I want to make a reusable UILabel and UITextField so it will not be repeated, how I can do that? this is my code
let nameLabel: UILabel = {
let label = UILabel()
label.text = "Name"
label.textColor = .white
return label
}()
let nameTextField: UITextField = {
let tv = UITextField()
tv.placeholder = "Name"
tv.textColor = #colorLiteral(red: 0.6078431373, green: 0.6078431373, blue: 0.6078431373, alpha: 1)
return tv
}()
let emailLabel: UILabel = {
let label = UILabel()
label.text = "Email"
label.textColor = .white
return label
}()
let emailTextField: UITextField = {
let tv = UITextField()
tv.placeholder = "Email"
tv.textColor = #colorLiteral(red: 0.6078431373, green: 0.6078431373, blue: 0.6078431373, alpha: 1)
return tv
}()
Use computed property , it'll return a new instance every access
var emailLabel: UILabel {
let label = UILabel()
label.text = "Default"
label.textColor = .green
view.addSubview(label)
return label
}
let em1 = emailLabel
em1.text = "dshjsdhdshdhdshjdsh"
em1.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
let em2 = emailLabel
em2.text = "dshjsdhdshdhdshjdsh"
em2.frame = CGRect(x: 0, y: 100, width: 100, height: 100)

How can I make this text using single UILabel or give any other solution to achieve this design.
You can use NSTextAttachment for that behaviour. I modify this for position of attachment.
All code :
#IBOutlet weak var lbl: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let string = "Urban points users average montly saving is "
let normalNameString = NSMutableAttributedString.init(string: string)
let attachment = NSTextAttachment()
attachment.image = imageHelper.pgImage(textValue: "QAR 115 ", lbl: lbl)
attachment.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment.image!.size.height).rounded() / 2, width: attachment.image!.size.width, height: attachment.image!.size.height)
normalNameString.append(NSAttributedString(attachment: attachment))
normalNameString.append(NSAttributedString(string: "You have saved "))
let attachment2 = NSTextAttachment()
attachment2.image = imageHelper.pgImage(textValue: "QAR 29",textColor: UIColor.yellow,backgroundColor: UIColor.black , lbl: lbl)
attachment2.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment2.image!.size.height).rounded() / 2, width: attachment2.image!.size.width, height: attachment2.image!.size.height)
normalNameString.append(NSAttributedString(attachment: attachment2))
normalNameString.append(NSAttributedString(string: " this month"))
lbl.attributedText = normalNameString
}
}
class imageHelper{
static func pgImage(textValue:String,textColor : UIColor = UIColor.white , backgroundColor : UIColor = UIColor.red,lbl : UILabel) ->UIImage{
let label = UILabel(frame: CGRect(x: 0, y: 0, width: (textValue as NSString).size(withAttributes: [NSAttributedString.Key.font : lbl.font!]).width, height: lbl.frame.size.height))
label.font = lbl.font
label.textAlignment = .center
label.textColor = textColor
label.backgroundColor = backgroundColor
label.layer.borderColor = UIColor.darkGray.cgColor
label.layer.borderWidth = 1
label.layer.cornerRadius = label.frame.size.height/2
label.layer.masksToBounds = true
label.text = textValue
label.numberOfLines = 1
UIGraphicsBeginImageContextWithOptions(label.bounds.size, false,UIScreen.main.scale)
label.layer.render(in: UIGraphicsGetCurrentContext()!)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image!
}
}
And the result is :
I am trying to add CALayer in my view, layer is shown but text is hide.
My code is as follow:
let label = UILabel(frame: CGRect(x: 100, y: 100, width: 25, height: 25))
label.text = "5"
label.font = .boldSystemFont(ofSize: 10)
label.adjustsFontSizeToFitWidth = true
label.textColor = #colorLiteral(red: 0.4392156899, green: 0.01176470611, blue: 0.1921568662, alpha: 1)
label.textAlignment = .center
let sublayer = label.layer
sublayer.backgroundColor = UIColor.yellow.cgColor
sublayer.borderColor = UIColor.red.cgColor
self.view.layer.addSublayer(sublayer)
Can you please let me know where I am going wrong?
Thank you,
I'm trying to achieve UITextField editing or not editing style like this:
But the trickiest part for me is How to change that left image tint color. I have achieved this so far:
My code:
UITextField
lazy var email: UITextField = {
let name = UITextField()
name.layer.cornerRadius = 17.5
name.layer.borderColor = UIColor(red: 0.55, green: 0.61, blue: 0.69, alpha: 0.5).cgColor
name.layer.borderWidth = 1.5
name.placeholder = "Email"
name.font = UIFont.systemFont(ofSize: 15)
name.textColor = UIColor(red: 0.55, green: 0.61, blue: 0.69, alpha: 1)
name.backgroundColor = .clear
name.leftViewMode = UITextFieldViewMode.always
name.delegate = self
name.translatesAutoresizingMaskIntoConstraints = false
return name
}()
leftImage func:
func addLeftImageTo(txtField: UITextField, andImage img: UIImage) {
let leftView = UIView(frame: CGRect(x: 0, y: 0, width: 42.75, height: 40))
let centerX: CGFloat = (leftView.frame.midX) - (img.size.width / 2)
let centerY: CGFloat = (leftView.frame.midY) - (img.size.height / 2)
let leftImageView = UIImageView(frame: CGRect(x: centerX + 2 , y: centerY - 1, width: img.size.width, height: img.size.height))
leftImageView.contentMode = .scaleAspectFit
leftImageView.image = img
leftView.addSubview(leftImageView)
txtField.leftView = leftView
txtField.leftViewMode = .always
}
Adding leftImages:
let emailLeftImg = UIImage(named: "ic_txt_field_email")
addLeftImageTo(txtField: email, andImage: emailLeftImg!)
