I have been making search bars without navigation on the imageView.
The search bar height is fixed but i want to change the search bar height.
so i tried
let frame = CGRect(x: 0, y: 0, width: 100, height: 44)
searchbar.frame = frame
and
searchbar.heightAnchor.constraint(equalToConstant: 200).isActive = true
but they don't work.
I'm using this code
searchBar.isTranslucent = true
searchBar.searchBarStyle = .minimal
so like this
please help me change the search bar textfield height.
fileprivate func customizeSearchField(){
UISearchBar.appearance().setSearchFieldBackgroundImage(UIImage(), for: .normal)
searchField.backgroundColor = .white
if let searchTextField = searchField.value(forKey: "searchField") as? UITextField {
searchTextField.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
searchTextField.heightAnchor.constraint(equalToConstant: 50),
searchTextField.leadingAnchor.constraint(equalTo: searchField.leadingAnchor, constant: 10),
searchTextField.trailingAnchor.constraint(equalTo: searchField.trailingAnchor, constant: -10),
searchTextField.centerYAnchor.constraint(equalTo: searchField.centerYAnchor, constant: 0)
])
searchTextField.clipsToBounds = true
searchTextField.font = GenericUtility.getOpenSansRegularFontSize(14)
searchTextField.layer.cornerRadius = 4.0
searchTextField.layer.borderWidth = 1.0
searchTextField.layer.borderColor = AppColor.primaryLightGray.cgColor
}
}
try this!
for myView in searchBars.subviews {
for mySubView in myView.subviews {
if let textField = mySubView as? UITextField {
var bounds: CGRect
bounds = textField.frame
bounds.size.height = 40 //(set your height)
textField.bounds = bounds
textField.borderStyle = UITextBorderStyle.RoundedRect
}
}
}
Try this:
searchBar.frame.size.height = 44
if you want to use with interface builder:
class MediaSearchBar: UISearchBar {
override func layoutSubviews() {
}
}
and setup it in viewDidLoad:
func setupSearchBar() {
searchBar.delegate = self
for myView in searchBar.subviews {
for mySubView in myView.subviews {
if let textField = mySubView as? UITextField {
textField.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
textField.heightAnchor.constraint(equalTo: myView.heightAnchor,
multiplier: 1.0, constant: -20.0),
textField.leadingAnchor.constraint(equalTo: myView.leadingAnchor, constant: 10.0),
textField.trailingAnchor.constraint(equalTo: myView.trailingAnchor, constant: -10.0),
textField.centerYAnchor.constraint(equalTo: myView.centerYAnchor, constant: 0.0)
])
textField.clipsToBounds = true
}
}
}
}

I am working on a canvas view where I am trying to add image to a UIView and a text to a UIView, on satisfying some conditions.
The issue is, I am not able to add label to my UIView after satisfying the required condition. I tried this code separately without any functions and conditions and it is working fine. But if I try and run it as given below it doesn't show me the label on the UIView.
[Note- The code here is working fine for imageView.]
I tried various constraint combinations like, centerX, centerY, width, height or leading, trailing, top, bottom. But nothing is working. Please help.
My code is as below: -
class CanvasViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
createCanvasOnAspectRatio()
}
func createCanvasOnAspectRatio() {
let View1: UIView = {
let viewView = UIView()
viewView.translatesAutoresizingMaskIntoConstraints = false
viewView.contentMode = .scaleAspectFit
print(UserDefaults.standard.bool(forKey: "backgroundColourSelected"))
if UserDefaults.standard.bool(forKey: "backgroundColourSelected") {
viewView.backgroundColor = self.viewColor
}else {
viewView.backgroundColor = .white
}
viewView.clipsToBounds = true
return viewView
}()
self.canvasView.addSubview(View1)
View1.centerXAnchor.constraint(equalTo: canvasView.centerXAnchor, constant: 0).isActive = true
View1.centerYAnchor.constraint(equalTo: canvasView.centerYAnchor, constant: 0).isActive = true
View1.widthAnchor.constraint(equalTo: canvasView.widthAnchor, constant: 0).isActive = true
View1.heightAnchor.constraint(equalTo: canvasView.widthAnchor, multiplier: aspectRatio).isActive = true
if UserDefaults.standard.bool(forKey: "imageSelectedFromGallexy") == true {
for item in 0..<self.imagesForGallery.count {
let image = imagesForGallery[item]
let image_View: UIImageView = {
let imageV = UIImageView()
imageV.image = image
imageV.contentMode = .scaleAspectFill
imageV.translatesAutoresizingMaskIntoConstraints = false
imageV.clipsToBounds = true
return imageV
}()
View1.addSubview(image_View)
image_View.topAnchor.constraint(equalTo: View1.topAnchor, constant: 0).isActive = true
