REstkit Error on Get operation - ios

Question

I'm doing a Restkit GET operation but getting an error with Restkit. I tried the same operation with the REST COnsole on Chrome and it works:
DEtails of the GET operation are:
URL: https://www.ez-point.com/ezpoints
Operation: GET
Authorization Header: xxxxxxxxxxxxxxxxxxx
With the Chrome REST Console, it works and I get the proper response in JSON.
With Restkit, it doesn't work. THese are my Restkit codes:
//trying restkit
NSURL *endpoint = [NSURL URLWithString:#"https://www.ez-point.com/"];
RKObjectManager* objectManager = [RKObjectManager managerWithBaseURL:endpoint];
[objectManager.HTTPClient setAuthorizationHeaderWithToken:#"xxxxxxxxxxxxxxxxxxx"];
[objectManager getObjectsAtPath:#"ezpoints" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(#"Success");
//NSLog(mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"Failure");
//NSLog(operation);
//NSLog(error);
}];
I'm getting this error:

Any suggestion?

Answer 1

The error already gives a hint: it doesn't accept "text/xml" as a content type by default. Right now, it accepts
application/x-www-form-urlencoded
application/json
You can register it using RKMIMETypeSerialization and add "text/xml" to one of the accepted content types:
[RKMIMETypeSerialization registerClass:[RKXMLReaderSerialization class] forMIMEType:RKMIMETypeTextXML];
[objectManager setAcceptHeaderWithMIMEType:#"text/xml"];
