如何从相关表中过滤数据（Parse）

Question

Hiii伙伴我要表，第一个是“用户”表，第二个是“PaidChatroom”表，这里是结构

这是我用于最近用户的代码，它工作正常。

PFGeoPoint *userGeoPoint=[PFGeoPoint geoPointWithLatitude:currentLocation.coordinate.latitude longitude:locationManager.location.coordinate.longitude];


PFQuery *query = [PFQuery queryWithClassName:@"_User"];  
[query whereKey:@"location" nearGeoPoint:userGeoPoint withinKilometers:5000.0];
arrAllUser=[[NSMutableArray alloc]init];


[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    arrAllUser=[objects mutableCopy];


}];

我只想要那些离我最近并购买约会的用户，我该如何过滤数据。

Answer 1

PFGeoPoint *userGeoPoint=[PFGeoPoint geoPointWithLatitude:currentLocation.coordinate.latitude longitude:locationManager.location.coordinate.longitude];


PFQuery *query = [PFQuery queryWithClassName:@"_User"];  
[query whereKey:@"location" nearGeoPoint:userGeoPoint withinKilometers:5000.0];
arrAllUser=[[NSMutableArray alloc]init];

[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error)
{
    arrAllUser=[objects mutableCopy];

    // Perform your second query here on the objects received inside this block for Purchased dating
}];
