Custom titleView changes location after push and pop new screen in stack - ios

I'm trying to implement custom titleView for navigation controller with "title" and "description" labels. If I placed this titleView on first VC, it looks good. If I push second VC into navigation stack and pop it, location of the titleView is changed.
titleView's constraints:
titleLabel.translatesAutoresizingMaskIntoConstraints = false
descriptionLabel.translatesAutoresizingMaskIntoConstraints = false
titleLabel.widthAnchor.constraint(equalTo: widthAnchor).isActive = true
descriptionLabel.widthAnchor.constraint(equalTo: titleLabel.widthAnchor).isActive = true
titleLabel.topAnchor.constraint(equalTo: topAnchor).isActive = true
descriptionLabel.bottomAnchor.constraint(equalTo: bottomAnchor, constant: 2.0).isActive = true
In viewDidLoad of VC I use follow code to insert titleView:
navigationItem.titleView = BarTitleView()
navigationItem.titleView?.bounds = CGRect(x: 0, y: 0, width: view.bounds.width, height: 44)
navigationItem.titleView?.updateConstraints()
I tried to insert follow lines into viewWillAppear (second VC has different bar buttons and it can be root of problem), but nothing changes
navigationItem.titleView?.bounds = CGRect(x: 0, y: 0, width: view.bounds.width, height: 44)
navigationItem.titleView?.updateConstraints()
How can I fixed this issue?

I have created a Title and Subtitle in the Navigation bar without the need for Interface Builder and constraint modification.
My Function to create the title view looks as follows:
class func setTitle(title:String, subtitle:String) -> UIView {
let titleLabel = UILabel(frame: CGRect(x: 0, y: -8, width: 0, height: 0))
titleLabel.backgroundColor = UIColor.clear
titleLabel.textColor = UIColor.white
titleLabel.font = UIFont.boldSystemFont(ofSize: 17)
titleLabel.text = title
titleLabel.sizeToFit()
let subtitleLabel = UILabel(frame: CGRect(x: 0, y: 12, width: 0, height: 0))
subtitleLabel.backgroundColor = UIColor.clear
subtitleLabel.textColor = UIColor.white
subtitleLabel.font = UIFont.systemFont(ofSize: 12)
subtitleLabel.text = subtitle
subtitleLabel.sizeToFit()
// Fix incorrect width bug
if (subtitleLabel.frame.size.width > titleLabel.frame.size.width) {
var titleFrame = titleLabel.frame
titleFrame.size.width = subtitleLabel.frame.size.width
titleLabel.frame = titleFrame
titleLabel.textAlignment = .center
}
let titleView = UIView(frame: CGRect(x: 0, y: 0, width: titleLabel.frame.size.width, height: titleLabel.frame.size.height))
titleView.addSubview(titleLabel)
titleView.addSubview(subtitleLabel)
let widthDiff = subtitleLabel.frame.size.width - titleLabel.frame.size.width
if widthDiff < 0 {
let newX = widthDiff / 2
subtitleLabel.frame.origin.x = abs(newX)
} else {
let newX = widthDiff / 2
titleLabel.frame.origin.x = newX
}
return titleView
}
Then to use the title view in any view controller I just call this line:
self.navigationItem.titleView = Functions.Views.setTitle(title: "Title String", subtitle: "Subtitle String")

Programatically created UISwitch non-responsive

I have created a table that looks like what you see in the screenshot.
Here is the code:
lazy var contentSize = CGSize(width: self.view.frame.width, height: self.view.frame.height)
lazy var scrollView : UIScrollView = {
let scrollView = UIScrollView(frame: view.bounds)
scrollView.backgroundColor = .white
scrollView.frame = self.view.bounds
scrollView.contentSize = CGSize(width: self.view.frame.width, height: self.view.frame.height * 200)
scrollView.autoresizingMask = UIView.AutoresizingMask.flexibleHeight
scrollView.bounces = true
return scrollView
}()
lazy var containerView : UIView = {
let view = UIView()
view.backgroundColor = .white
view.frame.size = contentSize
return view
}()
let weekStack = UIStackView()
weekStack.axis = .vertical
weekStack.distribution = .fillProportionally
weekStack.spacing = 2
containerView.addSubview(weekStack)
weekStack.translatesAutoresizingMaskIntoConstraints = false
weekStack.topAnchor.constraint(equalTo: restaurantImage.bottomAnchor, constant: 20).isActive = true
weekStack.leadingAnchor.constraint(equalTo: containerView.safeAreaLayoutGuide.leadingAnchor, constant: 20).isActive = true
weekStack.trailingAnchor.constraint(equalTo: containerView.safeAreaLayoutGuide.trailingAnchor, constant: -20).isActive = true
let arrayOfDays = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
for index in 0...arrayOfDays.count - 1 {
let dayStack = UIStackView()
weekStack.addArrangedSubview(dayStack)
dayStack.axis = .horizontal
dayStack.distribution = .fillEqually
dayStack.spacing = 4
let daySwitch = UISwitch(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
dayStack.addArrangedSubview(daySwitch)
let dayLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 20, height: 0))
dayLabel.text = arrayOfDays[index]
dayLabel.textAlignment = .center
dayLabel.font = UIFont(name: "NexaLight", size: 16)
dayStack.addArrangedSubview(dayLabel)
let startTextField = UITextField(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
startTextField.placeholder = "Open"
startTextField.textAlignment = .center
startTextField.delegate = self
startTextField.text = "9"
startTextField.font = UIFont(name: "NexaLight", size: 16)
dayStack.addArrangedSubview(startTextField)
startTextField.inputView = timePicker
startTextField.inputAccessoryView = toolbar
let closeTextField = UITextField(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
closeTextField.placeholder = "Close"
closeTextField.textAlignment = .center
closeTextField.text = "23"
closeTextField.font = UIFont(name: "NexaLight", size: 16)
closeTextField.delegate = self
dayStack.addArrangedSubview(closeTextField)
closeTextField.inputView = timePicker
closeTextField.inputAccessoryView = toolbar
}
The problem is that the last 2 switches are not responding as shown in the screenshot. I cannot turn them on. I also cannot interact with the last 2 rows of text fields where you see "9" and "23". This is from the simulator by the way.

