This usually just fails for me when there is no network. Don't forget
to change the URL's and names for your specific need.
The file should be of the format:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>
<plist version="1.0">
<dict>
<key>peacock</key>
<string>0.0.3</string>
</dict>
</plist>
-(void)checkVersion:(BOOL)quiet {
NSString *currVersionNumber = [[[NSBundle bundleForClass:[self class]]
infoDictionary] objectForKey:@"CFBundleVersion"];
NSDictionary *productVersionDict = [NSDictionary
dictionaryWithContentsOfURL:[NSURL
URLWithString:@"http://www.geo.vu.nl/~jkool/peacock/version.xml";]];
NSString *latestVersionNumber = [productVersionDict valueForKey:@"peacock"];
if([productVersionDict count] > 0 ) { // did we get anything?
if([latestVersionNumber isEqualTo: currVersionNumber] && !quiet)
{
// tell user software is up to date
NSRunAlertPanel(NSLocalizedString(@"Your Software is
up-to-date", @"Title of alert when a the user's software is up to
date."),
NSLocalizedString(@"You have the most recent version
of Peacock.", @"Alert text when the user's software is up to date."),
NSLocalizedString(@"OK", @"OK"), nil, nil);
}
else if( ![latestVersionNumber isEqualTo: currVersionNumber])
{
// tell user to download a new version
int button = NSRunAlertPanel(NSLocalizedString(@"A New
Version is Available", @"Title of alert when a the user's software is
not up to date."),
[NSString stringWithFormat:NSLocalizedString(@"A new
version of Peacock is available (version %@). Would you like to
download the new version now?", @"Alert text when the user's software
is not up to date."), latestVersionNumber],
NSLocalizedString(@"OK", @"OK"),
NSLocalizedString(@"Cancel", @"Cancel"), nil);
if(NSOKButton == button)
{
[[NSWorkspace sharedWorkspace] openURL:[NSURL
URLWithString:@"http://www.geo.vu.nl/~jkool/peacock/";]];
}
}
} else {
if (!quiet) {
// tell user error occured
NSRunAlertPanel(NSLocalizedString(@"Version Check has
Failed", @"Title of alert when the version check has failed."),
NSLocalizedString(@"An error occured whilst trying to
retrieve the current version number from the internet.", @"Alert text
when the when the version check has failed."),
NSLocalizedString(@"OK", @"OK"), nil, nil);
}
}
}
