Invalid NSUrl

[Shades of Chaos]

Hey all,

I have an NSUrl that leads to a HTML file on the internet and I need this to be changeable. I have got the url changing but if the user enters an invalid url I want to know about it. Is there a way to check is the url is valid?

Thanks

You could use the NSData method dataWithContentsOfURLptions:error:

That's synchronous, however.

Looking at the docs, NSURLConnection has a method canHandleRequest that lets you preflight a connection before you try to start it. I haven't used it however.

Hey Duncan thanks for the quick reply. But apparently the validity of the url wasn't the problem. I am going to re-post with the new problem.

Thanks
