I try save relation this way
[pfBill pinInBackgroundWithBlock:^(BOOL succeeded, NSError *PF_NULLABLE_S error)
{
[relation addObject:pfBill];
[pfObjectWithRelations pinInBackgroundWithBlock:^(BOOL succeeded, NSError *PF_NULLABLE_S error)
{
}];
}];
But i can't do it.
PFRelation *relation = [[PFUser currentUser] relationForKey:@"Relation"];
PFQuery *query = [[relation query] fromLocalDataStore];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error){
NSLog(@"%@", objects);
}];
it returns nothing, but if i save relation with saveEventually its return some objects from local datastore
Save the object and pin it on success. Until an object is saved (or pushed to saveEventually
IIRC) it doesn't have an objectId
and isn't considered as a 'valid' object (so you also can't add it to a relationship).