image_View.bottomAnchor.constraint(equalTo: View1.bottomAnchor, constant: 0).isActive = true
image_View.leadingAnchor.constraint(equalTo: View1.leadingAnchor, constant: 0).isActive = true
image_View.trailingAnchor.constraint(equalTo: View1.trailingAnchor, constant: 0).isActive = true
}
}
if UserDefaults.standard.bool(forKey: "addTextToCanvas") == true {
let labelTextView: UILabel = {
let labelView = UILabel()
//labelView.frame = CGRect(x: 0.0, y: 0.0, width: 50.0, height: 30.0)

labelView.textColor = .green
labelView.text = "Hello"
labelView.font = UIFont(name: "Avenir-Medium", size: 15.0)

// labelView.clipsToBounds = true
return labelView
}()

labelTextView.centerYAnchor.constraint(equalTo: View1.centerYAnchor, constant: 0).isActive = true
labelTextView.widthAnchor.constraint(equalTo: View1.widthAnchor, constant: 0).isActive = true
labelTextView.heightAnchor.constraint(equalTo: View1.widthAnchor, multiplier: 1.0).isActive = true
UserDefaults.standard.set(false, forKey: "addTextToCanvas")
}
}
}
I am trying to make a text acceptor view like Instagram and Snapchat.
I am trying to add a UITextview (programatically) inside a UIView thats also added programatically. Below is the code I am trying to use to add the UITextView, but it is not working when added with UIView code. Please help.
What I am trying to achieve is:
import UIKit
class TextViewViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let View1: UIView = {
let viewView = UIView()
viewView.translatesAutoresizingMaskIntoConstraints = false
viewView.contentMode = .scaleAspectFit
viewView.backgroundColor = .red
viewView.clipsToBounds = true
return viewView
}()
self.view.addSubview(View1)
View1.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 0).isActive = true
View1.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 0).isActive = true
View1.topAnchor.constraint(equalTo: view.topAnchor, constant: 250).isActive = true
View1.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -250).isActive = true
let textView = UITextView(frame: CGRect(x: 20.0, y: 90.0, width: 250.0, height: 100.0))
textView.contentInsetAdjustmentBehavior = .automatic
textView.center = self.view.center
textView.textAlignment = NSTextAlignment.justified
textView.backgroundColor = UIColor.lightGray
// Use RGB colour
textView.backgroundColor = UIColor(red: 39/255, green: 53/255, blue: 182/255, alpha: 1)
// Update UITextView font size and colour
textView.font = UIFont.systemFont(ofSize: 20)
textView.textColor = UIColor.white
textView.font = UIFont(name: "Verdana", size: 17)
// Make UITextView web links clickable
textView.isSelectable = true
textView.isEditable = false
textView.dataDetectorTypes = UIDataDetectorTypes.link
// Make UITextView corners rounded
textView.layer.cornerRadius = 10
// Make UITextView Editable
textView.isEditable = true
View1.addSubview(textView)
//
// let textView: UITextView = {
// let tv = UITextView(frame: CGRect(x: 20.0, y: 90.0, width: 100.0, height: 50.0))
// tv.contentInsetAdjustmentBehavior = .automatic
// tv.center = self.view.center
// tv.textAlignment = NSTextAlignment.justified
// tv.textColor = UIColor.blue
// tv.backgroundColor = UIColor.lightGray
// return tv
// }()
//
// View1.addSubview(textView)
// textView.topAnchor.constraint(equalTo: View1.topAnchor, constant: 20).isActive = true
// textView.bottomAnchor.constraint(equalTo: View1.bottomAnchor, constant: 20).isActive = true
// textView.leadingAnchor.constraint(equalTo: View1.leadingAnchor, constant: 0).isActive = true
// textView.trailingAnchor.constraint(equalTo: View1.trailingAnchor, constant: 0).isActive = true
}
}
The issue is in the next line of code
textView.center = self.view.center
Get rid of it and you will see the textView in the view hierarchy
I have spent a while trying to figure this out, but I just can't. There is probably something really simple I am missing here. I am trying to animate a view coming in from the bottom. This si the code I am using for the view:
private let undoView: UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
view.backgroundColor = .white
view.layer.cornerRadius = 15
view.layer.shadowOffset = .zero
view.layer.shadowOpacity = 0.3
view.layer.shadowRadius = 5
view.layer.shouldRasterize = true
view.layer.rasterizationScale = UIScreen.main.scale
let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle("Undo", for: .normal)
button.titleLabel?.textAlignment = .center
button.setTitleColor(.systemBlue, for: .normal)
let buttonConstraints = [
button.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 16),
button.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -16),
button.topAnchor.constraint(equalTo: view.topAnchor, constant: 16),
