Adding UITextField on UIView Programmatically Swift

Question

I\'m new to Swift and iOS programming. I was trying to create a UITextField programmatically using Swift but couldn\'t get it quite right. Also how do you change it

Answer 1

Try below code

var textFiled = UITextField(frame: CGRectMake(20.0, 30.0, 100.0, 33.0))
        textFiled.backgroundColor = UIColor.redColor()
        textFiled.borderStyle = UITextBorderStyle.Line
        self.view.addSubview(textFiled)

Answer 2

self.addSubview(myTextField)

Could work only, if you're working with the subclass of UIView .

You have to add it as a subview of the UIView of the ViewController's hierarchy.

var txtField: UITextField = UITextField(frame: CGRect(x: 0, y: 0, width: 500.00, height: 30.00));
self.view.addSubview(txtField)

By default background colour is white, it just might not appear. You need to provide the style as well as text colour and background colour.

txtField.borderStyle = UITextBorderStyle.Line
txtField.text = "myString" 
txtField.backgroundColor = UIColor.redColor()

Answer 3

You can use below code with Swift 5.2:

lazy var titleTextField:UITextField = {
    let textField = UITextField()
    textField.translatesAutoresizingMaskIntoConstraints = false
    textField.placeholder = "Title *"
    textField.keyboardType = UIKeyboardType.default
    textField.returnKeyType = UIReturnKeyType.done
    textField.autocorrectionType = UITextAutocorrectionType.no
    textField.font = UIFont.systemFont(ofSize: 13)
    textField.borderStyle = UITextField.BorderStyle.roundedRect
    textField.clearButtonMode = UITextField.ViewMode.whileEditing;
    textField.contentVerticalAlignment = UIControl.ContentVerticalAlignment.center
    return textField
}()

Answer 4

Add the textField on UIView is

var textField=UITextField(frame:CGRectMake(x,y,width,height));
self.view.addSubView(textField)

Answer 5

Write the code in viewDidLoad() and implement delegate UITextFieldDelegate

let _textField: UITextField = UITextField(frame: CGRect(x: 0, y: 0, width: 200.00, height: 40.00))
_textField.backgroundColor = UIColor.redColor()
_textField.text = "some string"
_textField.delegate = self
_textField.borderStyle = UITextBorderStyle.Line
self.view.addSubview(_textField)

Answer 6

Updated for Swift 3 and Xcode 8.2

    let stepsTextField = UITextField(frame: CGRect(x: 20, y: 100, width: 300, height: 40))
    stepsTextField.placeholder = "Enter text here"
    stepsTextField.font = UIFont.systemFont(ofSize: 15)
    stepsTextField.borderStyle = UITextBorderStyle.roundedRect
    stepsTextField.autocorrectionType = UITextAutocorrectionType.no
    stepsTextField.keyboardType = UIKeyboardType.default
    stepsTextField.returnKeyType = UIReturnKeyType.done
    stepsTextField.clearButtonMode = UITextFieldViewMode.whileEditing;
    stepsTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.center
