TBWKWebView is a WKWebView subclass which supports a completion block callback, enqueuing multiple URLRequest and executing them one by one. This is particularly useful for implementing crawler-like functionality from within an iOS app.
Copy TBWKWebView.swift to your project, or use the entire TBWKWebView.framework.
self.webView = TBWKWebView()
self.webView.enqueue(URLRequest(url: URL(string: "https://www.google.com")!)) { (navigation, error) in
// The webpage has either been fully loaded (didFinish)
// or has not been loaded at all (didFail, didFailProvisionalNavigation)
// Check error == nil and handle the rest
// Check self.webView.url and see if it has arrived at a page that you expected
// If you are done, return .complete to let the webView process the next enqueued URLRequest
return .complete
// If you are not yet done (e.g. you are waiting for the loaded JS to perform another navigation)
// you can return .incomplete and the webView will call the very same callback next time
// it encounter didFinish, didFail or didFailProvisionalNavigation delegate calls.
//return .incomplete
};
// You can enqueue multiple URLRequest - they will be sequentially loaded.
self.webView.enqueue(URLRequest(url: URL(string: "https://some.page.to.visit.after.visiting.google.com")!), completionHandler:nil)
Take a look at the unit tests as well.
