Rich Text Rendering Simplified with AttributedTextView Library
Creating an appealing and user-friendly text display is a crucial aspect of iOS application development. The open-source library, AttributedTextView, offers a streamlined approach to constructing rich text views within iOS applications. This library not only supports a wide array of text attributes such as fonts, font sizes, colors, background colors, hyperlinks, and images, but also facilitates custom text formatting. Moreover, it's updated to work seamlessly with the latest APIs of iOS 15.
Let's delve into some practical examples to showcase how AttributedTextView can be utilized:
Basic Usage
import UIKit
import AttributedTextView
class ViewController: UIViewController {
@IBOutlet weak var textView: AttributedTextView!
override func viewDidLoad() {
super.viewDidLoad()
// Creating attributed text
let attributedText = NSMutableAttributedString(string: "This is a simple attributed text view.")
attributedText.addAttribute(.font, value: UIFont.systemFont(ofSize: 20), range: NSRange(location: 0, length: attributedText.length))
attributedText.addAttribute(.foregroundColor, value: UIColor.black, range: NSRange(location: 0, length: attributedText.length))
// Setting the attributed text
textView.attributedText = attributedText
}
}
Custom Rich Text
import UIKit
import AttributedTextView
class ViewController: UIViewController {
@IBOutlet weak var textView: AttributedTextView!
override func viewDidLoad() {
super.viewDidLoad()
// Creating attributed text
let attributedText = NSMutableAttributedString(string: "This is a simple attributed text view.")
attributedText.addAttribute(.font, value: UIFont.systemFont(ofSize: 20), range: NSRange(location: 0, length: attributedText.length))
attributedText.addAttribute(.foregroundColor, value: UIColor.black, range: NSRange(location: 0, length: attributedText.length))
// Setting a hyperlink
attributedText.addAttribute(.link, value: URL(string: "https://www.example.com/"), range: NSRange(location: 5, length: 10))
// Inserting an image
let image = UIImage(named: "image.png")
attributedText.addAttribute(.image, value: image, range: NSRange(location: 20, length: 10))
// Applying underline
attributedText.addAttribute(.underlineStyle, value: NSUnderlineStyle.single, range: NSRange(location: 30, length: 10))
// Setting background color
attributedText.addAttribute(.backgroundColor, value: UIColor.red, range: NSRange(location: 40, length: 10))
// Setting the attributed text
textView.attributedText = attributedText
}
}
