iPhone發送的郵件中沒有附件

Question

我試圖通過MFMailComposeViewController作爲附件發送錄製的聲音文件。

聲音文件正常。

選取器顯示正確的文件名稱，將音頻文件圖標顯示爲附件，發送郵件，但結果中沒有附件。

我附在發送郵件的源下面。有一個「text/plain」內容類型部分，而不是「Content-Disposition：attachment」。如預期。

這是我的代碼來定義路徑並附加音頻文件。什麼可能是錯的？

#define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] 
#define FILEPATH [DOCUMENTS_FOLDER stringByAppendingPathComponent:[self dateString]] 

...

NSURL *url = [NSURL fileURLWithPath:FILEPATH]; 
self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; 

...

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
picker.mailComposeDelegate = self; 
NSURL *url = [NSURL fileURLWithPath: [NSString stringWithFormat:@"%@", [self.recorder url]]]; 
NSData *audioData = [NSData dataWithContentsOfFile:[url path]]; 
[picker addAttachmentData:audioData mimeType:@"audio/wav" fileName:[[url path] lastPathComponent]]; 

和發送的郵件的來源：

Answer 1

我發現[url path]不正確dataWithContentsOfFile，我用了[[self.recorder url] path]而不是它工作正常。
