不能在iphone上发送带有视频/音频附件的电子邮件！ [英] Can't send email with video/audio attachment on iphone!

问题描述

我正在尝试通过MFMailComposeViewController发送电子邮件。我可以发送附有图像的电子邮件，但是当我尝试附加mp3或mp4文件时，我收到以下消息：

DA |无法打开锁文件/tmp/DAAccountsLoading.lock。我们会加载帐户，但可能会发生不良事情

（如果似乎在我开始填写To字段后出现），并且发送消息失败。

这是我的代码（HelperUtils类只是我创建的，我确定问题不在）：

  NSData * myData = [NSData dataWithContentsOfFile：[HelperUtils getPathWithEnding：media.name]]; 
 NSString * mimeTypeStr = [HelperUtils getMimeTypeOfFileWithPath：[HelperUtils getPathWithEnding：media.name]]; 
 NSLog（mimeTypeStr）; 
 NSLog（[HelperUtils getPathWithEnding：media.name]）; 
 [picker addAttachmentData：myData mimeType：mimeTypeStr fileName：media.name]; 
  

解决方案

  NSString * mp3File = [NSTemporaryDirectory（）stringByAppendingPathComponent：@tmp.mp3]; 
 NSURL * fileURL = [[NSURL alloc] initFileURLWithPath：mp3File]; 
 NSData * soundFile = [[NSData alloc] initWithContentsOfURL：fileURL]; 
 [mailDialogController addAttachmentData：soundFile mimeType：@audio / mpegfileName：@tmp.mp3]; 
  

适用于我的mp3文件。当你说mp4失败，以什么方式？

如果应用程序崩溃了几个，你最有可能存在内存泄漏。

I am trying to send an email with MFMailComposeViewController. I'm able to send emails with images attached, but when I try to attach mp3 or mp4 files I get this message:

DA|Could not open the lock file at /tmp/DAAccountsLoading.lock. We'll load the accounts anyway, but bad things may happen

(if seems to appear right after I start filling the "To" field), and sending the message fails.

Here is my code (The HelperUtils class is just something I created and I'm sure the problem is not there):

NSData *myData = [NSData dataWithContentsOfFile:[HelperUtils getPathWithEnding:media.name]];
NSString *mimeTypeStr = [HelperUtils getMimeTypeOfFileWithPath:[HelperUtils getPathWithEnding:media.name]];
NSLog(mimeTypeStr);
NSLog([HelperUtils getPathWithEnding:media.name]);
[picker addAttachmentData:myData mimeType:mimeTypeStr fileName:media.name];

解决方案

NSString *mp3File = [NSTemporaryDirectory() stringByAppendingPathComponent: @"tmp.mp3"];
NSURL    *fileURL = [[NSURL alloc] initFileURLWithPath:mp3File];
NSData *soundFile = [[NSData alloc] initWithContentsOfURL:fileURL];
[mailDialogController addAttachmentData:soundFile mimeType:@"audio/mpeg" fileName:@"tmp.mp3"];

works for me with mp3 files. when you say it fails with mp4, in what way?

if app is crashing after a few, you have a memory leak somewhere most likely.
