An appcast item can specify a channel the update is posted to. Without specifying a channel, the appcast item is posted to the default channel.
|
|
For instance:
|
|
```
|
|
<item>
|
|
<sparkle:version>2.0 Beta 1</sparkle:version>
|
|
<sparkle:channel>beta</sparkle:channel>
|
|
</item>

```
|
|
|
|
This example posts an update to the @c beta channel, so only updaters that are allowed to use the @c beta channel can find this update.
|
|
|
|
If the @c <sparkle:channel> element is not present, the update item is posted to the default channel and can be found by any updater.
|
|
|
|
You can pick any name you'd like for the channel. The valid characters for channel names are letters, numbers, dashes, underscores, and periods.
|
|
|

|

This feature was added in Sparkle 2.

Please consider using or migrating to other supported features before adopting this method.
|

Specifically:
|
|
- If you want to filter out certain tagged updates (like beta updates), consider `-[SPUUpdaterDelegate allowedChannelsForUpdater:]` instead.
|
|
- If you want to treat certain updates as informational-only, consider supplying @c <sparkle:informationalUpdate> with a set of affected versions users are updating from.
|
|
|
|
If you're using special logic or extensions in your appcast, implement this to use your own logic for finding a valid update, if any, in the given appcast.
|
|
|
|
Do not base your logic by filtering out items with a minimum or maximum OS version or minimum autoupdate version
|
|
because Sparkle already has logic for determining whether or not those items should be filtered out.
|
|
|
|
Also do not return a non-top level item from the appcast such as a delta item. Delta items will be ignored.

Sparkle picks the delta item from your selection if the appropriate one is available.

If an item is available that has the same version as the application or bundle to update, do not pick an item that is worse than that version.
