ios - iOS6 social framework bring up No Account Alert -

similar ios 6 social framework not going settings or no alert trying use slrequest:

i trying bring alert "no facebook account" when user has not logged in facebook in settings. have found alert appear after present slcomposeviewcontroller, rather inside if statement.

if([slcomposeviewcontroller isavailableforservicetype:slservicetypefacebook]) {     slcomposeviewcontroller *controller = [slcomposeviewcontroller composeviewcontrollerforservicetype:slservicetypefacebook];      //setup controller , callback code      [self presentviewcontroller:controller animated:yes completion:nil]; } 

however, trying use slrequest , dont want present slcomposeviewcontroller, instead, after checking accounts, popup alert. code here:

- (void)postimagefb { if([slcomposeviewcontroller isavailableforservicetype:slservicetypefacebook]) {     nslog(@"can post"); } else {     nslog(@"cant post"); }  acaccountstore *accountstore = [[acaccountstore alloc] init];  acaccounttype *accounttype = [accountstore accounttypewithaccounttypeidentifier:acaccounttypeidentifierfacebook];  nsarray *accountsarray = [accountstore accountswithaccounttype:accounttype]; nslog(@"accounts: %i", [accountsarray count]);  // possible popup alert here if accounts = 0?  nsdictionary *options = @{ acfacebookappidkey: @"123456789", acfacebookpermissionskey: @[@"publish_stream"], acfacebookaudiencekey: acfacebookaudiencefriends };  [accountstore requestaccesstoaccountswithtype:accounttype options:options completion:^(bool granted, nserror *error) {     if(granted) {          nsarray *accountsarray = [accountstore accountswithaccounttype:accounttype];          if ([accountsarray count] > 0) {              acaccount *facebookaccount = [accountsarray objectatindex:0];              nsdictionary *parameters = @{@"message": @"testing"};              slrequest *facebookrequest = [slrequest requestforservicetype:slservicetypefacebook                                                             requestmethod:slrequestmethodpost                                                                       url:[nsurl urlwithstring:@"https://graph.facebook.com/me/photos"]                                                                parameters:parameters];              [facebookrequest addmultipartdata: [self getimagedatafromplistwithfilename:@"image1.png"]                                      withname:@"source"                                          type:@"multipart/form-data"                                      filename:@"testimage"];              facebookrequest.account = facebookaccount;              [facebookrequest performrequestwithhandler:^(nsdata *responsedata, nshttpurlresponse *urlresponse, nserror *error)              {                  if (error) {                      nslog(@"%@",error.description);                  } else {                      nslog(@"responedata:%@", [[nsstring alloc] initwithdata:responsedata encoding:nsutf8stringencoding]);                  }               }];         }     } }];  } 

ok, have discovered isavailableforservicetype returns true? started testing on device.

i figured using invisible slcomposeviewcontroller bring alert seems suitable workaround:

if (![slcomposeviewcontroller isavailableforservicetype:slservicetypefacebook]) {      slcomposeviewcontroller *controller = [slcomposeviewcontroller composeviewcontrollerforservicetype:slservicetypefacebook];     controller.view.hidden = yes;     [self presentviewcontroller:controller animated:no completion:nil];  } else {      // put posting code here: slcomposeviewcontroller or slrequest  }
