Hi
I have a portion of code that uses NSURL to get a HTML file, e.g.
data = [NSMutableString stringWithContentsOfURL:[NSURL
URLWithString:@"http://www.apple.com/";]];
where data is, sensibly enough, a NSMutableString.
However, this approach produces the spinning beach ball mouse cursor
and the app seems to freeze up while retrieving the data. Is there a
way to work around this freeze?
Thanks

Put the fetch in a different thread (see NSThread).
Then have that thread call the action methods when it's done.

Hope that helped.
Instead of using an NSThread, I suggest creating an NSURL and using
loadResourceDataNotifyingClient: usingCache:. It will be much simpler
to implement.
