问题描述

限时删除！！

我有一个 UserToMessage 表，它有一个名为 thisUser 的用户指针和一个名为 msg

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

message table 有一个指向用户的指针，称为 creator.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"]

我也想[includeKey:@"creator"]不知何故...

推荐答案

这会起作用.

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
    ...
}];
