【问题描述】：

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

【参考方案1】：

具体context：

for location in locations 
    context.deleteObject(location)
