objective c - overwrite JSON data on server -


my app pulling down json file server (godaddy) , parsing array. user able add new record existing json. i'm running issues when try post of data server.

to clear, i'm trying overwrite existing file that's on server new data. know ftp isn't direction need going, i'm not using database of kind. files on server.

i've made sure json valid , i've called godaddy make sure don't need change permissions. i've used directory ftp before.

could remote_path_to_root_app_folder uses ftp credentials? if so, url need use?

- (void)postexamplesdictionarytoserver:(nonnull nsstring *)dname                                        :(nonnull nsstring *)rname                                        :(nonnull nsdata *)jsondata {     nsstring *userfileurlstring = [nsstring stringwithformat:@"%@/%@/%@tester.json", remote_path_to_root_app_folder, dname, rname];     nsurl    *userfileurl       = [nsurl urlwithstring:userfileurlstring];      nsstring *postlength        = [nsstring stringwithformat:@"%lu", (unsigned long)[jsondata length]];      nsmutableurlrequest *request = [[nsmutableurlrequest alloc] init];     [request seturl:userfileurl];     [request sethttpmethod:@"post"];     [request setvalue:postlength forhttpheaderfield:@"content-length"];     [request setvalue:@"application/json; charset=utf-8" forhttpheaderfield:@"content-type"];     [request sethttpbody:jsondata];      [[self.session uploadtaskwithrequest:request fromdata:jsondata completionhandler:^(nsdata *data, nsurlresponse *response, nserror *error)     {         nsstring *requestreply = [[nsstring alloc] initwithdata:data encoding:nsasciistringencoding];         nslog(@"error: %@", error);     }] resume]; }

edit: logged nserror passed completion handler , got this:

error: (null)

but...if change url file doesn't exist on server, this:

error: error domain=nsurlerrordomain code=-1008 "resource unavailable"      userinfo={nsunderlyingerror=0x7fca8ad44280 {error domain=kcferrordomaincfnetwork code=-1008 "(null)"},      nserrorfailingurlstringkey=ftp://*****:*****@ftp.*****.com/public_html/app/******/file.json,      nserrorfailingurlstringkey=ftp://*****:*****@ftp.*****.com/public_html/app/******/file.json, nslocalizeddescription=resource unavailable}

does mean it's not attempting upload task, request somehow?

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9,
