我的iOS应用程序只是在NSRangeException上崩溃 – [NSManagedObjectContext save：].在任何地方找不到任何其他东西.我该如何解决这个问题？我没有任何内存地址或任何我可以使用的东西…

这是我用来保存的代码：thread-safe：
static var onceToken: dispatch_once_t = 0
static var singleton: CoreDataHelper!
static var sharedInstance: CoreDataHelper {
get {
dispatch_once(&onceToken,{
self.singleton = CoreDataHelper()
})
return singleton
}
}
我的xcdatamodeld(相关部分)：
编辑：我已经编辑代码来反映我的更改,使我的NSManagedObjectContext线程安全.我现在做的一切,我在CoreDataHelper的一个实例上进行了我上面的初始化.我发现我可以通过进入一个对话,添加消息,进入另一个会话并在那里添加消息来触发崩溃.我已经添加了我的xcdatamodeld.
解决方法
我已经将谈话和消息之间的一对多关系设定为“订购”.这是不正确的…我已经改变了我的NSManagedObject的类使用NSMutableSet而不是NSMutableOrderedSet.
显然这会导致save方法中的NSRangeException …
