如何從相關表中過濾數據（解析）

Question

嗨，我必須要桌子，首先是“用戶”表，其次是“付費聊天室”表，這里是結構

這是我為最近的用戶使用的代碼，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];


}];

我只需要那些最接近我並購買了約會的用戶，我該如何過濾數據。

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
}];
