ios - Getting Warning with Parse.com -

i'm triying access each item on nsarray trough enumerateobjectsusingblock, since allow me utilize fast enumration , evaluating index.

when utilize findobjectsinbackgroundwithblock,

i warning: long-running operation beingness executed on main thread. break on warnblockingoperationonmainthread() debug.

as thought used in background not block mainthread. here code , i'm triying accomplish have 2 uiimageview container i'm pulling images result of relation on query. since there container tought improve evaluate index of nsarray.

not sure how can remedy warning.

thanks

[query findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error) { if (objects != 0) { [objects enumerateobjectsusingblock:^(pfuser *object, nsuinteger idx, bool *stop) { if (idx == 0) { pffile *userprofile = [object objectforkey:@"userpic"]; cell.promoter1.file = userprofile; cell.promoter1.contentmode = uiviewcontentmodescaleaspectfit; [cell.promoter1 loadinbackground]; cell.promoter1name.textalignment = nstextalignmentcenter; cell.promoter1name.linebreakmode = nslinebreakbywordwrapping; } if (idx == 1) { pffile *userprofile = [object objectforkey:@"userpic"]; cell.promoter2.file = userprofile; cell.promoter2.contentmode = uiviewcontentmodescaleaspectfit; [cell.promoter2 loadinbackground]; nsattributedstring *promoter1name; cell.promoter2name.textalignment = nstextalignmentcenter; *stop = yes; } }]; } }];

troubleshooting code, realized findobjectsinbackgroundwithblock not cause warning.

on part of code had this:

pfuser *user = [pfquery getuserobjectwithid:@"ebwfrl8pcf"]; [relation addobject:user]; [self.event saveinbackground];

which block main thread.

i apologize.
