I'm working with a WebView. If I place this call in my -awakeFromNib:
[myWebView setMainFrameURL:#"http://www.google.com"];
I get the behavior I want. Google's homepage displays in my WebView. But, I need to set the main frame's URL in another method from a mutable array containing NSStrings.
This method call
[myWebView setMainFrameURL:[mutableArrayContainingNSStrings objectAtIndex:0]];
does not update the WebView. Do I need to tell the WebView to reload? I tried -setNeedsDisplay:YES and -reload to no avail.
I figured out the problem. The WebView is an IBOutlet. I was doing the method call that was giving me problems before -awakeFromNib. Moved that one line to -awakeFromNib and it's sorted now. Thanks for the input. +1 to my list of newbie posts.
Have you tried setting a breakpoint on your action method to check that both myWebView and [mutableArrayContainingNSStrings objectAtIndex:0] are pointing to the correct objects?
Several things
(1) I second Marc's comment in making sure that it is pointing at the correct objects
(2) It's been a while since I've dealt with WebKit directly but I know that it's possible you may have strings like "www.google.com" and strings like that won't work, you need "http://www.google.com" which you have in your first call to myWebView. Make sure all of your URL Strings are like this. It's the browser (Safari/Chrome/etc) that expands www.google.com out into http://www.google.com so that you can actually visit the site
If none of that works show the strings here so I can verify and run tests to see what's going on with the WebView

I'm trying to make an Apple Help book for my macOS app that I'm ready to release. However, I am trying to make anchors work in my HTML. By Apple's definition:
"Anchors allow you to uniquely identify topics in your help book. When
a user follows a link to an anchor, Help Viewer loads the page
containing the anchor. ... You can also use anchors to load an
anchored page from within your application by calling the the
NSHelpManager method openHelpAnchor:inBook: ..."
Example from Apple: <a name="ArrivalTimesUsingStopID"></a>
In my Apple, I have an NSAlert which has the following code to display the help button so that when you click on it, it opens the specified anchor string.
alert.showsHelp = true
alert.helpAnchor = NSHelpManager.AnchorName(stringLiteral: "ArrivalTimesUsingStopID")
Running the code does display the help button and Mac Help does open, but to an error saying that the specified content cannot be found. Not sure why the anchors aren't working because I can access the Help Book if I go to the Help menu and open it from there.
Furthermore, Apple's document states:
The NSAlert, SFChooseIdentityPanel, SFCertificatePanel classes provide
help buttons for dialogs. To display such a help button and link it to
an anchor in your help book, use the methods setShowsHelp: and
setHelpAnchor: in those classes.
and the documentation for these properties in NSAlert state:
-setShowsHelp:YES adds a help button to the alert panel. When the help button is pressed, the delegate is first consulted. If the delegate
does not implement alertShowHelp: or returns NO, then -[NSHelpManager
openHelpAnchor:inBook:] is called with a nil book and the anchor
specified by -setHelpAnchor:, if any. An exception will be raised if
the delegate returns NO and there is no help anchor set.
...so I know that I am using these two properly.
I also understand that I need to create a .helpindex file every time I update my Apple Help book HTML documents. I'm using "Help Indexer.app" which is in the Additional Xcode Tools on developer.apple.com. I make sure that:
I have the option set to index all anchors.
Any HTML page with an anchor has <meta name="ROBOTS" content="ANCHORS"> in the header so anchors are indexed.
My Apple Help book plist file correctly points to the .helpindex file created by "Help Indexer.app".
But even with all of this, I cannot get it to open the Apple Help book to the correct anchor or even the Title page of my Apple Help book.
I've read
https://developer.apple.com/library/archive/documentation/Carbon/Conceptual/ProvidingUserAssitAppleHelp/user_help_intro/user_assistance_intro.html#//apple_ref/doc/uid/TP30000903-CH204-CHDIDJFE
from cover to cover multiple times and I cannot find a solution or anywhere online.
I've also tried opening it manually, but it just opens to the same error saying the specified content couldn't be found with the following code:
let bookName = Bundle.main.object(forInfoDictionaryKey: "CFBundleHelpBookName") as! String
NSHelpManager.shared.openHelpAnchor("ArrivalTimesUsingStopID", inBook: bookName)
Using nil for the inBook parameter doesn't work either:
NSHelpManager.shared.openHelpAnchor("ArrivalTimesUsingStopID", inBook: nil)
Any ideas?
