I could try! I don't know if you want to be following after me ;-)
there. I made a smiley.
Some of what I'm doing seems disgusting, but maybe I was cool to have figured it out.
You do have to setup some headers and things - or I did I guess.
On my server, I have a relationship from Person to an ERAttachment called "poster"
so in iOS I call that URL (blahblah/Person/999/poster.bplist or something) then you send it wrapped binary image data and some headers.
I had to pad the data to form a proper boundary format for multi-part handling like so:
[urlRequest addValue:@"image/png" forHTTPHeaderField:@"mimetype"];
[urlRequest addValue:@"image/png" forHTTPHeaderField:@"Mime-Type"];
[urlRequest addValue:@"photo.png" forHTTPHeaderField:@"filename"];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[urlRequest addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//Image
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filMyFile\"; filename=\"%@\"\r\n", @"poster.png"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/png\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:scaledImageData];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[urlRequest setHTTPBody:body];
And then I push all that to the server.
does that help?
oh, passing back down is as easy as anything else - I get my images from Amazon S3 like any web image.
let me know if you need help on that.
