ios - 发送带有相机图像附件的邮件

Question

有很多教程和信息介绍如何使用您的 iphone/ipad 应用程序发送附件，但使用预定义的图像或其他文件类型。但是我如何从我的 iphone/ipad 发送带有当前文件的邮件。更具体地说，是图像还是来自相机的图像？

干杯，谢谢

如果您使用 UIImagePickerController 来捕获图像，则与捕获图像时相比:

  #import <MobileCoreServices/UTCoreTypes.h> // framework MobileCoreServices.framework

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{    
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
    {
        UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
        [self sendMailWithImage:image];
    }
    [picker dismissModalViewControllerAnimated:NO];
}

- (void)sendMailWithImage:(UIImage *)image
{
     MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc]init];
     mailComposer.mailComposeDelegate = self;         
     // make sure you can make NSData from the object
     [mailComposer addAttachmentData:UIImageJPEGRepresentation(image, 1.0) mimeType:@"image/jpg" fileName:@"what ever you want to call the file"];
     [self presentViewController:mailComposer animated:YES completion:nil];
}
