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  }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