button.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -16)
]
view.addSubview(button)
NSLayoutConstraint.activate(buttonConstraints)
let swipeGesture = UISwipeGestureRecognizer(target: view, action: #selector(undoViewSwiped))
view.addGestureRecognizer(swipeGesture)
return view
}()
And this is the code I am using to try and achieve the animation:
func addUndoView() {
var bottomConstraint = undoView.topAnchor.constraint(equalTo: view.bottomAnchor, constant: 0)
let constraints = [
undoView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
undoView.widthAnchor.constraint(equalToConstant: view.bounds.width / 3),
bottomConstraint,
undoView.heightAnchor.constraint(equalToConstant: 50)
]
view.addSubview(undoView)
NSLayoutConstraint.activate(constraints)
undoView.layoutIfNeeded()
bottomConstraint.isActive = false
bottomConstraint = undoView.topAnchor.constraint(equalTo: view.layoutMarginsGuide.bottomAnchor, constant: -58)
bottomConstraint.isActive = true
UIView.animate(withDuration: 0.5, delay: 0.2, animations: {
self.undoView.layoutIfNeeded()
})
}
I want the view to just be created underneath the visible view, and then slide up to 8 above the bottom layout margin. This code however just makes the view 'expand' at its final position instead of coming into view from the bottom. Using self.view.layoutIfNeeded() makes the view fly in from the top left of the screen, for some reason.
good day I usually work with transform property for move one view from x position to y portion, please check this example.
class ViewController: UIViewController {
let button : UIButton = {
let button = UIButton(type: .custom)
button.setTitle("Button", for: .normal)
button.backgroundColor = .gray
button.translatesAutoresizingMaskIntoConstraints = false
return button
}()
let customView : UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
view.backgroundColor = .red
return view
}()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
view.addSubview(button)
view.addSubview(customView)
NSLayoutConstraint.activate([
button.centerYAnchor.constraint(equalTo: self.view.centerYAnchor),
button.centerXAnchor.constraint(equalTo: self.view.centerXAnchor),
customView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),
customView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
customView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
customView.heightAnchor.constraint(equalToConstant: 100)
])
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
setupAnimationCustomView()
}
private func setupAnimationCustomView(){
UIView.animate(withDuration: 1, delay: 0 , options: .curveEaseOut, animations: {
print(self.button.frame.origin.y)
let translationY = self.view.frame.height - self.button.frame.origin.y - self.button.frame.height - self.customView.frame.height - 8
self.customView.transform = CGAffineTransform(translationX: 0, y: translationY * (-1))
}, completion: nil)
}
}
on the animation I calculate the distance that I need to move my customView.
I habe a tableView with a footerView. It should display a simple label.
In my ViewController, in viewDidLoad, I assign the tableFooterView like so:
let footerView = MyFooterView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 0))
tableView.tableFooterView = footerView
MyFooterView is a UIView with a single label. The label setup looks like so:
label.font = someFont
label.adjustsFontForContentSizeCategory = true
label.textColor = .black
label.numberOfLines = 0
label.text = "my super looooooong label that should break some lines but it doesn't."
label.textAlignment = .center
label.translatesAutoresizingMaskIntoConstraints = false
addSubview(label)
NSLayoutConstraint.activate([
label.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 40),
label.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -40),
label.topAnchor.constraint(equalTo: self.topAnchor, constant: 20),
label.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: -20)
])
In order to get AutoLayout to work with MyFooterView, I call this method inside UIViewControllers viewDidLayoutSubviews:
func sizeFooterToFit() {
if let footerView = self.tableFooterView {
footerView.setNeedsLayout()
footerView.layoutIfNeeded()
let height = footerView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize).height
var frame = footerView.frame
frame.size.height = height
footerView.frame = frame
self.tableFooterView = footerView
}
}
Problem: The lines in the label do not break. I get the following result:
What can I do so that the label has multiple lines? AutoLayout is working thanks to the method sizeFooterToFit. The only thing is that the labels height is only as high as a single line.
