如何通過iPhone中的電子郵件發送.caf文件？

Question

我想在iphone中通過電子郵件發送帶.caf擴展名的音頻文件。任何人都可以幫助我做到這一點？我寫了mimeType:@"audio/caf"，但我認爲它不支持。請幫我做這個小任務。

使用下面的代碼： -

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filepath = [documentsDirectory stringByAppendingPathComponent:memo.memoUrl]; 

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filepath]; 
NSData *dataToSend = [[NSData alloc] initWithContentsOfURL:fileURL]; 
[fileURL release]; 

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
picker.mailComposeDelegate = self; 

[picker setSubject:@"Recording"]; 

// Set up recipients 
NSArray *toRecipients = nil; 
NSArray *ccRecipients = nil; 
NSArray *bccRecipients = nil; 

[picker setToRecipients:toRecipients]; 
[picker setCcRecipients:ccRecipients]; 
[picker setBccRecipients:bccRecipients]; 

[picker setMessageBody:@"" isHTML:YES]; 
[picker addAttachmentData:dataToSend mimeType:@"audio/x-caf" fileName:[NSString stringWithFormat:@"voice-memo.caf", memo.memoName]];
