In this code snipped demonstrates how to:

  • Create UIWebView programmatically
  • Implement UIWebViewDelegate functions webViewDidStartLoad and webViewDidFinishLoad
  • Make UIWebView display HTML Code

import UIKit

class ViewController: UIViewController, UIWebViewDelegate {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        let myWebView:UIWebView = UIWebView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height))
        
        self.view.addSubview(myWebView)
        
        myWebView.delegate = self
        
        let htmlString:String = "Bold string"
        myWebView.loadHTMLString(htmlString, baseURL: nil)
        
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    
    func webViewDidStartLoad(_ webView: UIWebView)
    {
        
    }
    func webViewDidFinishLoad(_ webView: UIWebView)
    {
        
    }
    
}
