In my application I am dealing with uploading of images. My images are in documents directory. I am using NSFileManager to get the data from it and converting to base 64 encoding. Everything goes good while uploading. But after successful uploading of images it shows 100MB allocations out of which around 54MB are shown for CFString. Can anybody guide me for the reason of CFString allocation?

Code snippet:

  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSFileManager *fileMngr=[NSFileManager defaultManager];

  NSString *strZipPath= [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.zip",strRandomFolderName]];
  NSData *dat=[[NSData alloc] initWithContentsOfFile:strZipPath];
  NSString *strZipEncoded =[dat encodeBase64ForData];

strZipEncoded is sent to server using webmethod.

Please find images for more information.

Thanks.

Can you add some of your code please? – Janak Nirmal Sep 17 '13 at 04:43
You can use Instruments to show what's responsible for doing all those CFString allocations. – Michael Dautermann Sep 17 '13 at 04:49
@Michael Dautermann As my second image shows responsible is only foundation and no other detail info given related to my code. – Pooja M. Bohora Sep 17 '13 at 04:53
@ Janak Nirmal I updated the question please check the code. – Pooja M. Bohora Sep 17 '13 at 04:56
What are you doing inside `encodeBase64ForData` ? – borrrden Sep 17 '13 at 06:20
It's classes for encoding taken from github. NSData+Base64Additions.m – Pooja M. Bohora Sep 17 '13 at 06:33
To add more to this I am using NSMutableString and appendformat to create soap envelope for web method. – Pooja M. Bohora Sep 17 '13 at 07:08
May I get any hint on this? :( – Pooja M. Bohora Sep 20 '13 at 06:42
