ios - Parse query finds two objects when there is only one -


i have following code find objects in custom class. reason finding 2 of same object (self.addedarray2's count 2, on parse data table online, there one). see why finding same object twice?

self.array2 = [[nsmutablearray alloc] init];     self.addedarray2 = [[nsmutablearray alloc] init];      pfquery *query = [pfquery querywithclassname:@"friends"];     [query wherekey:@"user" containsstring:[[pfuser currentuser] objectforkey:@"username"]];     [query findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error) {         (friends *currentfriend in objects) {             self.relation = currentfriend.friendsrelation;             self.addedrelation = currentfriend.addedrelation;             self.query = [_relation query];              [[_relation query] findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error) {                 [self.array2 addobjectsfromarray:objects];                  [[_addedrelation query] findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error) {                     [self.addedarray2 addobjectsfromarray:objects];                      [self.segmentcontrol settitle:[nsstring stringwithformat:@"friends (%lu)", (unsigned long)[self.array2 count]] forsegmentatindex:0];                     [self.segmentcontrol settitle:[nsstring stringwithformat:@"added me (%lu)", (unsigned long)[self.addedarray2 count]] forsegmentatindex:1];                     nslog(@"number 1: %@", [self.addedarray2 objectatindex:0]);                     nslog(@"number 2: %@", [self.addedarray2 objectatindex:1]);                  }];             }];         }     }];

it logging "number 1" "number 1" "number 2". looks code being run twice , adding again. how fix that? nesting, don't see can do.

for key "user" of friends class, if string holds user's username, try replacing:

[query wherekey:@"user" containsstring:[[pfuser currentuser] objectforkey:@"username"]];

with , let me know if changes anything:

[query wherekey:@"user" equalto:[[pfuser currentuser] objectforkey:@"username"]];

if pointer user object, however, want query resemble along these lines:

[query wherekey:@"user" equalto:[user currentuser]];

if either of assumptions wrong, let me know because not know structure of classes, try , figure out.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
