Question

有很多关于如何使用iphone / ipad应用程序发送附件的教程和信息，但有预定义的图像或其他文件类型。但是如何从我的iphone / ipad发送包含当前文件的邮件。更具体地说，来自相机的图像或图像？

干杯谢谢

Answer 1

如果您使用UIImagePickerController捕获图像，则捕获图像的时间为：

  #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];
}

Answer 2

MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc]init];
mailComposer.mailComposeDelegate = self;
UIImage *myImage = // some code to get your image or what ever file you want
// make sure you can make NSData from the object
[mailComposer addAttachmentData:UIImageJPEGRepresentation(imageToShare, 1.0) mimeType:@"image/jpg" fileName:@"what ever you want to call the file"];
[self presentViewController:mailComposer animated:YES completion:nil];