Swift Add UIView with subviews to titleView

I'd like to customize my navigation bar and insert a UIView with two subviews into the title view of the navigation bar.
Unfortunately the subviews aren't displayed.
Do you have any idea why?
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height)
let searchIcon = UIButton()
searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.layer.frame = CGRect(x: 0, y: (UIScreen.main.bounds.size.height - 28) / 2, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: UIScreen.main.bounds.size.height, width: UIScreen.main.bounds.size.width-28, height: UIScreen.main.bounds.size.height)
titleLabel.textColor = UIColor(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(self.titleLabel)
self.navigationItem.titleView = titleContainer
problem and expected solution:
Why did you use height of all the element as UIScreen.main.bounds.size.height? Please try the below code.
P.S. I have changed the color of searchIcon as i didn't have the image and changed the color of text of label and added some text so that it is visible.
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 45)
let searchIcon = UIButton()
//searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.backgroundColor = UIColor.red
searchIcon.layer.frame = CGRect(x: 0, y: 8, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: 8, width: UIScreen.main.bounds.size.width-28, height: 30)
titleLabel.textColor = UIColor.blue//(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(titleLabel)
titleLabel.text = "Sample Text"
self.navigationItem.titleView = titleContainer
Here is the screenshot of the above code:
Please change the x,y accordingly as per your requirement.
Have you considered making your let bar = UINavigationBar() programmatically and then add it with: self.view.addSubview(bar)?
So you can push all the "UIBarItems" you want..?

Center a UILabel of a UIView

I am currently trying to make a simple pop up, here I have a button, once it gets tapped.
It should show a simple view above it, I achieved the blue background, but I am not being able to add a label to it, and center the label to the blue popup
let width = (sender as! UIButton).frame.width
let y = (sender as! UIButton).frame.origin.y
let x = (sender as! UIButton).frame.origin.x
myView = UIView(frame: CGRect(x: x, y: y - 30, width:width, height: 30))
myView.backgroundColor = UIColor.blue
let label = UILabel()
label.text = (sender as! UIButton).titleLabel?.text
label.font = UIFont(name:"avenirNext-Meduim",size:20)
label.center = self.myView.center
myview.addSubview(label)
self.view.addSubview(myView)
UIView.animate(withDuration: 0.1, delay: 0.1, options: [], animations: {
self.myView.alpha = 0.0
}) { (finished: Bool) in
self.myView.isHidden = true
}
Try to set your label frame:
let label = UILabel(frame: CGRect(origin: .zero, size: yourLabelSize))
Instead of
label.center = self.myView.center
try
label.centerXAnchor.constraint(equalTo: myView.centerXAnchor).isActive = true
label.centerYAnchor.constraint(equalTo: myView.centerYAnchor).isActive = true
after
myview.addSubview(label)
self.view.addSubview(myView)
My solution
let codedLabel:UILabel = UILabel()
codedLabel.frame = CGRect(x: myView.center.x, y: myView.center.y, width: 51, height: 30)
codedLabel.textAlignment = .center
codedLabel.text = "q"
codedLabel.numberOfLines = 1
codedLabel.textColor=UIColor.red
codedLabel.font=UIFont.systemFont(ofSize: 22)
codedLabel.backgroundColor=UIColor.lightGray
self.myView.addSubview(codedLabel)
codedLabel.translatesAutoresizingMaskIntoConstraints = false
codedLabel.heightAnchor.constraint(equalToConstant: 30).isActive = true
codedLabel.widthAnchor.constraint(equalToConstant: 30).isActive = true
codedLabel.centerXAnchor.constraint(equalTo: codedLabel.superview!.centerXAnchor).isActive = true
codedLabel.centerYAnchor.constraint(equalTo: codedLabel.superview!.centerYAnchor).isActive = true
let headerView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: tableView.frame.width, height: 50))
let label = UILabel()
label.frame = CGRect.init(x: headerView.center.x-60, y:headerView.center.y-15, width: 120, height: 30)
label.textAlignment = .center
label.textColor = #colorLiteral(red: 0.1290470958, green: 0.2743584514, blue: 0.6418049335, alpha: 1)
label.font = UIFont(name: "Roboto-Bold", size: 15)
label.text = "11-12-2020"
headerView.addSubview(label)
headerView.backgroundColor = #colorLiteral(red: 0.9967060685, green: 0.9998621345, blue: 0.9997505546, alpha: 1)

