我的UIWebView不會加載,我非常困惑。爲什麼.Webview在幾個星期前工作。它所鏈接的網站得到更新。但由於某種原因,現在我發送給它的任何鏈接都不起作用。我試圖清除緩存。我有點失落,爲什麼這不會出現。我的手機上的互聯網工作正常。故事板中的所有內容都正確連接。Swift中的UIWebView問題
活動指標保持旋轉。而我的警報是從應該發生的didFailLoadWithError出現的,但是找出爲什麼它不會連接會很好。任何幫助都會很棒,謝謝。
class CommunityViewController: UIViewController, UIWebViewDelegate {
@IBOutlet weak var activityIndicator: UIActivityIndicatorView!
@IBOutlet weak var communityWeb: UIWebView!
var refreshControl:UIRefreshControl!
let url = "http://www.google.com"
override func viewWillAppear(animated: Bool) {
NSURLCache.sharedURLCache().removeAllCachedResponses()
NSURLCache.sharedURLCache().diskCapacity = 0
NSURLCache.sharedURLCache().memoryCapacity = 0
}

super.viewDidLoad()
self.communityWeb.delegate = self

self.refreshControl.attributedTitle = NSAttributedString(string: "")
self.refreshControl.addTarget(self, action: "refresh:", forControlEvents: UIControlEvents.ValueChanged)

func webViewDidStartLoad(webView: UIWebView) // here show your indicator

self.activityIndicator.hidesWhenStopped = true
self.communityWeb.scrollView.contentSize.width = self.communityWeb.frame.size.width
}
func webView(webView: UIWebView, didFailLoadWithError error: NSError?) {
let alertView = SIAlertView(title: "Internet Connection", andMessage: "Connect to the internet to receive latest updates from the Community")
alertView.addButtonWithTitle("OK", type: SIAlertViewButtonType.Default, handler:
{alertView in

})
alertView.transitionStyle = SIAlertViewTransitionStyle.Fade
alertView.show()
}
