Parse - Using relations versus pointers?

Question

I am using Parse as my backend. I have problems setting up the correct relation between objects.

I basically have a class named Post, each post belongs to a user(PFU

Answer 1

Create A PFSubClass like

yourClassName:PFObject with PFSubclassing 

and then in the header file create a Pointer relation

@property(nonatomic, strong) PFUser *userLikeRelation; 

add in m file add

+ (NSString *)parseClassName {

    return @"parseTableName";

}

+ (void)load {

    [self registerSubclass];

} 

finally in the View Controller set relation in query when you are save data in parse.

yourClassName *yourClassNameObj = [yourClassName objectWithClassName:[yourClassName parseClassName]];

[yourClassName setUserCommentRelation:[PFUser currentUser]];

for fetching data you can get data with include key

[yourClassNameObj includeKey:@"NameofRelation"];
