从UIWebView打开Safari中的链接

import UIKit

class ViewController: UIViewController, UIWebViewDelegate {
    @IBOutlet weak var webView: UIWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置UIWebView的代理对象
        webView.delegate = self
        
        // 加载网页
        if let url = URL(string: "https://example.com") {
            let request = URLRequest(url: url)
            webView.loadRequest(request)
        }
    }
    
    // UIWebViewDelegate方法：用户点击链接时进行处理
    func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
        // 判断链接的scheme是否为http或https
        if let scheme = request.url?.scheme, scheme == "http" || scheme == "https" {
            // 在Safari中打开链接
            UIApplication.shared.open(request.url!, options: [:], completionHandler: nil)
            return false
        }
        return true
    }
