title: combine two .caf files
body: <p>I have used below code to combine two .caf files.</p>
  
  <pre><code>NSMutableData *datas = [NSMutableData alloc];
  NSData *data1 = [NSData dataWithContentsOfFile:path1];
  NSData *data2 = [NSData dataWithContentsOfFile:path2];
  NSLog(@"file1 size  : %d", [data1 length]);
  NSLog(@"file2 size : %d", [data2 length]);
  [datas appendData:data1];
  [datas appendData:data2];
  NSLog(@"file3 size  : %d", [datas length]);
  [[NSFileManager defaultManager] createFileAtPath:combinedPath contents:datas attributes:nil];
  </code></pre>
  
  <p>Problem is; I can able to combine two files. But when I try to play the combined file, it is playing only the first file content.</p>
  
  <p>Please help me to resolve it.</p>
  
  <p>Thanks.</p>
