iOS Image upload via AFNetworking 2.0

Question

I've been looking examples for the new AFNetworking 2.0 to upload images. But I'm hitting wall and couldn't figure out what's wrong with the code. So this is the code I used

NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];


AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://myserverurl.com"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromData:imageData progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Success: %@ %@", response, responseObject);
    }
}];
[uploadTask resume];

TIA

I ended up using the multi-part request

UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFormData:imageData name:@"image"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

`appendPartWithFileData:imageData name:@"image" error:nil]` is not working anymore, I guess. You should use: `[formData appendPartWithFormData:imageData name:@"image"];` ...but still it doesn't work for me :/ – raistlin Nov 07 '13 at 14:43

and why do you even bother with fileURl if you're not using it after? – raistlin Nov 07 '13 at 14:44

@raistlin `appendPartWithFileData` worked for me as well. see http://stackoverflow.com/a/20190352/1933185 – jerik Nov 25 '13 at 10:59

@raistlin I think you mean "filePath," which indeed does not seem to be used here. – carbocation May 24 '14 at 05:25
@ordinaryman09 do u know how to add Header values with an image? – Ushan87 Jan 29 '15 at 10:41
In my case it worked after add this: `[formData appendPartWithFileData:img_data name:@"add_file[]" fileName:@"abc.png"mimeType:@"image/png"];` – Bhavin Ramani Jun 04 '16 at 12:07
