UIAlertControllerWrapperはUIAlertControllerをラップしたクラスです。
こちらを参考に作りました。
MyWebView.m
- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(nonnull NSURLAuthenticationChallenge *)challenge completionHandler:(nonnull void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler {
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic] == YES){
NSLog(@"didReceiveAuthenticationChallenge");
[UIAlertControllerWrapper showAlertViewWithIdAndPassword:@"Authentication" message:@"Input username and password." ok:^(UIAlertAction *action, UIAlertController *cntr){
NSURLCredential *credential = [NSURLCredential credentialWithUser:[cntr.textFields objectAtIndex:0].text password:[cntr.textFields objectAtIndex:1].text persistence:NSURLCredentialPersistenceForSession];
completionHandler(NSURLSessionAuthChallengeUseCredential, credential);
}cancel:^(UIAlertAction *cancel){
completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);
}];
}else{
completionHandler(NSURLSessionAuthChallengeRejectProtectionSpace, nil);
}
}
Javascript実行
MyWebView.m
[webView evaluateJavaScript:@"document.title"
completionHandler:^(NSString *result, NSError *error){
}];
