iphone - AFDownloadRequestOperation multipleDownload progress for each download -


i using afdownloadrequestoperation downloading. unable track progress of each download in queue. progress bar show progress of operation on main thread(which last added request). referred many links not able track progress whole block. here's code 

   (int =0; i<count; i++)     {         videoclass *item1=[[videoclass alloc]initwithvideo:[self.downloads objectatindex:i]];          nsmutableurlrequest *request = [[nsmutableurlrequest alloc] initwithurl:[nsurl urlwithstring:item1.url]];          nsstring *videotgtpath = [[[[videodbclass alloc] init] autorelease] getpathtovideofile:[self.downloads objectatindex:i]];          afdownloadrequestoperation *operation = [[afdownloadrequestoperation alloc] initwithrequest:request targetpath:videotgtpath shouldresume:yes];          [operation setcompletionblockwithsuccess:^(afhttprequestoperation *operation, id responseobject) {             nslog(@"successfully downloaded file %@", videotgtpath);              if ([[[[videodbclass alloc] init] autorelease] completedownload:item1 error:nil])             {                    nslog(@"successfully moved ");              }             self.alldownloads = [[[[videodbclass alloc] init] autorelease] getvideos];             [downloadtblview reloaddata];         }         failure:^(afhttprequestoperation *operation, nserror *error)          {             nslog(@"error: %@", error);         }];          [operation setprogressivedownloadprogressblock:^(afdownloadrequestoperation *operation1,nsinteger bytesread, long long totalbytesread, long long totalbytesexpected, long long totalbytesreadforfile, long long totalbytesexpectedtoreadforfile)          {              totalbytesreadforfile =  self.downloadcomplete;              totalbytesexpectedtoreadforfile = self.downloadsize;              nslog(@"the name of operation %@",operation1.request.url.absolutestring);             nslog(@"operation%i: bytesread: %d", 1, bytesread);             nslog(@"operation%i: totalbytesread: %lld", 1, totalbytesread);             nslog(@"operation%i: totalbytesexpected: %lld", 1, totalbytesexpected);             nslog(@"operation%i: totalbytesreadforfile: %lld", 1, totalbytesreadforfile);             nslog(@"operation%i: totalbytesexpectedtoreadforfile: %lld", 1, totalbytesexpectedtoreadforfile);       // progress view in section of tableview , updated reloading section shows same progress downloads.               [downloadtblview reloadsections:[nsindexset indexsetwithindex:1] withrowanimation:uitableviewrowanimationnone];          }];         //    [operation addobject:operation];         [operation start];     }

i know getting same progress because of 

 totalbytesreadforfile =  self.downloadcomplete;  totalbytesexpectedtoreadforfile = self.downloadsize;

as set value progressview. out of ideas how track progress each process , display it. me please.

use afhttpclient -enqueuebatchofhttprequestoperations:progressblock:completionblock: track progress of operations within batch. each operation completed, can increment progress block reflect (e.g. "5 or 19 operations finished").

tracking cumulative byte accumulation operations unnecessary; aforementioned approach sufficiently communicates progress user.

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 ...
