我正在处理以下代码,并尝试在页面加载时在视图中显示活动指标.
我试图实现WKNavigationDelegate方法,但是我没有显示出来.
关于如何解决这个问题的任何建议？
我没有在任何地方设置SupportWebView视图委托,但我不知道如何在swift ..
import UIKit
import WebKit
class SupportWebView: UIViewController,WKNavigationDelegate {
@IBOutlet var containerView : UIView? = nil
var webView: WKWebView?
override func loadView() {
super.loadView()
self.webView = WKWebView()
self.view = self.webView
}
override func viewDidLoad() {
super.viewDidLoad()
var dataManager = DataManager.sharedDataManager()
var url = dataManager.myValidURL
var req = NSURLRequest(URL:url!)
self.webView!.loadRequest(req)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func webView(webView: WKWebView,didStartProvisionalNavigation navigation: WKNavigation!) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}
func webView(webView: WKWebView,didFinishNavigation navigation: WKNavigation!) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
}
解决方法
已经评论过,你忘了设置webView代理：
override func loadView() {
super.loadView()
self.webView = WKWebView()
self.webView.navigationDelegate = self
self.view = self.webView
}
