如何用魔法記錄從特定上下文中簡單地刪除一組實體？

Question

let predicate = NSPredicate(format: "users.@count == 0") 

if let locations = PBOLocation.MR_findAllWithPredicate(predicate, inContext: context) as? [PBOLocation] { 
    for location in locations { 
     //what now?       
    } 
} 

我需要從特定的上下文中刪除每個建立的位置。

MR_deleteEntity，MR_deleteEntityInContext:方法不起作用

Answer 1

對於具體context：

for location in locations { 
    context.deleteObject(location) 
}
