToolbar() {
let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 50))
let item1 = UIBarButtonItem(image: UIImage(systemName: "pencil"), style: .plain, target: self, action: #selector(item1Pressed(_:)))
let item2 = UIBarButtonItem(image: UIImage(systemName: "house"), style: .plain, target: self, action: #selector(item2Pressed(_:)))
toolBar.sizeToFit()
toolBar.items = [item1, item2]
textField.inputAccessoryView = toolBar
}
class SearchViewController: UIViewController {
let searchBar = UISearchBar()
weak var viewControllerDelegate: SearchViewControllerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
setupView()
setupSearchbar()
}
private func setupView() {
view.backgroundColor = .white
navigationController?.navigationBar.prefersLargeTitles = true
self.title = "Search"
}
private func setupSearchbar() {
searchBar.sizeToFit()
searchBar.placeholder = "Search test"
searchBar.showsCancelButton = true
searchBar.delegate = self
self.navigationItem.titleView = searchBar
}
}
I tried setting the sourceRect of the presented popover view, but the popover view doesn't move down below a certain point.
#objc private func item1Pressed(_ sender: UIBarButtonItem) {
let vc = SearchViewController()
vc.viewControllerDelegate = self
let navVC = UINavigationController(rootViewController: vc)
navVC.modalPresentationStyle = .popover
navVC.popoverPresentationController?.delegate = self
navVC.popoverPresentationController?.permittedArrowDirections = .any
navVC.preferredContentSize = CGSize(width: 500, height: 200)
navVC.popoverPresentationController?.sourceItem = sender
var location = CGPoint(x: 0, y: 0)
if let barItemView = sender.value(forKey: "view") as? UIView {
let barFrame = barItemView.frame
let rect = barItemView.convert(barFrame, to: view)
location = rect.origin
}
navVC.popoverPresentationController?.sourceRect = CGRect(x: location.x, y: location.y+100, width: 0, height: 0)
present(navVC, animated: true)
}
here is the code that I check if they images are tapped but only the 3 image is apply full screen. As you can see I set the image is tapped to statusImageView to call the function of zoomImage So I want fixed for all images.
func imageTapped() {
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageZoom(tapGestureRecognizer:)))
if detailsImage[0].tag == 0 {
detailsImage[0].isUserInteractionEnabled = true
detailsImage[0].addGestureRecognizer(tapGestureRecognizer)
self.statusImageView = detailsImage[0]
}
let tapGestureRecognizer1 = UITapGestureRecognizer(target: self, action: #selector(imageZoom(tapGestureRecognizer:)))
detailsImage[1].isUserInteractionEnabled = true
detailsImage[1].addGestureRecognizer(tapGestureRecognizer1)
self.statusImageView = detailsImage[1]
let tapGestureRecognizer2 = UITapGestureRecognizer(target: self, action: #selector(imageZoom(tapGestureRecognizer:)))
detailsImage[2].isUserInteractionEnabled = true
detailsImage[2].addGestureRecognizer(tapGestureRecognizer2)
self.statusImageView = detailsImage[2]
}
let blackBackgroundColor = UIView()
let tappedImage = UIImageView()
var statusImageView: UIImageView?
let navigationBarView = UIView()
#objc func imageZoom(tapGestureRecognizer: UITapGestureRecognizer) {
annimationImage(detailsImage: statusImageView!)
