The C function is invoked sometimes and sometimes it does not. The sequence of code execution remains the same. It's not clear if this is a bug and, if it is, if it's related to the custom renderer in XF or Xamarin.

Please add a self-contained test case and include which versions of the product you used. The IOS version is Can you please elaborate on the self-contained test case. A self-contained test case is either a project on GitHub or in an attached zip cvs store that we can build and confirm with the above product that we get the same results.

The info is given below. I will ask my supervisor to upload the code on GitHub repository and share it on a public forum. Is there any way to share code privately. Can you provide any pointers. It's often simpler both for debugging and approval if you can remove as much code as possible from the application before zipping or creating a repo. We have not received the requested information.

Hit the button to invoke C function from JavaScript. AtDocumentEnd, false ; userController. AddUserScript script ; userController. RemoveAllUserScripts ; userController. ToString ; BluetoothManager.In our first two projects we used Interface Builder for a lot of layout work, but here our layout will be so simple that we can do the entire thing in code.

You see, before we were adding buttons and images to our view, but in this project the web view is going to take up all the space so it might as well be the view controller's main view.

So far, we've been using the viewDidLoad method to configure our view once its layout has loaded. This time we need to override the actual loading of the view because we don't want that empty thing on the storyboard, we want our own code. It will still be placed inside the navigation controller, but the rest is up to us.

When we create the web view, we need to store it as a property so we can reference it later on. So, add this property to the class now:. However, I encourage you to structure your methods in an organized way, and because loadView gets called before viewDidLoad it makes sense to position the code above it too. Anyway, there are only three things we care about, because by now you should understand why we need to use the override keyword.

Hint: it's because there's a default implementation, which is to load the layout from the storyboard. Third, we make our view the root view of the view controller that web view.

Yes, I missed out the second line, and that's because it introduces new concept: delegation. Delegation is what's called a programming pattern — a way of writing code — and it's used extensively in iOS. And for good reason: it's easy to understand, easy to use, and extremely flexible. A delegate is one thing acting in place of another, effectively answering questions and responding to events on its behalf.

But as smart as WKWebView is, it doesn't know or care how our application wants to behave, because that's our custom code. The delegation solution is brilliant: we can tell WKWebView that we want to be informed when something interesting happens.

Webview navigated event not called

In our code, we're setting the web view's navigationDelegate property to selfwhich means "when any web page navigation happens, please tell me — the current view controller.

When you set any delegate, you need to conform to the protocol that matches the delegate. Yes, all the navigationDelegate protocol methods are optional, but Swift doesn't know that yet. All it knows is that we're promising we're a suitable delegate for the web view, and yet haven't implemented the protocol.

The fix for this is simple, but I'm going to hijack it to introduce something else at the same time, because this is an opportune moment. First, the fix: find this line:. That's the fix. The order here really is important: the parent class superclass comes first, then all protocols implemented come next, all separated by commas.

We're saying that we conform to only one protocol here WKNavigationDelegate but you can specify as many as you need to. This program is almost doing something useful, so before you run it let's add three more lines. Please place these in the viewDidLoad method, just after the super call:.

I'm using hackingwithswift. Now, this probably seems like pointless obfuscation from Apple, but WKWebViews don't load websites from strings like www. Fortunately it's not hard to do!

Warning: Your URL must be complete, and valid, in order for this process to work. The third line enables a property on the web view that allows users to swipe from the left or right edge to move backward or forward in their web browsing. This is a feature from the Safari browser that many users rely on, so it's nice to keep it around.

Step one done!With Titanium SDK 8. WKWebView also has few restriction specially with local file accessing. To fix this, use the asynchronous solution:. This also ensures that your app does not receive unwanted messages by remote pages.

Note 1: Since 2. Instead, it returns the JavaScript evaluation result directly. While we understand there might be use-cases for this functionality, we highly recommend using asynchronous communication instead since synchronous method calls with block the user interface and may cause in an app-termination for long-running evaluations.

Note 2: Since 2. App-like events that allows the developer to fire events and add event-listeners to ease the communication between the app and the web-view.

These are:. The above events can be used on the JavaScript side as well. If you want to allow users to browse the internet e. Other URL schemes i. Use the configuration API to configure the initial web-view. This property can only be set when creating the webview and will be ignored when set afterwards.

