dictionaryWithContentsOfURL Questons
-
Hello all. I am using dictionaryWithContentsOfURL to
check for new versions of a program i am working on,
the problem i am having is that if the user does not
have an internet connection the check will hang
forever (or atleast a long period of time). Is there
an easy way to set a timeout for this function? Thank
you for your time as always.

The best thing would be to do this in a thread. Here is the code that
our apps use for this purpose. This normally times out after ten
seconds in my experience.
- (IBAction) checkVersion: (id) sender {
[NSThread detachNewThreadSelector: @selector(checkVersionInThread:)
toTarget: self withObject: sender];
}
- (void) checkVersionInThread: (id) sender {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSDictionary *versionDict = [NSDictionary
dictionaryWithContentsOfURL: versionsURL];
if (versionDict != nil) {
// do stuff
} else {
NSLog(@"Unable to download version information.");
}
[pool release];
[NSThread exit];
}

You might save yourself some trouble and take a look at
DTCVersionManager -- http://los.dtcurrie.net/code/
I think Uli Kusterer also wrote some sort of version management class
or framework as well.