I'm not sure if this is the answer at this point, but it is an answer and one that seems to do the trick. I wasn't able to get the helpAnchor in the Alert to work, but using the help delegate, the method outlined below works.
I started out my day trying to open the Help Book to a simple anchor. I'm sure this used to work using the NSHelpManager in the past, but it does not appear to in recent versions of the OS.
Watching the console while opening my under-development App's help book resulted in the following:
Opening URL help:openbook=%22com.ClueTrust.Cartographica.help*1.5.2d1%22 with application <FSNode 0x6000006a1b40> { isDir = y, path = '/System/Library/CoreServices/HelpViewer.app' }
Opening to my anchor using NSHelpManager resulted in:
Opening URL help:anchor=SpatialJoinOperation%20bookID=%22com.ClueTrust.Cartographica.help%22%20appID=%22com.ClueTrust.Cartographica%22 with application <FSNode 0x6000006a8260> { isDir = y, path = '/System/Library/CoreServices/HelpViewer.app' }
And, it didn't result in opening to my anchor.
I tried appending the *<version> to my URL:
Opening URL help:anchor=SpatialJoinOperation%20bookID=%22com.ClueTrust.Cartographica.help*1.5.2d1%22%20appID=%22com.ClueTrust.Cartographica%22 with application <FSNode 0x600000682c20> { isDir = y, path = '/System/Library/CoreServices/HelpViewer.app'
Looking deeper into the Console, though, I noticed that this is definitely triggering a network request and there's an unsupported URL coming back.
It's not clear to me if help:anchor=... does not function any longer, but I did find a relatively easy, but annoying way around the problem.
Anchors within help will definitely be opened when using a help: URL that is formatted like a file: URL and contains an anchor; and they will open to the correct anchor location.
This requires locating the specific help book and HTML file so that you can specify precisely where to open.
NSURL *helpBookURL = [NSBundle.mainBundle URLForResource:#"Cartographica" withExtension:#"help"];
NSBundle *helpBundle = [NSBundle bundleWithURL:helpBookURL];
NSURL *helpPageURL = [helpBundle URLForResource:#"Spatial_Join" withExtension:#"html"];
NSURLComponents *urlParts = [NSURLComponents componentsWithURL:helpPageURL resolvingAgainstBaseURL:NO];
urlParts.scheme=#"help";
urlParts.fragment=#"SpatialJoinOperation";
NSURL *finalHelpURL = urlParts.URL;
[NSWorkspace.sharedWorkspace openURL:finalHelpURL];
Basically:
Get the URL for the help book (need to do this in a way that gets it from the resource path, hence we're using NSBundle)
Locate the page containing the reference based on prior knowledge (in this case Spatial_Join.html is our filename, so we have the bundle look for it by name and extension.
Use the NSURLComponents interface to mutate the NSURL by changing the scheme from file to help and adding our achor in the fragment.
Finally, open the newly-created URL
It's not pretty, but it does appear to be effective and safe, at least in a non-sandboxed macOS App under 10.15.
Note that I could make some assumptions here about the help book name, but for illustration purposes this seems more clear, and because of the way resources work, it's not clear that those assumptions about the names would be appropriate in all situations.
My final result was this helper method:
- (void)openHelpPage:(NSString*)pageName anchor:(NSString * _Nullable)anchor bookName:(NSString * _Nullable)bookName
{
NSURL *helpBookURL = [NSBundle.mainBundle URLForResource:bookName withExtension:#"help"];
NSBundle *helpBundle = [NSBundle bundleWithURL:helpBookURL];
NSURL *helpPageURL = [helpBundle URLForResource:pageName withExtension:#"html"];
NSURLComponents *urlParts = [NSURLComponents componentsWithURL:helpPageURL resolvingAgainstBaseURL:NO];
urlParts.scheme=#"help";
if (anchor)
urlParts.fragment=anchor;
NSURL *finalHelpURL = urlParts.URL;
[NSWorkspace.sharedWorkspace openURL:finalHelpURL];
}
Call site syntax is:
// to specific anchor on a page
[self openHelpPage: #"Spatial_Join" anchor: #"SpatialJoinOperation" helpBook: nil];
// to specific page
[self openHelpPage: #"Spatial_Join" anchor: nil helpBook: nil];
I tried getting the help bundle with [NSBundle bundleWithIdentifier:] using the help bundle ID, but that returned nil. However, [NSBundle URLForResource:withExtension] will take a nil argument for the resourceName and get the first item that matches the extension. In my case (and I believe many) there is only one help resource, so this allows for a method that doesn't require knowledge of the Application's help book name.
