我创建的应用程序不适用于 iOS 9。
import UIKit
class WebViewController: UIViewController, UIWebViewDelegate {
@IBOutlet var webView: UIWebView!
override func viewDidLoad()
{
super.viewDidLoad()
// Do any additional setup after loading the view.
let requestURL = NSURL(string:"http://stackoverflow.com")
let request = NSURLRequest(URL: requestURL!)
webView.loadRequest(request)
webView.delegate = self
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func webViewDidStartLoad(webView: UIWebView)
{
print("Load started")
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}
func webViewDidFinishLoad(webView: UIWebView)
{
print("Load finished")
UIApplication .sharedApplication().networkActivityIndicatorVisible = false
}
func webView(webView: UIWebView, didFailLoadWithError error: NSError?)
{
print("Error = ", error)
}
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool
{
print("URl ", request.URL?.absoluteString)
return true
}
}
