I want to unpin a list of objects, which I had successfully locally stored earlier, and replace it with a new one. The code below should do that trick, but the locally pinned objects simply don't get updated. I tried everything including PFObject.unpin, nothing removes the old pinned objects except a complete reset of the simulator
func updateCountryList(server:Int, local:Int) {
let query = VEPCountry.queryAll()
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]!, error: NSError!) -> Void in
if error != nil {
// throw error
} else {
if local != 0 {
VEPState.unpinAllObjectsWithName(String("countryListVersion\(local)"))
}
VEPState.pinAll(objects, withName: String("countryListVersion\(server)"))
defaults.setObject(server, forKey: "localCountryListVersion")
}
}
}
Appreciate help or pointer to known issues around unpinning in Swift
I wonder if your unpin has't really finished, it's going off to the database after all.
Can you try:
query
.findObjectsInBackground()
.continueWithSuccessBlock({ (task: BFTask!) -> AnyObject! in
// ...
return VEPState.unpinAllObjectsWithNameInBackground("name"))
})
.continueWithSuccessBlock({ (task: BFTask!) -> AnyObject! in
// ...
return VEPState.pinAllInBackground(objects, withName: "name"))
})
I may have the syntax a little off and the background method names not quite right. Also I'm using promises/tasks which is not a bad habit to get into.
