Sparkle

Using Sparkle for System Preference bundles

Asked by junkzilla

Hi,

I'm a Cocoa n00b so probably missing something obvious here. I installed Spakle for a normal app but now I would like to integrate it with a System Preference bundle I'm making. I tried to follow the wiki but the "Updating a Bundle" article is a little bit too advanced for me.

It's the part: "Instead, you should instantiate the SUUpdater instance for your bundle in code at an early stage, just after your bundle was loaded."that I don't understand. How do I do this?

I tried to add the [SUUpdater updaterForBundle:[NSBundle bundleForClass:[self class]] line to my awakeFromNib method but that does not compile, it doesn't know the SUUpdater there. How can I tell it where to look?

Is there any sample code available? Sorry for this super easy questions...

Thank you all!

Sorry for the confusion. There should really be some sample code.

It doesn't know what SUUpdater is because you have to #import <Sparkle.h>.

Somewhere in your code, you should write:
SUUpdater * updater = [SUUpdater updaterForBundle:[NSBundle bundleForClass:[self class]]];
[updater setAutomaticallyChecksForUpdates:YES];
[updater resetUpdateCycle];

Thanks Andy, that works! I forgot the Sparkle import.

Now, when I click the "Check for updates" button in my bundle (it's a preference pane bundle) it adds the SULastCheckTime to com.apple.systempreferences user defaults. I can see why but it feels wrong. What if another bundle in the system preferences is using Sparkle as well?

I checked the source code of Perian and they have a complicated separate update app. Is that the right way to do it? Can I add a namespace or something?

Yes, that's incorrect. Specifically, Sparkle will put the preference in the appropriate place for the bundle you provide in the code snippet I listed above. Note that the bundle being provided is [NSBundle bundleForClass:[self class]]. To be more explicit, try [NSBundle bundleWithIdentifier:@"com.you.foo"]
