How to remove the path from an attachment when calling addAttachmentData?

When adding an attachment to an email, the file name gets it's complete path.
For a file located in:
/var/mobile/Applications/C3BBAA5F-07FE-4E26-9661-CB492E06BD2E/Documents/
I'm getting as a result, a file named:
_var_mobile_Applications_C3BBAA5F-07FE-4E26-9661-CB492E06BD2E_Documents_Clock.sqlite
When I need my filename to be:
Clock.sqlite
Here's my code:
NSString *path = [self getDatabaseFilePath];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"application/x-sqlite3"
fileName:path];
How can I get the attachment to have only the filename and extension,
without the complete path?
Thank you!