let passwordLeftImg = UIImage(named: "ic_txt_field_password")
addLeftImageTo(txtField: password, andImage: passwordLeftImg!)
editingBegains and Ending:
func textFieldDidBeginEditing(_ textField: UITextField) {
self.setTextBorder(textField: textField, color: UIColor.white, borderColor: UIColor.white, isSelected: true)
}
func textFieldDidEndEditing(_ textField: UITextField) {
self.setTextBorder(textField: textField, color: UIColor.clear, borderColor: UIColor(red: 0.55, green: 0.61, blue: 0.69, alpha: 0.5), isSelected: false)
}
func setTextBorder(textField: UITextField, color: UIColor, borderColor: UIColor, isSelected: Bool) {
textField.backgroundColor = color
textField.layer.borderColor = borderColor.cgColor
textField.tintColor = UIColor(red: 1.0, green: 0.2, blue: 0.33, alpha: 1)
textField.layer.masksToBounds = false
if isSelected == true {
textField.layer.shadowRadius = 3.0
textField.layer.shadowColor = UIColor.black.cgColor
textField.layer.shadowOffset = CGSize(width: 0, height: 2)
textField.layer.shadowOpacity = 0.125
} else {
textField.layer.shadowRadius = 0
textField.layer.shadowColor = UIColor.clear.cgColor
textField.layer.shadowOffset = CGSize(width: 0, height: 0)
textField.layer.shadowOpacity = 0
}
}
I had tried adding this code to change Image color but it didn't work.
var picTintColor: Bool = false
In LeftImage func:
if picTintColor == true {
leftImageView.image = img.withRenderingMode(.alwaysTemplate)
leftImageView.tintColor = .blue
} else {
leftImageView.image = img
}
And in editingBegains and Ending func:
if isSelected == true {
picTintColor = true
} else {
picTintColor = false
}
I'm a complete noob in IOS programming so thanks for your patience and sorry for my bad english. Thanks!
According the code ,it actually can not pass isSelected signal to the leftImageView,maybe leftImageView get in laster is not the earlier ,or the signal not pass successly.
I suggest that a easy way to do, just in editingBegains and Ending: to do what you want change the imageview,like this:
func textFieldDidBeginEditing(_ textField: UITextField) {
let emailLeftImg = UIImage(named: "ic_txt_field_email")
addLeftImageTo(txtField: email, andImage: emailLeftImg!)
}
func addLeftImageTo(txtField: UITextField, andImage img: UIImage) {
let leftView = UIView(frame: CGRect(x: 0, y: 0, width: 42.75, height: 40))
let centerX: CGFloat = (leftView.frame.midX) - (img.size.width / 2)
let centerY: CGFloat = (leftView.frame.midY) - (img.size.height / 2)
let leftImageView = UIImageView(frame: CGRect(x: centerX + 2 , y: centerY - 1, width: img.size.width, height: img.size.height))
leftImageView.contentMode = .scaleAspectFit
if picTintColor == true {
leftImageView.image = img.withRenderingMode(.alwaysTemplate)
leftImageView.tintColor = .blue
} else {
leftImageView.image = img
}
leftView.addSubview(leftImageView)
txtField.leftView = leftView
txtField.leftViewMode = .always
}
and in end delgate method ,just do that ,you can try this way to test.Hope to help you.
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)
im trying to add an icon to my username textfield, somehow I added the icon but I cant add any padding to it.
What I mean is, I want it to look like this:
And what I get is this:
let usernameTextField: UITextField = {
let tf = UITextField()
let imageView = UIImageView()
let image = UIImage(named: "user-icon")
imageView.image = image
imageView.frame = CGRect(x: 0, y: 0, width: 10, height: 15)
tf.leftViewMode = UITextFieldViewMode.always
tf.leftView = imageView
tf.addSubview(imageView)
var placeholder = NSMutableAttributedString(string: "username", attributes: [NSForegroundColorAttributeName: UIColor.lightGray])
tf.attributedPlaceholder = placeholder
tf.backgroundColor = UIColor.rgb(red: 34, green: 34, blue: 34)
tf.borderStyle = .roundedRect
tf.font = UIFont.systemFont(ofSize: 14)
tf.layer.cornerRadius = 25
tf.textColor = .white
tf.layer.borderWidth = 1
tf.layer.borderColor = UIColor(white: 1, alpha: 0.1).cgColor
tf.layer.masksToBounds = true
return tf
}()
And this is my code block. Even if I change the x and y values it doesnt event move any pixels.
Increase the width of the view and center the image. Adjust the width accordingly (I have set it 50). Try this ...
let usernameTextField: UITextField = {
let tf = UITextField()
let imageView = UIImageView()
let image = UIImage(named: "user-icon")
imageView.image = image
imageView.frame = CGRect(x: 0, y: 0, width: 50, height: 15)
imageView.contentMode = .scaleAspectFit
tf.leftViewMode = UITextFieldViewMode.always
tf.leftView = imageView
tf.addSubview(imageView)
var placeholder = NSMutableAttributedString(string: "username", attributes: [NSForegroundColorAttributeName: UIColor.lightGray])
tf.attributedPlaceholder = placeholder
tf.backgroundColor = UIColor.init(red: 35.0/100.0, green: 34.0/100.0, blue: 34.0/100.0, alpha: 1)
tf.borderStyle = .roundedRect
tf.font = UIFont.systemFont(ofSize: 14)
tf.layer.cornerRadius = 25
tf.textColor = .white
tf.layer.borderWidth = 1
tf.layer.borderColor = UIColor(white: 1, alpha: 0.1).cgColor
tf.layer.masksToBounds = true
return tf
}()
