Question

我有一个UserToMessage表,其中有一个指向用户调用thisUser的指针和一个指向消息的指针msg

该message table有一个指针指向用户调用creator.当我查询UserToMessage我[includeKey:@"message"]

我也想以[includeKey:@"creator"]某种方式......

Answer 1

这会奏效.

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
    ...
}];

Answer 2

[includeKey:@"message.creator"]

你甚至可以更深入地做到这一点:message.creator.mother- 但不是更多.