}
And then I call the annihilationImage function which is takes the statusImageView as input
func annimationImage(detailsImage: UIImageView) {
if let startingFrame = statusImageView?.superview?.convert(statusImageView!.frame, to: nil) {
statusImageView!.alpha = 0
blackBackgroundColor.frame = self.view.frame
blackBackgroundColor.backgroundColor = UIColor.black
blackBackgroundColor.alpha = 0
view.addSubview(blackBackgroundColor)
navigationBarView.frame = CGRect(x: 0, y: 0, width: 1000, height: 100)
navigationBarView.backgroundColor = UIColor.black
navigationBarView.alpha = 0
if let keyWindow = UIApplication.shared.keyWindow {
keyWindow.addSubview(navigationBarView)
}
let tappedImage = UIImageView()
tappedImage.backgroundColor = .gray
tappedImage.frame = startingFrame
tappedImage.contentMode = .scaleToFill
tappedImage.isUserInteractionEnabled = true
tappedImage.image = statusImageView?.image
tappedImage.clipsToBounds = true
view.addSubview(tappedImage)
UIView.animate(withDuration: 0.75, animations: {
tappedImage.frame = CGRect(x: 0, y: y, width: self.view.frame.size.width, height: 300)
})
}
}
I want to make an if statement that while check which image is tapped
You can use tapGestureRecognizer.view for getting a view that is assigned a tap gesture. And by this, you can also get the view tag (your view is corresponding to the image view in your code)
#objc func imageZoom(tapGestureRecognizer: UITapGestureRecognizer) {
let senderView = tapGestureRecognizer.view // Here you get a view that is associated with the gesture
let tag = senderView?.tag // Here you get a tag that is assigned to all image
// Add your condition here by tag
annimationImage(detailsImage: statusImageView!)
}
I am developing an app that contains a login and when logging in for the first time the views that go after logging do not load well the navigation bar, when opening the app for the second time and already with the credentials previously entered, this time if they load well the navigation bar.
Does anyone know why this happens?
my viewWillAppear is like this
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 38, height: 38))
imageView.contentMode = .scaleAspectFit
let image = UIImage(named: "img_header")
imageView.image = image
navigationItem.titleView = imageView
//let image_home = UIImage(named: "ic_home")
//let homeButton = UIBarButtonItem(image: image_home, style: UIBarButtonItemStyle.done, target: self, action: #selector(self.cancelMetod2))
// navigationItem.leftBarButtonItem = homeButton
let color_primary: UIColor = val_colores.hexStringToUIColor(val_colores.colorPrimary)
let color_background_primary: UIColor = val_colores.hexStringToUIColor(val_colores.ColorGrisClaro2)
//icono more
let imagen_more = UIImage (named: "ic_more_menu")!
let buttonMore: UIBarButtonItem = UIBarButtonItem(image: imagen_more, style: UIBarButtonItemStyle.done,target: self, action: #selector(self.moreMetod))
self.navigationItem.rightBarButtonItem = buttonMore
//background color
self.navigationController?.navigationBar.barTintColor = color_primary
//back button color
UIBarButtonItem.appearance().tintColor = color_background_primary
//Since iOS 7.0 UITextAttributeTextColor was replaced by NSForegroundColorAttributeName
//title color
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor: color_background_primary]
//color in carrier, hour, battery
UINavigationBar.appearance().barStyle = UIBarStyle.black
self.navigationController!.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: color_background_primary]
self.navigationController!.navigationBar.barStyle = UIBarStyle.black
self.navigationController!.navigationBar.tintColor = color_background_primary
}
How to create a popover of dynamic size on clicking UitableView cell in swift?
Should i use any tooltip frameworks? or just use apples PopOverViewController functionality?
It works fine in iPad with the below code. but in iphone it appears as a full screen view
Below code works fine and is the solution i got UIPopoverPresentationController on iPhone doesn't produce popover
by #tsik
class CommonViewController: UIViewController, UIPopoverPresentationControllerDelegate{
func adaptivePresentationStyle(
for controller: UIPresentationController,
traitCollection: UITraitCollection)
-> UIModalPresentationStyle {
return .none
}
func showPopover(){
let storyboard = UIStoryboard(name: "Pickers", bundle: nil)
let myViewController = UIViewController()
myViewController.preferredContentSize = CGSize(width: 320, height: 200)
myViewController.modalPresentationStyle = .popover
let popOver = myViewController.popoverPresentationController
popOver?.delegate = self
self.present(myViewController, animated: true, completion: nil)
popOver?.permittedArrowDirections = .init(rawValue: 0)
popOver?.sourceView = self.view
let rect = CGRect(
origin: CGPoint(x: self.view.frame.width/2, y: self.view.frame.height/2),
size: CGSize(width: 1, height: 1)
)
popOver?.sourceRect = rect
}
could you please check this code this is working fine in iphones in my case.
