如何使用 URI 方案在邮件中发送附件？企业 MDM 设备

Question

我正在为企业基础设施中的 MDM 设备开发应用程序。因此，MFMailComposeViewController 将不起作用。如何使用 URI 方案发送附件。还有其他选择吗？？

Answer 1

您需要为此创建 mimeType

例子：

    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];
