how to email file from documents directory of iphone app - iphone

Question

I am saving file documents directory after that i want to send that file in email but problem is that it doest not get attached i think problem is due path conflict or anything else here is the code where i save file.
// Retrieves the document directories from the iOS device
NSArray* documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString* documentDirectory = [documentDirectories objectAtIndex:0];
NSString* documentDirectoryFilename = [documentDirectory stringByAppendingPathComponent:aFilename];
// instructs the mutable data object to write its context to a file on disk
[pdfData writeToFile:documentDirectoryFilename atomically:YES];
NSLog(#"documentDirectoryFileName: %#",documentDirectoryFilename);
and here is the code which i am using for sending this file in email
- (NSString *)pathForFile : (NSString *) fileName{
return [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent: fileName];
}
- (void) sendMailWithAttachedFile : (NSString *) fileName :(NSString *) extension{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
// NSURL* outputURL = [[NSURL alloc] initFileURLWithPath:[self pathForResourse:fileName ofType:extension]];
NSURL* outputURL = [[NSURL alloc] initFileURLWithPath:[self pathForFile:[NSString stringWithFormat:#"%#.%#", fileName, extension]]];
NSData *data=[[NSData alloc]initWithContentsOfURL:outputURL];
[picker addAttachmentData:data mimeType:#"documents/pdf" fileName:#"TestOne.pdf"];
[self presentModalViewController:picker animated:YES];
}
-(IBAction)onEmailResultPDF{
[self sendMailWithAttachedFile:#"TestOne":#"pdf"];
}
