iphone - how to convert byte code into pdf in ios when hit url in ios -

this 1 of activity hit url using nsurl connection , parse data , json data data in byte code as
nsstring *ptr= { 82, 111, 111, 116, 32, 50, 32, 48, 32, 82, 10, 47, 83, 105, 122, 101, 32, 51, 50, 10, 47, 73, 110, 102, 111, 32, 49, 32, 48, 32, 82, 10, 62, 62, 10, 115, 116, 97, 114, 116, 120, 114, 101, 102, 10, 49, 52, 51, 52, 50, 55, 10, 37, 37, 69, 79, 70, 10.........etc }

i got in nsstring , after

  nsmutablearray *bytes=[[nsmutablearray alloc]init];   [bytes addobject:ptr];    nsmutabledata *data = [[nsmutabledata alloc] initwithcapacity:bytes.count];   nslog(@"file %@",data);   (nsnumber *byteval in bytes)   {     byte b = (byte)(byteval.intvalue);     [data appendbytes:&b length:1];   }   nsarray *docdirectories = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);  nsstring *docdirectory = [docdirectories objectatindex:0];  nsstring *filename = [docdirectory stringbyappendingpathcomponent:@"abcd.pdf"];  nslog(@"file %@",filename);   [data writetofile:filename atomically:no];   nsstring *resourcedocpath = [[nsstring alloc] initwithstring:[[[[nsbundle mainbundle] resourcepath] stringbydeletinglastpathcomponent] stringbyappendingpathcomponent:@"documents"]];   nsstring *filepath = [resourcedocpath stringbyappendingpathcomponent:@"abcd.pdf"];   nsurl *targeturl = [nsurl fileurlwithpath:filepath];  nsurlrequest *requestfile = [nsurlrequest requestwithurl:targeturl];   nslog(@"request path %@",requestfile); 

this output. creates pdf can't understand how open , see generated pdf file.

request path <nsurlrequestfile://localhost/users/rahulsharma/library/application%20support/iphone%20simulator/6.1/applications/cd29ed82-8039-411f-8bba-2784e5445ede/documents/abcd.pdf> 

please me solve problem on how pdf.

 nsstring *responsetext;  nsmutablearray *bytearray; viewdidload {   [self report];  } -(void)report { finished=false; nsstring *case_id=[nsstring stringwithformat:@"8cc61590-42b0-4433-b8ee-25e40d5e6033"];  nsstring *investigation_id=[nsstring stringwithformat:@"33a8b03f-4ad2-424a-8aa9-02a07d3937eb"]; nsstring *test_id=[nsstring stringwithformat:@"e5a7e867-422c-4365-b920-87fdf5d82783"];   dictionary = [nsmutabledictionary dictionary];  [dictionary setobject:case_id forkey:@"caseid"]; [dictionary setobject:investigation_id forkey:@"investigationid"]; [dictionary setobject:test_id forkey:@"testid"]; // [dictionary setobject:procedure forkey:@"proc"]; // [dictionnary setobject:count  forkey:@"count"]; nslog(@"dict %@",dictionary); nserror *error = nil; nsdata *jsondata = [nsjsonserialization datawithjsonobject:dictionary options:kniloptions error:&error]; nslog(@"json %@",jsondata); nsurl *url1 = [nsurl urlwithstring:@"http://192.168.1.202:81/laboratorymodule/lisservice.asmx/getpatienttestreport"]; nslog(@"url %@",url1);  nsmutableurlrequest *request = [nsmutableurlrequest requestwithurl:url1]; [request sethttpmethod:@"post"];  [request addvalue: @"application/json; charset=utf-8" forhttpheaderfield:@"content-type"];  [request sethttpbody:jsondata]; nsurlconnection *theconnection = [[nsurlconnection alloc] initwithrequest:request delegate:self];  if( theconnection ) {     webdata = [nsmutabledata data] ;     nslog(@"%@",webdata);  } else {     nslog(@"theconnection null"); } while(!finished) {     [[nsrunloop currentrunloop] runmode:nsdefaultrunloopmode beforedate:[nsdate distantfuture]]; } 

}

 -(void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response {   [webdata setlength: 0];  nslog(@"web = %@",webdata); } -(void)connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data { [webdata appenddata:data]; nslog(@"web = %@",webdata);  } -(void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error { nslog(@"error theconenction");  } -(void)connectiondidfinishloading:(nsurlconnection *)connection {  responsetext = [[nsstring alloc] initwithdata:self.webdata encoding:nsutf8stringencoding]; nslog(@"val %@",responsetext);  sbjsonparser *par=[[sbjsonparser alloc]init]; nsstring *filecontent=[[nsstring alloc]initwithstring:responsetext]; nsdictionary *data=(nsdictionary*)[par objectwithstring:filecontent error:nil]; nslog(@" data %@",data); bytearray=[data objectforkey:@"d"]; nslog(@" string %@",bytearray);   nslog(@"done. received bytes: %d", [webdata length]);  finished=true;        } 

if want open , view pdf file in iphone can use uiwebview open , show pdf file. pass requestfile in -

[webview loadrequest:requestfile]; 

here webview variable name uiwebview.
