In this short Swift code example, you will learn how to create and customize UITextView programmatically in Swift.
- Create UITextView programmatically
- Position UITextView at the center of the view
- Change UITextView background colour
- Create UITapGestureRecognizer
- Add UITapGestureRecognizer to main view
- Add UITextView as a subview
- Create a function to handle Tap away event
import UIKit class ViewController: UIViewController, UITextFieldDelegate { override func viewDidLoad() { super.viewDidLoad() } override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) 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.boldSystemFont(ofSize: 20) textView.font = UIFont(name: "Verdana", size: 17) // Capitalize all characters user types textView.autocapitalizationType = UITextAutocapitalizationType.allCharacters // Make UITextView web links clickable textView.isSelectable = true textView.isEditable = false textView.dataDetectorTypes = UIDataDetectorTypes.link // Make UITextView corners rounded textView.layer.cornerRadius = 10 // Enable auto-correction and Spellcheck textView.autocorrectionType = UITextAutocorrectionType.yes textView.spellCheckingType = UITextSpellCheckingType.yes // myTextView.autocapitalizationType = UITextAutocapitalizationType.None // Make UITextView Editable textView.isEditable = true self.view.addSubview(textView)} }
