Image with data uri src not loading in UIWebView

Question

I have a simple image populated from a data uri that loads fine in MobileSafari, but when I load the same webpage in a UIWebView, it shows as a broken image:

I have no idea why. Is there some magic configuration of the UIWebView that I've forgotten?

Edit:

In Safari Web Inspector pointing to the UIWebView, I notice that it is interpreting the data uri as application/json, whereas if I load the file from the same server in MobileSafari, web inspector correctly recognizes it as image/jpeg.

Answer 1

I ended up working around the issue by embedding the file in my app bundle, and setting the base URL of my webview to the parent of that file:

    [webView loadHTMLString:html 
             baseURL:[[[NSBundle mainBundle] URLForResource:@"myimage" 
             withExtension:@"png"] URLByDeletingLastPathComponent ]];

Answer 2

I copied your image src data uri and created a simple html file and loaded it in uiwebview.It was working fine and I did not see any problem in loading your jpeg image file using a local html file. Please see the html file created below.
