I am using parse for my iOS app and it works fine.
I wanted to implement offline feature so I am using pinInBackground
to save PFObject
to local database. But I can't retrieve it.
For my special reason, I've generated unique UUID
for every PFObject
pin name and used it.
{
...
NSString *uuid = [[NSUUID UUID] UUIDString];
[CustomObject pinInBackgroundWithName:uuID];
...
}
It returns success but I can't retrieve it.
Following is the query code to get pin Object
.
{
...
PFQuery *query = [CustomObject query];
[query fromLocalDatastore];
[query fromPinWithName:uuID];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error)
{
if(!error)
block(objects, nil);
else
block(nil, error);
}];
...
}
But objects has 0 elements always.
Any help would be greatly appreciated.
Thanks
Update:
This is the Pin object saved in parse local database.
{"isDeletingEventually":0,"className":"_Pin","__complete":true,"__operations":[{"_name":"16F31F2C-6375-4107-A0B6-FDCBA9810847","__updatedAt":{"__type":"Date","iso":"2017-07-02T18:33:02.825Z"},"_objects":[{"__type":"OfflineObject","uuid":"FF3D069C-864F-4D87-9511-F2738A5F95F4"}],"__uuid":"71BAF309-58D4-4BCC-82D8-BB35C25F1632"}]}
The problem was the query for local database.
I've changed the query like this and it worked for me.
{
...
PFQuery *query = [[[CustomObject query] fromLocalDatastore]ignoreACLs];
[query fromLocalDatastore];
[query fromPinWithName:uuID];
...
}
