Loading webpage into UIwebview but images from local

votes

I have web page having 1000's of images and values. Whenever I load the page to UIWebView it gets loaded with values but as there are so many images it takes time to download.

So is there any way, I can download the page from web but images from local.

Any help is really appreciated.

Thank you,

Ankita

If you have your HTML from webserver and images at local

  1. yourBaseURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] bundlePath]];

  2. [webView loadHTMLString:@"YourHTML" baseURL:yourBaseURL]

and your HTML contains name of local image stored like

Image Tag like --> imgage src='fig1.jpg width=150 height=150 align="left"

Than this should work.

Not exactly as you required though this way you can load local images in webView.

Basically:

Download HTML from server.

NSURL *URL = [[NSURL alloc] initWithString:@"http://www.example.com/page.php"];
NSError *error = nil;
NSStringEncoding encoding;
NSString *theSource = [[NSString alloc] initWithContentsOfURL:URL usedEncoding:&encoding error:&error];

Replace the file references to load images locally.
Note the double slashes, this seems important.

// Replace:
<img src="File.png">
// By something like:
<img src="file://Path//To//Resources//File.png">

Detailed information how to do this (check post by Joe D'Andrea):

Finally make the UIWebView load the HTML:

[webView loadHTMLString:htmlString baseURL:baseURL];

Now it should load the 'fresh' HTML from the server with local images.

This works quite well for me.

NSURL *myBaseURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] bundlePath]];
NSString *myString = [[managedObject valueForKey:@"long_presentation"] stringByReplacingOccurrencesOfString:@"/FooFolder/BarFolder" withString:[NSString stringWithFormat:@"%@/FooFolder/BarFolder", [[NSBundle mainBundle] bundlePath] ] ];
[attractionWebView loadHTMLString:myString baseURL:myBaseURL];

I had to include a replacement for the image source

img src="FooFolder/BarFolder/my_image.jpg" ...

to get the right path.
