Provided Methods§

Source

unsafe fn webView_decidePolicyForNavigationAction_decisionHandler( &self, web_view: &WKWebView, navigation_action: &WKNavigationAction, decision_handler: &Block<dyn Fn(WKNavigationActionPolicy)>, )
where Self: Sized + Message,

Available on crate feature WKNavigationAction and crate feature WKWebView and crate feature block2 and crate feature objc2-app-kit and macOS only.

Decides whether to allow or cancel a navigation.

Parameter webView: The web view invoking the delegate method.

Parameter navigationAction: Descriptive information about the action triggering the navigation request.

Parameter decisionHandler: The decision handler to call to allow or cancel the navigation. The argument is one of the constants of the enumerated type WKNavigationActionPolicy.

If you do not implement this method, the web view will load the request or, if appropriate, forward it to another application.

Source

unsafe fn webView_decidePolicyForNavigationAction_preferences_decisionHandler( &self, web_view: &WKWebView, navigation_action: &WKNavigationAction, preferences: &WKWebpagePreferences, decision_handler: &Block<dyn Fn(WKNavigationActionPolicy, NonNull<WKWebpagePreferences>)>, )
where Self: Sized + Message,

Available on crate feature WKNavigationAction and crate feature WKWebView and crate feature WKWebpagePreferences and crate feature block2 and crate feature objc2-app-kit and macOS only.

Decides whether to allow or cancel a navigation.

Parameter webView: The web view invoking the delegate method.

Parameter navigationAction: Descriptive information about the action triggering the navigation request.

Parameter preferences: The default set of webpage preferences. This may be changed by setting defaultWebpagePreferences on WKWebViewConfiguration.

Parameter decisionHandler: The policy decision handler to call to allow or cancel the navigation. The arguments are one of the constants of the enumerated type WKNavigationActionPolicy, as well as an instance of WKWebpagePreferences.

If you implement this method, -webView:decidePolicyForNavigationAction:decisionHandler: will not be called.

Source

unsafe fn webView_decidePolicyForNavigationResponse_decisionHandler( &self, web_view: &WKWebView, navigation_response: &WKNavigationResponse, decision_handler: &Block<dyn Fn(WKNavigationResponsePolicy)>, )
where Self: Sized + Message,

Available on crate feature WKNavigationResponse and crate feature WKWebView and crate feature block2 and crate feature objc2-app-kit and macOS only.

Decides whether to allow or cancel a navigation after its response is known.

Parameter webView: The web view invoking the delegate method.

Parameter navigationResponse: Descriptive information about the navigation response.

Parameter decisionHandler: The decision handler to call to allow or cancel the navigation. The argument is one of the constants of the enumerated type WKNavigationResponsePolicy.

If you do not implement this method, the web view will allow the response, if the web view can show it.

Source

unsafe fn webView_didStartProvisionalNavigation( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when a main frame navigation starts.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Source

unsafe fn webView_didReceiveServerRedirectForProvisionalNavigation( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when a server redirect is received for the main frame.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Source

unsafe fn webView_didFailProvisionalNavigation_withError( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, error: &NSError, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when an error occurs while starting to load data for the main frame.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Parameter error: The error that occurred.

Source

unsafe fn webView_didCommitNavigation( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when content starts arriving for the main frame.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Source

unsafe fn webView_didFinishNavigation( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when a main frame navigation completes.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Source

unsafe fn webView_didFailNavigation_withError( &self, web_view: &WKWebView, navigation: Option<&WKNavigation>, error: &NSError, )
where Self: Sized + Message,

Available on crate feature WKNavigation and crate feature WKWebView and crate feature objc2-app-kit and macOS only.

Invoked when an error occurs during a committed main frame navigation.

Parameter webView: The web view invoking the delegate method.

Parameter navigation: The navigation.

Parameter error: The error that occurred.

Source

unsafe fn webView_didReceiveAuthenticationChallenge_completionHandler( &self, web_view: &WKWebView, challenge: &NSURLAuthenticationChallenge, completion_handler: &Block<dyn Fn(NSURLSessionAuthChallengeDisposition, *mut NSURLCredential)>, )

Available on crate feature WKWebView and crate feature block2 and crate feature objc2-app-kit and macOS only.

Invoked when the web view needs to respond to an authentication challenge.

Parameter webView: The web view that received the authentication challenge.

Parameter challenge: The authentication challenge.

Parameter completionHandler: The completion handler you must invoke to respond to the challenge. The disposition argument is one of the constants of the enumerated type NSURLSessionAuthChallengeDisposition. When disposition is NSURLSessionAuthChallengeUseCredential, the credential argument is the credential to use, or nil to indicate continuing without a credential.

If you do not implement this method, the web view will respond to the authentication challenge with the NSURLSessionAuthChallengeRejectProtectionSpace disposition.
