Uploading image with AFNetworking 2.0

I'm not sure which part (I think that some details were missing) was responsible, but I did it finally :) here you go:

-(void)uploadPhoto{    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"http://server.url"]];    NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);    NSDictionary *parameters = @{@"username": self.username, @"password" : self.password};    AFHTTPRequestOperation *op = [manager POST:@"rest.of.url" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {        //do not put image inside parameters dictionary as I did, but append it!        [formData appendPartWithFileData:imageData name:paramNameForImage fileName:@"photo.jpg" mimeType:@"image/jpeg"];    } success:^(AFHTTPRequestOperation *operation, id responseObject) {        NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"Error: %@ ***** %@", operation.responseString, error);    }];    [op start];}

Works like a charm :)

You can upload an image with AFNetworking using Swift like this...

    let compression = 0.5    let imageData = UIImageJPEGRepresentation("image", CGFloat(compression))if imageData != nil{   var manager = AFHTTPRequestOperationManager()        manager.responseSerializer.acceptableContentTypes = NSSet(array: ["text/html", "application/json"]) as Set<NSObject>        var dictParams = [        "familyId":"10000",        "contentBody" : "Some body content for the test application",        "name" : "the name/title",        "typeOfContent":"photo"    ]        let url = "http://...."        manager.POST(url, parameters: dictParams, constructingBodyWithBlock: { (formData: AFMultipartFormData!) -> Void in            //code            formData.appendPartWithFileData(imageData, name: "file", fileName: "filename", mimeType: "image/png")            }, success: { (operation:AFHTTPRequestOperation!, responseObject:AnyObject!) -> Void in                println(responseObject)            }, failure: { (operation:AFHTTPRequestOperation!, error:NSError!) -> Void in                println(error)        })    }

 UIImage *image = [UIImage imageNamed:@"decline_clicked.png"];NSData *imageData = UIImageJPEGRepresentation(image,1);NSString *queryStringss = [NSString stringWithFormat:@"http://your server/uploadfile/"];queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {     [formData appendPartWithFileData:imageData name:@"fileName" fileName:@"decline_clicked.png" mimeType:@"image/jpeg"]; }      success:^(AFHTTPRequestOperation *operation, id responseObject) {    NSDictionary *dict = [responseObject objectForKey:@"Result"];    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject); }      failure:^(AFHTTPRequestOperation *operation, NSError *error) {     NSLog(@"Error: %@ ***** %@", operation.responseString, error); }];