I was finally able to get this working in a sandboxed application.
If you're using a Help button directly, you can use something like:
#IBAction func helpButtonAction(_ sender: Any)
{
if let bookName = Bundle.main.object(forInfoDictionaryKey: "CFBundleHelpBookName") as? String {
NSHelpManager.shared.openHelpAnchor("MY_ANCHOR_HERE", inBook: bookName)
}
}
If you're using an NSAlert(), you can use its help button with an anchor this way:
let alert = NSAlert()
...
alert.showsHelp = true
alert.helpAnchor = NSHelpManager.AnchorName("MY_ANCHOR_HERE")
A few things I learned the hard way:
Make sure your HTML page for your Help Book has a the proper setup for an anchor with:
<meta name="robots" content="anchors"> in the <head> section as well as a proper header tag in the fashion of:
<a name="MY_ANCHOR_HERE"></a> in your <body> section.
Make sure you use "Help Indexer.app" to index your Help Book. I found that it will not work unless you index your Help Book using this app. This app can be downloaded from developer.apple.com under More Downloads. They usually release a new version with every Xcode update. You want to look for "Additional Tools" and the specific indexer app will be located in
Additional Tools > Utilities > Help Indexer.app
Additionally, macOS does not like when you have multiple Help Books. This means, multiple copies of your Application on your Mac no matter where they reside. This could be in your Debug folder and your Application folder as your most common places. I found that deleting the copy in my Applications folder usually helps macOS not get confused when opening a Help Book. I have also found it to open up older versions of the Help Book so it's best to make sure you only have once copy of your app on your Mac when debugging help books.
But other than that, they should open just fine with simply an Anchor string and a few lines of code depending on how you display your Help button!
I am using ruby and capybara(which leverages selenium) to automate walking through a website. After navigating to a new page I verify that the new page URL is what i'm expecting. My issue comes when I walk through an order funnel that is a single page but loads different views.
Some code...
I create my session instance then have additional code opening the browser and walking to a certain point in the website that I wont include
$session = Capybara::Session.new(:selenium)
My line for checking the browser URL without search params ie: everything after '?'
if url == $session.current_url.to_s.split("?")[0]
urlCorrect = true
end
This code works fine when my URL is
https://www.homepage.com
Then I click on a link that takes me to my order funnel ... https://www.homepage.com/order#/orderpage1?option1=something&option2=somethingelse
My function still matches the expected URL. But the issue comes when I move to the second page of the order funnel :
https://www.homepage.com/order#/orderpage2?option1=something&option2=somethingelse
My capybara code to get current url still returns the URL from orderpage1. Im guessing its because there is no postback when moving from orderpage1 to orderpage2 but i dont know how to force a postback or tell capybara to re-grab the url
Any advice will be appreciated.
Thanks
Quick Edit: I forgot to mention this behavior is only in IE. Chrome and Firefox both work correctly with the exact same code
Capybara grabs the current_url by querying the browser - it doesn't cache it. The issue you're probably running into is that clicking the link to move to the next page doesn't wait for the page change to happen, so if you call current_url before the page load has happened you'll still get the original url. There are two solutions for that - 1. use capybara to look for content that doesn't appear until the new page is loaded ( have_content ), 2. use the has_current_path? method which will wait/retry for a period of time until the current_path/url match
$session.has_current_path?('expected path')
There are options if you want to match against the full url, and you can use a regex to match as well - http://www.rubydoc.info/gems/capybara/Capybara/SessionMatchers#has_current_path%3F-instance_method
Thanks to Tom Walpole for finding the bug report for this issue. This link sums up the root of the issue and provides a few workarounds if anyone else is encountering this issue.

From a view, is it possible to know which action led to the displaying of that view or if not, how do I get the last part of the path of the url (which will be the action name)?
