Sample

###1. Implement DrupalEntity: In order to implement drupal entity you just have to extend DrupalEntity, declare properties and implement following methods:

#####path this method should return relative path to entity on the server:

- (NSString *)path 
{
    return [NSString stringWithFormat:@"node/%@", self.nodeId];
}

#####requestGETParams this method should return get parameters:

- (NSDictionary *)requestGETParams 
{
    return @{@"page": self.page};       //  Path will be http://myserver.com/?page=10 if self.page value is 10
}

###2. Set server url

Set base url of server before first action with DrupalEntity object:

[DrupalAPIManager sharedDrupalAPIManager].baseURL = [NSURL URLWithString:@"http://myserver.com"];

####3. Instantiate DrupalEntity

BlogPage *bp = [BlogPage new];
bp.page = @(page);
[bp pullFromServer:nil];

###4. Using completion block

Completion block is defined as: typedef void (^EntityActionHandler)(id result);. If response was gotten and deserialized result is an DrupalEntity object otherwise nil.

[bp pullFromServer:^(id result) {
    if (!result) {
        //  Something went wrong, object was not pulled from server
    } else {
        //  Do something with object
    }
}];
