これは私のアクティビティの 1 つで、NSURL 接続を使用して URL をヒットし、このデータを解析して、 NSString *ptr= { 82, 111, 111, 116, 32, 50, 32, 48, のようなバイト コードでこのデータを取得します。 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. ........など}

これを NSString で取得し、この後

  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);

これが出力されます。PDFを作成しますが、生成されたPDFファイルを開いて表示する方法がわかりません。
ファイル /Users/rahulsharma/Library/Application Support/iPhone Simulator/6.1/Applications/CD29ED82-8039-411F-8BBA-2784E5445EDE/Documents/abcd.pdf

iPhoneでPDFファイルを開いて表示したい場合は、を使用してUIWebViewPDFファイルを開いて表示できます。これをこれに渡すrequestFile-

[webView loadRequest:requestFile];

webViewの変数名は次のとおりですUIWebView。
