I am using AFHTTPRequestOperationManager (2.0 AFNetworking library) for a REST POST request. But the manager only have the call to set the parameters.

You could create your own custom subclass of AFHTTPRequestSerializer, and set this as the requestSerializer for your AFHTTPRequestOperationManager.

In this custom requestSerializer, you could override

- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request         
                               withParameters:(id)parameters 
                                        error:(NSError *__autoreleasing *)error;

Inside your implementation of this method, you'll have access to the NSURLRequest, so you could do something like this

- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request     
                               withParameters:(id)parameters 
                                        error:(NSError *__autoreleasing *)error  
{    
    NSURLRequest *serializedRequest = [super requestBySerializingRequest:request withParameters:parameters
     error:error];
    NSMutableURLRequest *mutableRequest = [serializedRequest mutableCopy];          
    // Set the appropriate content type
    [mutableRequest setValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];              
    // 'someString' could eg be passed through and parsed out of the 'parameters' value
    NSData *httpBodyData = [someString dataUsingEncoding:NSUTF8StringEncoding];
    [mutableRequest setHTTPBody:httpBodyData];

    return mutableRequest;
}

You could take a look inside the implementation of AFJSONRequestSerializer for an example of setting custom HTTP body content.