Use process pools to share cookies between webviews. Process pools do not take arguments, just pass the same reference to multiple web views. WKWebView scaling. Blob, Ti.

The next thing we need to do is to set up communication between our web interface and the Sketch plugin. This message needs to tell us about what settings the user has input — like the number of steps, rotation amount, the number of duplicates to create, and so on.

Head over to our ui. Add the following at the top of the file:. The code we just added creates the native object we need.

It also defines a method on that object named userContentController:didReceiveScriptMessage: — this method is then called with the message we want as the second argument. Next, we need to add some code to our web interface to send us those messages. Here we use window. You should see an alert like the one below — this means everything is wired up correctly and our message went through successfully! If not, go back over the previous steps and ensure that everything was done as described.

Simplifying things a bit, what our code needs to do is:. The first two steps we need to take are getting the current document, and then its selected layer.

At the top of the file, add:. The Document object has a method specifically for accessing the current document we can use, called getSelectedDocument. It exposes the actual layer array via the layer property. We can once again use destructuring like we did earlier with Document to pull those properties out of options :. That way we can ensure that rotation and opacity will be applied to the template, but not spacing. Next, we need to create our duplicates. Since we already applied the starting options to the template layer, we need to take those options we just applied and add the relative values of stepOptions in order to get the options to apply to the next layer.

Once we have these options, we can then call the mosaic function with them. First, parsing. Finally, head over to main. By creating a Fiber, we tell Sketch that something asynchronous is happening and that it needs to keep our script around. Sketch will then only destroy our script when absolutely necessary like the user closing Sketch, or when the Mosaic plugin needs to be updated :.

With a layer selected in Sketch, enter some settings, then click apply:. To implement this, we have two problems to solve:.

Our original code follows the following steps:. To begin with, we need a means of identifying whether or not a group is one of the special groups belonging to us or not. Here, the Settings module of the Sketch library comes to our rescue. We can use it to store custom information on a particular layer, and also to read it back. After the code we already wrote to duplicate a layer, add:.With Titanium SDK 8.

Created by Brian Immel on Aug 14, WKWebView scaling. Blob, Ti.WKWebView runs out of process, meaning that its memory is threaded separately from the app; when it exceeds its allocation, it will crash without crashing the app which results in the app being notified and attempting to reload the page.

In contrast, UIWebView runs in process, which means that the memory it uses is considered to be part of the app's footprint and, if this exceeds what iOS wants to allocate, the app itself will be crashed by the operating system. While there is often a notification from iOS before this occurs that can allow us to avert a crash, this is sometimes either not returned quickly enough to act on or isn't returned at all. Communication between JavaScript and native code is handled asynchronously in WKWebView, which means that in general things execute more quickly.

In practice, this means that calls from our JavaScript API will not block the thread and callback functions must be used wherever a result has to be returned before the next step is completed. To successfully pull the device ID for use as the filename, this had to be restructured to use callbacks instead:. As a result, there's no way for us to increase the sensitivity or speed of a touch event. This delay is one of the most prominent reasons that HTML-based web apps are considered "sluggish" by many users.

In practical terms, this means that when using WKWebView, you can enter site credentials for password protected websites. While WKWebView was introduced in iOS 8, there are significant limitations in those versions, including the inability to access locally stored files, that we are unable to work around so this feature is not backwards-compatible.

Projects that use this type of request should either be hosted remotely on a server or use the existing UIWebView browsing engine.

While WKWebView does support the use of cookies, it does not expose the ability to select which cookies are accepted by source. Still stuck? How can we help? Handles JavaScript asynchronously Communication between JavaScript and native code is handled asynchronously in WKWebView, which means that in general things execute more quickly. Does not support 'Accept Cookies' setting While WKWebView does support the use of cookies, it does not expose the ability to select which cookies are accepted by source.

Last updated on September 20, Upload file.The reason for the Navigating and Navigated events, Is the WebView downloads the data so an event can be triggered when it's loaded, however with HTML it's local data passed in, no event will fire because it should be instant. Whether the moment it executes is when you want to be notified, or whether you want it to add an event handler to wait for something else depends on your precise requirements.

No this is not possible, because the Navigated event definition is "Event that is raised after navigation completes. You're setting a HtmlWebViewSource instead. Xamarin Inc.
