Question

Ok, I’m trying to get a file from my webserver. But I’m getting kinda confused about some stuff. When I use NSURL I can get my xml-file with an url like this: “localhost…../bla.xml”. But I’m also trying to test some things… Like… What will happen to my app if I have an open connection to the webserver, and I lose connection to internet? The above method with the NSURL, I haven’t really established any connection where it always is connected right? or should I use be using NSURLConnection?

Maybe it’s a little confusing, because I’m confused. I hope someone can give me some info I can research about.

Thanks.

Take a look at NSURLConnection Class.
http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSURLConnection_Class/Reference/Reference.html

Create connection object and set a timeout value, if you lose the connection or the connection times out NSURLConnection delegate method: - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error gets called and you would be notified of that event.

You might also use NSURLConnection sendSynchronousRequest method, but its strongly discouraged to use that method as it would block the thread its running.
