I'm querying the 'Chat' class to fetch messages from Parse. Then using JSQMessagesViewController to display the fetched messages.
All works fine, until I try to cache the query using:
query.cachePolicy = .CacheThenNetwork
The issue is the results aren't being cached, and query.hasCachedResult always return false.
The query is as follows:
let query = PFQuery(className: PF_CHAT_CLASS_NAME)
query.whereKey(PF_CHAT_GROUPID, equalTo: forGroupId)
query.whereKey(PF_CHAT_DELIVERTIME, lessThan: NSDate())
query.includeKey(PF_CHAT_USER)
query.orderByDescending(PF_CHAT_DELIVERTIME)
query.limit = 50
query.cachePolicy = .CacheThenNetwork
if query.hasCachedResult{
print("yes")
}
else{
print("no")
}
query.findObjectsInBackgroundWithBlock(completionBlock)
And the fetch and JSQMessagesViewController bit is done here:
ParseWrapper.getChatAvailable(forGroupId: groupId){
(objects, error) -> Void in
if error == nil {
self.messages.removeAll()
self.users.removeAll()
for object in (objects as [PFObject]!).reverse() {
self.addMessage(object)
}
if objects!.count > 0 {
self.tableViewScrollToBottom(true)
}
self.tableView.reloadData()
self.refreshControl.endRefreshing()
}
}
Has anyone for a clue what's wrong with this? .CacheThenNetwork works fine for other queries.
