【问题描述】：
我有一个 WKWebView，它应该加载以下网址：
https://buchung.salonmeister.de/place/#offer-details-page?id=907599&venueId=301655
她是我使用的代码：
import UIKit
import WebKit
class MMWKBrowserController: UIViewController {
private let closeButtonSelector: Selector = "closeButtonTapped:"
private var urlString: String
private let request: NSMutableURLRequest
private var webView: WKWebView!
private var twoLineTitleView: UIView!
private var titleLabel: UILabel?
private var subTitleLabel: UILabel?
private var indicator: UIActivityIndicatorView!
init(urlString: String) {
self.urlString = urlString
println("*** Using MMWKBrowserController ***")
var url: NSURL? = NSURL(string: urlString)
if url == nil {
var escapedString: String = urlString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!
self.urlString = escapedString
url = NSURL(string: escapedString)
}
println("url: \(url)")
request = NSMutableURLRequest(URL: url!)
request.setValue("Mozilla/5.0 (iPhone; CPU iPhone OS 8_4 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Version/8.0 Mobile/12H141 Safari/600.1.4", forHTTPHeaderField: "UserAgent")
super.init(nibName: nil, bundle: nil)
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
deinit {
self.webView.removeObserver(self, forKeyPath: "loading")
self.webView.removeObserver(self, forKeyPath: "title")
self.webView.removeObserver(self, forKeyPath: "URL")
self.webView.removeObserver(self, forKeyPath: "estimatedProgress")
self.webView.stopLoading()
}
override func viewDidLoad() {
super.viewDidLoad()
createNavigationView()
self.navigationController?.navigationBar.tintColor = MGColor.actionColor
let config = WKWebViewConfiguration()
self.webView = WKWebView(frame: self.view.bounds, configuration: config)
self.view.addSubview(self.webView)
indicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)
//indicator.backgroundColor = UIColor(white: 0.1, alpha: 0.5)
webView.addSubview(indicator)
self.webView.snp_makeConstraints { (make) -> Void in
make.edges.equalTo(self.view)
}
indicator.snp_makeConstraints { (make) -> Void in
make.center.equalTo(self.webView)
}
webView.addObserver(self, forKeyPath: "loading", options: NSKeyValueObservingOptions.New, context: nil)
webView.addObserver(self, forKeyPath: "title", options: NSKeyValueObservingOptions.New, context: nil)
webView.addObserver(self, forKeyPath: "URL", options: NSKeyValueObservingOptions.New, context: nil)
webView.addObserver(self, forKeyPath: "estimatedProgress", options: NSKeyValueObservingOptions.New, context: nil)
}
override func viewDidDisappear(animated: Bool) {
super.viewDidDisappear(animated)
self.webView.stopLoading()
}
private func createNavigationView() {
let closeItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Stop, target: self, action: closeButtonSelector)
self.navigationItem.leftBarButtonItem = closeItem
// create center view
let titleViewWidth = self.view.frame.size.width - 100
twoLineTitleView = UIView(frame: CGRectMake(0, 0, titleViewWidth, 44))
titleLabel = UILabel(frame: CGRectMake(0, 6, titleViewWidth, 16))
titleLabel?.backgroundColor = UIColor.clearColor()
titleLabel?.font = UIFont.boldSystemFontOfSize(16)
titleLabel?.textAlignment = NSTextAlignment.Center
subTitleLabel = UILabel(frame: CGRectMake(0, 21, titleViewWidth, 20))
subTitleLabel?.backgroundColor = UIColor.clearColor()
subTitleLabel?.font = UIFont.systemFontOfSize(10)
subTitleLabel?.textAlignment = NSTextAlignment.Center
twoLineTitleView.addSubview(titleLabel!)
twoLineTitleView.addSubview(subTitleLabel!)
self.navigationItem.titleView = twoLineTitleView
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.webView.loadRequest(self.request)
}
func closeButtonTapped(sender: UIBarButtonItem) {
self.presentingViewController?.dismissViewControllerAnimated(true, completion: nil)
}
override func observeValueForKeyPath(keyPath: String, ofObject object: AnyObject, change: [NSObject : AnyObject], context: UnsafeMutablePointer<Void>) {
if let wk = object as? WKWebView {
switch keyPath {
case "loading":
if let val: AnyObject = change[NSKeyValueChangeNewKey] {
if let val = val as? Bool {
if val {
self.indicator.startAnimating()
}
else {
self.indicator.stopAnimating()
}
}
}
case "title":
self.titleLabel?.text = self.webView.title
case "URL":
self.subTitleLabel?.text = self.webView.URL?.URLString
case "estimatedProgress":
println("progress: \(Int32(self.webView.estimatedProgress*100))")
default: break
}
}
}
}
注意：我使用 SDK iOS 8.4
为什么移动版 Safari 会加载此网址，而 WKWebView 却没有？
【问题讨论】：
-
您使用的是哪个 SDK？ iOS8 还是 iOS 9？
-
这部分 url 加载正常：buchung.salonmeister.de，其余部分可能包含一些 webview 工具包无法识别的字符。尝试不同的选择。
-
我添加了
webView.loadRequest(request)（参见screenshot）后，您的 webView 对我有效，但请注意，您的 URL 似乎指向的页面不再存在。 -
在移动 Safari 中加载 URL，您会看到页面加载。
-
您可能需要将
www添加到您的字符串中，苹果似乎对其格式非常挑剔。
