嵌套包括Parse.com [英] Nested Include Parse.com

问题描述

我有一个 UserToMessage 表，其中有一个指向用户的指针，名为 thisUser ，并指向一个名为<$的消息指针c $ c> msg

I have a UserToMessage table which has a pointer to user called thisUser and a pointer to message called msg

消息表有一个指向用户的指针创建者。当我查询 UserToMessage 我 [includeKey：@message]

The message table has a pointer to user called creator. When I query UserToMessage I [includeKey:@"message"]

我还想 [includeKey：@creator] 以某种方式......

I also want to [includeKey:@"creator"] somehow...

推荐答案

这将有效。

PFQuery *query = [PFQuery queryWithClassName:@"UserToMessage"];
[query includeKey:@"msg"];
[query includeKey:@"msg.creator"];

// Add constraints on query
...
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if(error) return;
    // Do action
    ...
}];
