    I'm able to successfully load a local html-file into a UIWebView, and from that load a local image via the html-code.

    Loading a local sound-file from the UIWebView, however, is a different matter.

    Does anybody know why the code below only manages to display a local image but no local sound, and what the solution would be?


    Code:
    // 1) Get: Get string from “outline.plist” in the “DrillDownSave”-codesample.
savedUrlString = [item objectForKey: @"itemUrl"];

// 2) Set: The url in string-format, excluding the html-appendix.
NSString *tempUrlString = savedUrlString;

// 3) Set: Format a url-string correctly. The html-file is located locally.
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:tempUrlString ofType:@”html”];

// 4) Set: Set an “NSData”-object of the url-sting.
NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile];

// 5. Gets the path to the main bundle root folder
NSString *imagePath = [[NSBundle mainBundle] resourcePath];

// 6. Need to be double-slashes to work correctly with UIWebView, so change all “/” to “//”
imagePath = [imagePath stringByReplacingOccurrencesOfString:@"/" withString:@"//"];

// 7. Also need to replace all spaces with “%20″
imagePath = [imagePath stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

//  Load:	Loads the local html-page.
[webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:[NSString stringWithFormat:@"file:/%@//",imagePath]]];

    And here is the simple html-fil loaded into the UIWebView (not only the "img src" finds the local image, whereas the "embed src" does not find the local sound-file):

    Code:
    <HTML>
<BODY>
<img src=”logo.jpg”>
<br>
<embed src=”test.wav”>
</BODY>
</HTML>

    The iPhone's WebView cannot play html embedded sound.

    Hi Niiro13, and thanks for the input.

    Actually the embedded sound works fine as long as the sound-file is not loaded locally. Ie. this works:

    <embed src=”http://www.mysite.com/test.wav”>

    So the problem must be that the code doesn't find the local sound-file, not that WebView doesn't play embedded sounds, right?

    Hi,

    Did you try base64 encoding ?

    You could always try aiming the .wav file URL at localhost, and building a mini web server into your app. The mini web server wouldn't have to be fancy. It could just respond to any request by shipping the sound file.
