Can’t send email with video/audio attachment on iphone!

所以在过去的几天里我一直在尝试通过电子邮件发送视频。我成功选择了视频，但我不知道如何将其放入电子邮件中。谢谢。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:NO completion:NULL];
    NSURL *mediaUrl = [info objectForKey:UIImagePickerControllerMediaURL];

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





    if ([MFMailComposeViewController canSendMail]){

        [mailcomposer setToRecipients:[NSArray arrayWithObjects:@"random@random.com", nil]];
        [mailcomposer setSubject:@""];
        [mailcomposer setMessageBody:@"" isHTML:NO];
        [mailcomposer addAttachmentData:mediaUrl mimeType:@"video/mp4" fileName:@"Video"];
        [self presentViewController:mailcomposer animated:YES completion:NULL];

    }


}

Answer 1

您要将 URL 添加为附件，您需要通过将该 URL 转换为数据来附加 NSData，如下所示

NSData *videoData = [NSData dataWithContentsOfURL:mediaUrl];

然后

[mailcomposer addAttachmentData:videoData mimeType:@"video/mp4" fileName:@"Video"];
