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

Question

this is one of my activity I hit a url using NSURL connection and then Parse this data and get JSON data this data in byte code like 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 this in a NSString and after this

  NSMutableArray *bytes=[[NSMutableArray alloc]init];
  [bytes addObject:ptr];

  NSMutableData *data = [[NSMutableData alloc] initWithCapacity:bytes.count];
  NSLog(@"file %@",data);
  for (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 is output. It creates pdf but i can't understand how to open and see the generated pdf file.

If you want to open and view PDF file in iPhone then you can use a UIWebView to open and show a PDF file. Pass this requestFile in this -

[webView loadRequest:requestFile];

here webView is the variable name for UIWebView .
