objective-c post data & image - objective-c

Question

I am new to objective-c and I have been searching for a way to send a post request to my server (based on Rest URL) but also include an image with it... I have found many methods to post data... and methods to post just an image, but nothing that combines the two...
I am searching for a wrapper, class or library because it seems to be a tedious task to write all this from scratch. I found the "ASIHTTPRequest" but this is no longer supported, although Ic an turn off ARC, I would prefer to find something still supported...
I also found AFNetworking, which seems to still be supported but I could be wrong, I just cannot find a solution to combine VERY simply data and a profile image...
Any help is appreciated?
Should I just use the ASIHTTPRequest library... ?? Or does anyone have any sample code for the AFNetworking library?
Here is the code I am using for AFnetworking library...
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
_emailAddressField.text, #"email",
_usernameField.text, #"username",
_passwordField.text, #"password",
nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:%"http://url.com/api/whatever/"];
[client postPath:#"/" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"Response: %#", text);
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"%#", [error localizedDescription]);
}];

If you're using AFNetworking, you can use multipartFormRequestWithMethod to upload an image:
// Create the http client
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseUrl:url];
// Set parameters
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys: #"param1", #"key1", nil];
// Create the request with the image data and file name, mime type, etc.
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:method path:#"url/to/" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:data name:nameData fileName:fileName mimeType:mimeType];
}];
And then you can add the upload progress block to get feedback of the upload process:
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
//Manage upload percentage
}];
Also, you can add setCompletionBlockWithSuccess to catch success and failure in your operation. More info can be found here. At last but not least important, add the request to the operation queue:
[httpClient enqueueHTTPRequestOperation:operation];
