I am developing an email client using Chilkat Email Client Library. Many times users drag and drop images in the email body and send the email. Is there any API to retrieve/show such images?
Hi! You should use related items of image MIME type. Chilkat Email object contains related items and related items count. I use C# but I think that in your case code wil be the same.
Well I used the following to embed images in my WebView:
#import <AssetsLibrary/AssetsLibrary.h> /// REMEMBER TO ADD FRAMEWORK TO LINKER
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Obtain the path to save to
NSString *documentsDirectory = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
// Get selected image filename
__block NSString *imagePath = nil;
NSURL *refURL = [info valueForKey:UIImagePickerControllerReferenceURL];
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *imageAsset) {
ALAssetRepresentation *imageRep = [imageAsset defaultRepresentation];
// Get path with filename at end
imagePath = [documentsDirectory stringByAppendingPathComponent:[imageRep filename]];
// Save the selected image inside the app
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
NSData *data = UIImagePNGRepresentation(image);
// If image is saved, insert the image from correct path
if ([data writeToFile:imagePath atomically:YES]) {
// Embed the image into the webview (email)
NSString *imageTag = [NSString stringWithFormat:@"\n<img src=\"%@\" width=\"100%%\"><br><br>", imagePath];
NSString *oldHTML = [_emailBodyWebView stringByEvaluatingJavaScriptFromString:@"document.documentElement.innerHTML"];
NSString *newHTML = [NSString stringWithFormat:@"<html contenteditable=\"true\">%@%@</html>", oldHTML, imageTag];
NSLog(@"\n\n NEW HTML: \n\n%@ \n\n >>> \n\n", newHTML);
[_emailBodyWebView loadHTMLString:newHTML baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]];
[_embededImages addObject:@{@"ImagePath": imagePath, @"ImageTitle": [imageRep filename]}];
} else {
NSLog(@"Couldn't save photo to Documents directory!");
[picker dismissViewControllerAnimated:YES completion:nil];
return;
}
// Dismiss Photo Picker
[picker dismissViewControllerAnimated:YES completion:^{ [_emailBodyWebView reload]; }];
};
ALAssetsLibrary *assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:refURL resultBlock:resultblock failureBlock:nil];
}
In your "Sending Email Method":
NSLog(@"_embededImages: %@", _embededImages);
CkoEmail *email = [[CkoEmail alloc] init];
for (int x = 0; x < images.count; x++) {
NSString *imagePath = [[_embededImages objectAtIndex:x] valueForKey:@"ImagePath"];
NSString *imageTitle = [[_embededImages objectAtIndex:x] valueForKey:@"ImageTitle"];
[email AddRelatedFile2:imagePath filenameInHtml:imageTitle];
}
Few problems here. When embedding images, the title will be the imagePath name, if you twist them they wont work lol but you can play around with this as I just stopped using embedded images and will do everything as attachments only.
If you added the images, and delete them from WebView, they will still be in the "_embededImages" array for sending, so when you delete the images, it will still send.
I pasted this to help you, so feel free to continue and finish it off as I won't continue with embedded images. Hope this helps a little. :)