Set background color for top safe area only in iOS 11

I'm new to Swift. I have set my top bar programmatically.It works fine for all versions except for iOS version 11.
I want to change the background color of the safe area in iPhone X. Presently I have just added the following code to hide the status bar.
override var prefersStatusBarHidden: Bool {
return true
}
I have created top bar using code:
//Top Bar
let topBar = UIView(frame:CGRect(x: 0,y: 0, width: width, height: 60))
topBar.backgroundColor = UIColor.white
topBar.layer.shadowColor = UIColor.gray.cgColor
topBar.layer.shadowOffset = CGSize(width: 0, height: 3)
topBar.layer.shadowOpacity = 1
topBar.layer.masksToBounds = false
topBar.layer.shadowRadius = 8.0;
//ImageView - Back Button
let backBtn = UIButton(frame:CGRect(x: 25, y: 18, width: 18, height: 34))
let backBtnImage = UIImage(named: "back_button") as UIImage?
backBtn.setImage(backBtnImage, for: .normal)
backBtn.layer.masksToBounds = true
backBtn.addTarget(self,action:#selector(backButtonClicked),
for:.touchUpInside)
//Label - Title
let titleLabel = UILabel(frame:CGRect(x: width * 0.3, y: 13, width: width * 0.55, height: 40))
titleLabel.text = "Favorites"
titleLabel.contentMode = UIViewContentMode.center
//include all in view
topBar.addSubview(titleLabel)
topBar.addSubview(backBtn)
containerView.addSubview(topBar)
Is there a way in which i can do it without using UINavigationBar or setting status bar.
Hi you can also try this one ,
need to add a view with same background which you set in your header view and add to container parent view .
please refer below code
//Top Bar
let safeAreaView = UIView(frame:CGrect(x: 0,y: 0, width: width, height: 40))
safeAreaView.backgroundColor = UIColor.white
self.view.addSubview(safeAreaView)
let topBar = UIView(frame:CGRect(x: 0,y: 0, width: width, height: 60))
topBar.backgroundColor = UIColor.white
topBar.layer.shadowColor = UIColor.gray.cgColor
topBar.layer.shadowOffset = CGSize(width: 0, height: 3)
topBar.layer.shadowOpacity = 1
topBar.layer.masksToBounds = false
topBar.layer.shadowRadius = 8.0;
//ImageView - Back Button
let backBtn = UIButton(frame:CGRect(x: 25, y: 18, width: 18, height: 34))
let backBtnImage = UIImage(named: "back_button") as UIImage?
backBtn.setImage(backBtnImage, for: .normal)
backBtn.layer.masksToBounds = true
backBtn.addTarget(self,action:#selector(backButtonClicked),
for:.touchUpInside)
//Label - Title
let titleLabel = UILabel(frame:CGRect(x: width * 0.3, y: 13, width: width * 0.55, height: 40))
titleLabel.text = "Favorites"
titleLabel.contentMode = UIViewContentMode.center
//include all in view
topBar.addSubview(titleLabel)
topBar.addSubview(backBtn)
containerView.addSubview(topBar)

Auto-resized navigationBar title misplaced

I have a UINavigationBar with a title of variable length. To make sure the title fits without being truncated I've implemented the following code in my viewDidLoad():
let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 40))
titleLabel.text = "\(petsName)'s Day"
titleLabel.font = UIFont.systemFont(ofSize: 30)
titleLabel.backgroundColor = UIColor.clear
titleLabel.textColor = UIColor.white
titleLabel.adjustsFontSizeToFitWidth = true
titleLabel.minimumScaleFactor = 0.5
self.navBar.topItem?.titleView = titleLabel
However, because I have a bar button item, the title is being moved over to the left:
Is there any way to implement the code above but keep the text center aligned within the navigation bar?
Please help me to resolve this issue
Try this.. may be worked
var view = UIView(frame: CGRect(x: 0, y: 0, width: 150, height: 40))
var label = UILabel(frame: CGRect(x: 0, y: 0, width: 150, height: 40))
label.text = "Joys Day"
label.textAlignment = .center
label.font = UIFont.systemFont(ofSize: 30)
view.addSubview(label)
navigationItem?.titleView = view
Change titleLabel width to device width and align it to center. Try this:
let deviceWidth = UIScreen.main.bounds.size.width
let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: deviceWidth, height: 40))
titleLabel.text = "My Test Title"
titleLabel.font = UIFont.systemFont(ofSize: 20)
titleLabel.backgroundColor = UIColor.clear
titleLabel.textColor = UIColor.white
titleLabel.adjustsFontSizeToFitWidth = true
titleLabel.minimumScaleFactor = 0.5
titleLabel.textAlignment = .center
self.navigationItem.titleView = titleLabel