Try this:
#ViewContext.Controller.ValueProvider.GetValue("action").RawValue
You can also get this from #Url.RequestContext.RouteData object:
#Url.RequestContext.RouteData.Values["action"]
Today I'm working with an interesting problem. I'm trying to code simple bookmarks, and by that I mean the most basic functionality; store the url, and load the url when you tap it.
Right now, the idea is that I would use the following:
currentURL = currentWebView.request.URL.absoluteString;
To retrieve the current URL, and then possibly store that within NSDefaults.
(Open to any other suggestions on better ways of preforming this)
However, the problem that I'm having is that, assuming I've gotten that far (retrieved the URL and stored it), how would I go about putting then somewhere in a list format that displays the url that was bookmarked, and then loading them (from that separate bookmarks view) in the main view that the UIWebView is contained in?
Your time is much appreciated

NOTE: If you need more information or anything I could possibly help you with in order to come to a solution, just ask
Simple
Suppose your viewcontroller where your webview resides, is WebViewController and where list shows is BookmarkViewController.
Create a property in BookmarkViewController
#property(nonatomic,retain)WebViewController *maincontroller;
Send the reference of your WebViewController to BookmarkViewController when you create BookmarkViewController object
bookmarkobject.maincontroller=self;
and then In didSelectRowAtIndexPath
either use
1) [maincontroller.webView loadRequest:url];
or
make a method in WebViewController with parameter url and call this method from didSelectRowAtIndexPath
2) [maincontroller loadUrlInWebView:url];
and dismiss your modal
or create a property of url in WebViewController and in didSelectRowAtIndexPath
3) [maincontroller urlstring:url];
and in viewWillAppear load this url in your webview
Hope any of these 3 methods will help you.
I put a Ajax link using the following code:
echo chtml::ajaxLink('GO', 'http://localhost/index.php?r=user/delete', array('method'=>'POST'));
But, regardless of giving the second parameter as URL i,e 'http://localhost/index.php?r=user/delete'. It generates link with the current URL in the browser not the URL I just specified.
What is the issue? How could I create AJAX link? Google several hours but can't solve the issue.
Any kind of help is highly appreciated.
First of all, you should always try and create normalized urls.
But i think your doubt lies in the # that is generated/appended. If you go and check the source of yii ajaxLink you'll see this:
public static function ajaxLink($text,$url,$ajaxOptions=array(),$htmlOptions=array())
{
if(!isset($htmlOptions['href']))
$htmlOptions['href']='#';
$ajaxOptions['url']=$url;
$htmlOptions['ajax']=$ajaxOptions;
self::clientChange('click',$htmlOptions);
return self::tag('a',$htmlOptions,$text);
}
so if you don't set the href property of the a tag in the htmloptions array, the # will be appended.
You should also understand that yii uses jquery, so if you check out the source of the page, you'll see at the bottom, how jquery is used to carry out an ajax request, your actual url that is called will also be seen in that script. So the third option/parameter in ajaxLink is for options for jquery's ajax function. You can create better ajax links using this option.
Regardless of where(which controller) your url points to in your project, the action associated with that url will be called.
So anyway, you can modify your code like this if you want the url to be shown and not a # :
echo CHtml::ajaxLink('GO', 'http://localhost/index.php?r=user/delete',
array('type'=>POST), //there are various other options for jquery ajax
array('href'=>'http://localhost/index.php?r=user/delete'));
To make better ajax links i would suggest going through jquery's ajax documentation. There is an option for a success function, that you can use to let the user know that the operation was completed.
Hope this helps, don't hesitate to leave comments if i haven't answered your question completely.
Have you tried:
echo CHtml::ajaxLink('GO', array('/user/delete'), array('method'=>'POST'));
as the ajaxLink documentation suggests...? Look also at the normalizeUrl method.
Using these methods, which in turn are using createUrl, is usually better since it will take care to create a valid url for your site.
I had the same issue(or maybe similar).
I've used renderPartial to load view and later in that view i was using ajaxLink and it was not working.
What i have found, that when using renderPartial, there was no jquery script for ajax action.
What you have to do is to add 4th argument(true) in renderPartial function to generate jquery script.
See the documentation: http://www.yiiframework.com/doc/api/1.1/CController/#renderPartial-detail
Hope it helps and saves time to figure it out.
