objective c - Am I making two queries? -

-

since pffiles can retrieved through getdatainbackgroundwithblock because they're not objects (i think..) after making query i'm calling getdatainbackgroundwithblock convert pffile uiimage.

am making 2 queries calling findobjectinbackgroundwithblock , getdatabackgroundwithblock? if so, there way done 1 query only?

pfquery *query = [pfquery querywithclassname:@"photoobject"];      [query findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error){          (id object in objects) {               pffile *imagefile = object[@"photo"];             [imagefile getdatainbackgroundwithblock:^(nsdata *imagedata, nserror *error) {                 if (!error) {                      [self.annotationarray addobject:object[@"location"]];                     nslog(@"annotation's coordinate : %@", self.annotationarray);                       self.calloutimage = [uiimage imagewithdata:imagedata];                      self.geopoint = object[@"location"];                      cllocationcoordinate2d loccoord = cllocationcoordinate2dmake(self.geopoint.latitude, self.geopoint.longitude);                     custompin *pin = [[custompin alloc] initwithtitle:[object objectid] location:loccoord image:self.calloutimage];                     [self.mainmap addannotation:pin];                  }}];          }      }];

you're making 2 asynchronous network requests, 1 of requests -- findobjects -- query. find returns object points file, , in order file's contents, second (non-query) request required.

there way you're doing single request client: cloud function same thing posted code, , returns retrieved data.
