我处于为企业级应用程序开发MDM设备的情况。所以，MFMailComposeViewController将不起作用。我如何使用URI方案发送附件。有没有其他的选择？

您需要为

实例创建mime类型：

MFMailComposeViewController *mc = [[MFMailComposeViewController alloc]init]; 
    mc.mailComposeDelegate = self; 
    NSString *filePath = [[NSBundle mainBundle] pathForResource:filename ofType:extension]; 
    NSData *fileData = [NSData dataWithContentsOfFile:filePath]; 
    NSString *mimeType; 
    if ([extension isEqualToString:@"jpg"]) { 
     mimeType = @"image/jpeg"; 
    } else if ([extension isEqualToString:@"png"]) { 
     mimeType = @"image/png"; 
    } else if ([extension isEqualToString:@"doc"]) { 
     mimeType = @"application/msword"; 
    } else if ([extension isEqualToString:@"ppt"]) { 
     mimeType = @"application/vnd.ms-powerpoint"; 
    } else if ([extension isEqualToString:@"html"]) { 
     mimeType = @"text/html"; 
    } else if ([extension isEqualToString:@"pdf"]) { 
     mimeType = @"application/pdf"; 
    } 
    [mc addAttachmentData:fileData mimeType:mimeType fileName:filename]; 
    [self presentViewController:mc animated:YES completion:NULL];
