I'm working on a Iphone app that needs to open remote html files and use local images.I found this answer and it's the perfect solution for me :

but the problem is that this solution loads only the first image when I'm trying to load more images, like so :

The page will display the first image right but the other images will display the source of the first.

Set the src attribute of the webview to a data URL that has a reference to a local resource (e.g. Image tag) open the app and listen to the console-message event on the webview => Not allowed to load local resource: file:///C://1.jpg; It would be nice if for a webview you could bypass this security measure when you set a data URL. I load a local html file (from assets folder) to the app WebView. In the HTML I run a jQuery.getJSON(url). The url is a remote server. This action fails, and I’m guessing because of a different origin issue (cross domain).

Why are you using custom protocol implementations for loading local images in a html file ?

1. Before the example React Native Load Local HTML File in WebView, we are hoping you have visited our Webview Example in which we have loaded the HTML page from URL. Here is the example of how to show webpage from the locally available HTML file.
2. Override a remote HTML with a local Javascript file in UiWebView? Ask Question. We plan to load an external blank HTML file (served from Drupal) from our server through the UIWebView and would like the CSS and Javascript to be loaded from the local device. Website sends bare-bone non-styled HTML and the app loads the local CSS and JS to.

You can easily set the root of the html to the following :

This will load all image files from your bundle.

Or, you can override the load call, with a webview delegate like so :

And there completely customize how and where files should be loaded.

you can use the same idea in iOS WebView remote html with local image filesbut, use different custom protocol name for each imageFor example

Then ask which protocol name used in the canInitWithRequest method, then you can know which image you will load in startLoading method.

Note : canInitWithRequest is a class method therefore you can declare a static variable to hold the image file name in canInitWithRequest method

WKWebView doesn't allow files to be accessed from file storage(Document directory) directly, to access file from document directory you have to use loadFileURL:allowingReadAccessToURL: method, below is my code.

In ViewDidLoad

Above code saves an image from bundle to document directory, also it saves an html file(which will use img tag to load image).

Javascript Local File Path

Below didFinishNavigation:

Utility Method to get file url

and last the HTML file which has methods to get path from webview and load image

Above method is only way I found to load image/files from document directory.

You can also send your image/file in form of data url and pass it to the javascript method(already written in html file), just convert your image to NSData and base encode to string, javascript will convert the data url to image object itself.

I need to load javascript files from my apps resources folder. As of right now, it does read images from the resources just fine, but it's not reading javascripts for some reason.

I have been able to render html docs that reference these javascripts if the html files themselves are written into the resources, but I would like to render html/js by setting the html of a UIWebView so it can be dynamic.

Here is what I am doing:

Now, if I change the base url to my server which also has the required files, it does load correctly. It would be great to not require an internet connection. Any help is appreciated!!! ;)

I found this useful in getting images to display: iPhone Dev: UIWebView baseUrl to resources in Documents folder not App bundle

Edit:

Instead of doing the string replacing and URL encoding, I was able to get images to by simply calling resourceURL on the mainBundle, but still no javascript execution.

EDIT

If you want to help give this a shot, I have made it easier for you by creating an example project!

Here we go with a simple setup.

Create the following folder structure in your Resources folder.

Note that the blue folders are referenced ones

The css is just candy :) In lib.js resides your javascript code which you'd like to use.

index.html

lib.js

Loading of the content in the webview

Note: webView is a property, view created with instance builder

And this should be the results:

EDIT:

snowman4415 mentioned that iOS 7 does not like self closing tags script tags, so if something is not working on iOS 7, you may need to close the tag with </script>

Here is another way to inject a local javascript file into the DOM of a web view. You load the contents of the JS file into a string and then use stringByEvalutatingJavaScriptFromString:

This is especially useful when you don't own the *.html/xhtml files you are displaying (i.e. ePub reader. or news aggregator). It helps so that you don't have to worry about the relative paths from your xhtml file to your js file.
