◆ webView:identifierForInitialRequest:fromDataSource:()
webView:identifierForInitialRequest:fromDataSource:
- Parameters
-
| sender | The WebView sending the message. |
| request | The request about to be sent. |
| dataSource | The datasource that initiated the load. An implementor of WebResourceLoadDelegate should provide an identifier that can be used to track the load of a single resource. This identifier will be passed as the first argument for all of the other WebResourceLoadDelegate methods. The identifier is useful to track changes to a resources request, which will be provided by one or more calls to resource:willSendRequest:redirectResponse:fromDataSource:. |
- Returns
- An identifier that will be passed back to the implementor for each callback. The identifier will be retained.

webView:plugInFailedWithError:dataSource: Called when a plug-in is not found, fails to load or is not available for some reason.
- Parameters
-
| sender | The WebView sending the message. |
| error | The plug-in error. In the userInfo dictionary of the error, the object for the NSErrorFailingURLKey key is a URL string of the SRC attribute, the object for the WebKitErrorPlugInNameKey key is a string of the plug-in's name, the object for the WebKitErrorPlugInPageURLStringKey key is a URL string of the PLUGINSPAGE attribute and the object for the WebKitErrorMIMETypeKey key is a string of the TYPE attribute. Some, none or all of the mentioned attributes can be present in the userInfo. The error returns nil for userInfo when none are present. |
| dataSource | The dataSource that contains the plug-in. |
◆ webView:resource:didCancelAuthenticationChallenge:fromDataSource:()

- Parameters
-
| sender | The WebView sending the message. |
| identifier | An identifier that can be used to track the progress of a resource load across multiple call backs. |
| error | The error associated with this load. |
| dataSource | The dataSource that initiated the load. |
◆ webView:resource:didFinishLoadingFromDataSource:()
| - (void WebResourceLoadDelegate) webView: |

|
optional |
webView:resource:didFinishLoadingFromDataSource: This message is sent after a load has successfully completed.
- Parameters
-
| sender | The WebView sending the message. |
| identifier | An identifier that can be used to track the progress of a resource load across multiple call backs. |
| dataSource | The dataSource that initiated the load. |
◆ webView:resource:didReceiveAuthenticationChallenge:fromDataSource:()
webView:resource:didReceiveAuthenticationChallenge:fromDataSource: Start authentication for the resource, providing a challenge Call useCredential::, continueWithoutCredential or cancel on the challenge when done.
- Parameters
-
| challenge | The NSURLAuthenticationChallenge to start authentication for If you do not implement this delegate method, WebKit will handle authentication automatically by prompting with a sheet on the window that the WebView is associated with. |
◆ webView:resource:didReceiveContentLength:fromDataSource:()
| - (void WebResourceLoadDelegate) webView: |
|
(WebView *) |
sender |
| resource: |
|
(id) |
identifier |
| didReceiveContentLength: |
|
(NSInteger) |
length |
| fromDataSource: |
|
(WebDataSource *) |
dataSource |
|
|
| |
|
optional |
webView:resource:didReceiveContentLength:fromDataSource: Multiple of these messages may be sent as data arrives.
- Parameters
-
| sender | The WebView sending the message. |
| identifier | An identifier that can be used to track the progress of a resource load across multiple call backs. |
| length | The amount of new data received. This is not the total amount, just the new amount received. |
| dataSource | The dataSource that initiated the load. |
◆ webView:resource:didReceiveResponse:fromDataSource:()
webView:resource:didReceiveResponse:fromDataSource: This message is sent after a response has been received for this load.
- Parameters
-
| sender | The WebView sending the message. |
| identifier | An identifier that can be used to track the progress of a resource load across multiple call backs. |
| response | The response for the request. |
| dataSource | The dataSource that initiated the load. In some rare cases, multiple responses may be received for a single load. This occurs with multipart/x-mixed-replace, or "server push". In this case, the client should assume that each new response resets progress so far for the resource back to 0, and should check the new response for the expected content length. |
◆ webView:resource:willSendRequest:redirectResponse:fromDataSource:()
webView:resource:willSendRequest:redirectResponse:fromDataSource: This message is sent before a load is initiated. The request may be modified as necessary by the receiver.
- Parameters
-
| sender | The WebView sending the message. |
| identifier | An identifier that can be used to track the progress of a resource load across multiple call backs. |
| request | The request about to be sent. |
| redirectResponse | If the request is being made in response to a redirect we received, the response that conveyed that redirect. |
| dataSource | The dataSource that initiated the load. |
- Returns
- Returns the request, which may be mutated by the implementor, although typically will be request.
