Terry, I considered using this control to solve a problem for a customer but have yet to work with this.  You have to consider that caveat with my comments.

I think the HTMLtext has to be a full page with <html> tag and everything.

That's what I was trying to load initially but when that didn't work I went with something simpler (didn't work either).

I have also heard that Apple is going with stricter standards compliance with iOS 5.0 or 5.1 (perhaps for security reasons) and what might work in some browsers might not work as HTMLtext.

I would think this should work with an empty baseURL, but you might want to try putting something in there.

If you have defined browserLoadRequest, you might need to pass that even for "load" (based on a comment I have seen online concerning the underlying method "loadHtmlString").  I'm not sure what the URL or type passed to browserLoadRequest would be for "load".

You might get some debug info by defining handlers for the messages sent by the control and seeing which if any are called for "load".  Log all parameters.  At minimum define browserLoadFailed.  (I don't really know if "load" will cause these to be sent, but I think so.)

I'll have a closer look at the messages - it seems to fail silently as no errors are thrown and the result stays empty.

You might be able to learn more from UIWebView documentation and even some examples.  Even if you are not familiar with Objective C, you might get a clue such as a test script that works.

Not many clues there - it seems you just pass some html and a base url as you do in the Livecode implementation.

Like I said, this is just what I learned in preparation for using this, and then I did not.

Thanks for your thoughts anyway Dar - for the moment I've gone with writing the html out to a local file first and loading that, which works fine. Still it would be easier if I could load it directly and the docs say I should be able to. Will play with it a bit more and then lodge a bug report if I still can't get it to work.

I'm passing empty as the baseURL (I'm not sure what this is for anyway) and have tried passing simple and complex chunks of html without success. Has anyone got this to work (Livecode 5.5)? The browser object seems to function fine otherwise as I can load a url in it no problems.

The baseURL is for handling relative URL and image references in the HTMLtext.

Now that you've explained it it makes perfect sense. That's one part of the puzzle solved - thanks!