HERE is the way how you can achieve it for tableHeaderView and with your case you just need to add below code in your UIViewController class
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
tbl.updateHeaderViewHeight()
}
And Helper extension
extension UITableView {
func updateHeaderViewHeight() {
if let header = self.tableFooterView {
let newSize = header.systemLayoutSizeFitting(CGSize(width: self.bounds.width, height: 0))
header.frame.size.height = newSize.height
}
}
}
And remove
func sizeFooterToFit() {
if let footerView = self.tableFooterView {
footerView.setNeedsLayout()
footerView.layoutIfNeeded()
let height = footerView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize).height
var frame = footerView.frame
frame.size.height = height
footerView.frame = frame
self.tableFooterView = footerView
}
}
Above code.
And result will be:
I'm trying to create a keyboard accessory view programmatically. I've set up a container view and inside that I'm trying to set up a textfield, post button, and an emoji.
Here's an example of what I'm trying to make.
Click here to view the image.
Here's the code that I am working with. I think the problem is when I'm setting the constraints.
Couple of questions running through my mind are:
Do I need to set up constraints for the container view?
How do I add appropriate constraints to the textfield?
override var inputAccessoryView: UIView? {
get {
//Set up the container
let containerView = UIView()
containerView.backgroundColor = #colorLiteral(red: 0.9784782529, green: 0.9650371671, blue: 0.9372026324, alpha: 1)
containerView.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 60)
let textField = UITextField()
textField.placeholder = "Add a reframe..."
textField.isSecureTextEntry = false
textField.textAlignment = .left
textField.borderStyle = .none
textField.translatesAutoresizingMaskIntoConstraints = false
textField.translatesAutoresizingMaskIntoConstraints = false
textField.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
textField.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
textField.bottomAnchor.constraint(equalTo: containerView.bottomAnchor).isActive = true
textField.topAnchor.constraint(equalTo: containerView.topAnchor).isActive = true
textField.heightAnchor.constraint(equalToConstant: 50)
containerView.addSubview(textField)
return containerView
}
}
This is the error that I keep getting.
*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to activate constraint with anchors and because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal.'

InputAccessoryView working:
Click here
TextView expansion:
Click here.
Before applying constraints view should be in view hierarchy or error which you got will be raised. To get rid of error just do containerView.addSubview(textField) after let textField = UITextField().
Regarding example image you posted, initial solution could be something like this
override var inputAccessoryView: UIView? {
get {
//Set up the container
let containerView = UIView()
containerView.backgroundColor = #colorLiteral(red: 0.9784782529, green: 0.9650371671, blue: 0.9372026324, alpha: 1)
containerView.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 60)
let textField = UITextField()
containerView.addSubview(textField)
textField.translatesAutoresizingMaskIntoConstraints = false
textField.placeholder = "Add a reframe..."
textField.textAlignment = .left
textField.backgroundColor = .white
textField.layer.cornerRadius = 50/2
textField.layer.masksToBounds = true
textField.borderStyle = .none
textField.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 8).isActive = true
textField.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -5).isActive = true
textField.topAnchor.constraint(equalTo: containerView.topAnchor, constant: 10).isActive = true
textField.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 15, height: textField.frame.height)) // adding left padding so it's not sticked to border
textField.leftViewMode = .always
let arrow = UIImageView(image: #imageLiteral(resourceName: "arrowUp"))
containerView.addSubview(arrow)
arrow.translatesAutoresizingMaskIntoConstraints = false
arrow.trailingAnchor.constraint(equalTo: textField.trailingAnchor, constant: -10).isActive = true
arrow.centerYAnchor.constraint(equalTo: textField.centerYAnchor).isActive = true
let button = UIButton()
containerView.addSubview(button)
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle("🤗", for: .normal)
button.contentEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
button.leadingAnchor.constraint(equalTo: textField.trailingAnchor, constant: 10).isActive = true
button.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -8).isActive = true
button.centerYAnchor.constraint(equalTo: textField.centerYAnchor).isActive = true
// Negative values for constraints can be avoided if we change order of views when applying constrains
// f.e. instead of button.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -8).isActive = true
// write containerView.trailingAnchor.constraint(equalTo: button.trailingAnchor, constant: 8).isActive = true
return containerView
}
}
