如何使用 Magical Record 从特定上下文中简单地删除一组实体？

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?                        
    }
}

我需要从特定上下文中删除每个已建立的位置。

MR_deleteEntity、MR_deleteEntityInContext: 方法不起作用

Answer 1

具体context：

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