Attaching a mp3 file to email directly from app? - iphone

Question

I am working on an app where, if the user selects a sound, they can email it to themselves from the app.
The attachment part 'appears' to work, however, when I send the email, the recipient has no attachment?
On the iPad/iPhone itself, it looks like it is attaching it when it comes to compose, but it is not working? :/
Here is the code I am using;
- (void)onSend:(id)sender{
int nIndex;
UIButton *btnSender = (UIButton *)sender;
NSLog( #"%d", btnSender.tag );
for ( int i = 0; i < [ m_aryFileName count ]; i++ ) {
if( i == ( btnSender.tag - 100 ) ){
nIndex = i;
}
}
NSString *strFileName = [ m_aryFileName objectAtIndex:nIndex ];
strFileName = [ strFileName stringByAppendingString:#".mp3" ];
NSData* nData = [ NSData dataWithContentsOfFile:strFileName ];
MFMailComposeViewController *pickerMail = [[MFMailComposeViewController alloc] init];
pickerMail.mailComposeDelegate = self;
[pickerMail setSubject:#"myMail Attachment"];
// Attach an image to the email
[pickerMail addAttachmentData:nData mimeType:#"audio/mp3" fileName:strFileName ];
// Fill out the email body text
NSString *emailBody = #"Here is your attachment";
[pickerMail setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:pickerMail animated:YES];
[pickerMail release];
}

try this code mate,
NSString *strFileName = [m_aryFileName objectAtIndex:nIndex];
strFileName = [strFileName stringByAppendingString:#".mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:strFileName];
NSData *nData = [[NSData alloc] initWithContentsOfURL:fileURL];
MFMailComposeViewController *pickerMail = [[MFMailComposeViewController alloc] init];
pickerMail.mailComposeDelegate = self;
[pickerMail setSubject:#"myMail Attachment"];
[pickerMail addAttachmentData:nData mimeType:#"audio/mpeg" fileName:strFileName ];
NSString *emailBody = #"Here is your attachment";
[pickerMail setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:pickerMail animated:YES];

Below code might be useful to you:
NSData *videoData = [NSData dataWithContentsOfURL:mediaUrl];
[mailcomposer addAttachmentData:videoData mimeType:#"video/mp4" fileName:#"Video"]

Answer 3

Try using a mime type of audio/mpeg instead. You can get this value by running the following code:
#import <MobileCoreServices/MobileCoreServices.h>
CFStringRef uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension,
(__bridge CFStringRef)#"mp3",
NULL);
CFStringRef mimeTags = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType);
CFRelease(uti);
NSString *mediaType = [NSString stringWithString:(__bridge NSString *)mimeTags];
CFRelease(mimeTags);
How does that work?

if ([MFMailComposeViewController canSendMail] && m_pDataArray != nil)
{
NSString * pSongPath = [[NSBundle mainBundle] pathForResource:#"song" ofType"#"mp3"]; ;//get the file
MFMailComposeViewController * pMailComposer = [[MFMailComposeViewController alloc] init];
pMailComposer.mailComposeDelegate = self;
[pMailComposer setMessageBody:#"msg body" isHTML:NO];
NSURL * pFileUrl = [[[NSURL alloc] initFileURLWithPath:pSongPath] autorelease];
NSData * pData = [[[NSData alloc] initWithContentsOfURL:pFileUrl] autorelease];
[pMailComposer addAttachmentData:pData mimeType:#"audio/mpeg" fileName:#"song.mp3" ]];
[self presentModalViewController:pMailComposer animated:YES];
[pMailComposer release];
}
else
{
UIAlertView *pAlert = [[UIAlertView alloc] initWithTitle:#"Failure" message:#"Your device doesn't support the composer sheet" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[pAlert show];
[pAlert release];
pAlert = nil;
}
be sure that the file should have valid extension like .mp3 , in that case it will work properly