let popoverContent = self.storyboard!.instantiateViewController(withIdentifier: "PopOverViewController")
let ktagForLabel = 100
let popOverWidth = UIScreen.main.bounds.width - 40
if let label = popoverContent.view.viewWithTag(ktagForLabel) as? UILabel {
let descriptionText = self.subcategoryDetailViewModel.displayServiceDescriptionForPopOver(forIndex: sender.tag/10)
label.text = descriptionText
var estimatedTextHeight = descriptionText.heightWithConstrainedWidth(width: popOverWidth, font: UIFont.systemFont(ofSize: 15)) + 16
let nav = UINavigationController(rootViewController: popoverContent)
nav.isNavigationBarHidden = true
nav.modalPresentationStyle = UIModalPresentationStyle.popover
let popover = nav.popoverPresentationController!
estimatedTextHeight = estimatedTextHeight > 150 ? 150: estimatedTextHeight
popoverContent.preferredContentSize = CGSize(width: popOverWidth, height: estimatedTextHeight)
popover.delegate = self
popover.permittedArrowDirections = .up
popover.sourceView = sender
popover.sourceRect = sender.bounds
self.present(nav, animated: true, completion: nil)
}
I have no idea why my code isn't working :
let profileImageView: UIImageView = {
let image = UIImageView()
image.image = UIImage(named: "gameofthrones_splash")
image.translatesAutoresizingMaskIntoConstraints = false
image.contentMode = .scaleAspectFill
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView))
image.addGestureRecognizer(tapGesture)
image.isUserInteractionEnabled = true
return image
}()
This imageView is loaded in the ViewDidLoad (I can see it)
func handleSelectProfileImageView() {
print("123")
}
But nothing get returned in the console when I'm tapping on it ! WTF?
It's in the target. This works when place in the viewDidLoad():
profileImageView.frame = CGRect(x: 60, y: 60, width: 70, height: 70)
view.addSubview(profileImageView)
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView))
profileImageView.addGestureRecognizer(tapGesture)
The target is "self", which is the UIViewController (not the UIImageView). In most cases (I'm sure there are outliers) you want to record a gesture in a view, but work with the gesture in a view controller.
Okay the solution was quite simple actually. You have to make it a lazy var instead of a let.
lazy var profileImageView: UIImageView = {
let image = UIImageView()
image.image = UIImage(named: "gameofthrones_splash")
image.translatesAutoresizingMaskIntoConstraints = false
image.contentMode = .scaleAspectFill
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView))
image.addGestureRecognizer(tapGesture)
image.isUserInteractionEnabled = true
return image
}()
Swift 3.0:
There was some error I removed it -
Put this code in viewdidLoad
override func viewDidLoad() {
super.viewDidLoad()
var profileImageView:UIImageView {
var image = UIImageView()
image.backgroundColor = UIColor.red;
image.frame = CGRect(x: 0, y: 0, width: 44, height: 44)
image.translatesAutoresizingMaskIntoConstraints = false
image.contentMode = .scaleAspectFill
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView))
image.addGestureRecognizer(tapGesture)
image.isUserInteractionEnabled = true
return image
}
view.addSubview(profileImageView);
// Do any additional setup after loading the view.
}
func handleSelectProfileImageView() {
print("123")
}
Just to test I removed the image, you can add it. But it's working fine.
I fixed this issue using an UIButton ->
let profileImageView: UIButton = {
let iv = UIButton()
let image = UIImage(named: "r2d2")
iv.setImage(image, for: .normal)
iv.translatesAutoresizingMaskIntoConstraints = false
iv.addTarget(self, action: #selector(selectProfileImage), for: .touchUpInside)
iv.isUserInteractionEnabled = true
return iv
}()
#objc func selectProfileImage(){
print("Hello")
}
