Ios NSNotificationCenter刷新未经过addObserver的数据

当新数据从

WCSession

传入时，我需要使用

NSNotificationCenter

更新我，以便填写我的

表格视图

我在列出的每个函数上设置断点，但由于某种原因，它会直接转到
NSNotificationCenter.defaultCenter（）.addObserver（self，selector:“loadList:”，name:“load”，object:nil）
和，然后就没有其他地方了

有点不对劲，你能帮我吗？谢谢

似乎未调用
会话：didReceiveUserInfo:
。你能告诉我在你的代码中你在哪里使用数据管理器吗？我同意@thislooksfun，你是如何通过WCSession发送数据的？@thislooksfun是的，这似乎是正在发生的事情。我在上面发布了
doTable（）
中的
DataManager
用法，但是如果您在谈论其他内容，而我不知道您在说什么，请告诉我。将根据需要发布任何额外内容，谢谢@KyleRedfearn我的过程（一定是错误的）是：（
DataManager.swift
）->在
WCSession
->中获取数据，使用
NSNotificationCenter
发出通知，通知数据已通过
NSNotificationCenter.defaultCenter（）.postNotificationName（“load”，object:nil）
->（
InterfaceController.swift
）->通过
NSNotificationCenter.defaultCenter（）.addObserver（self，selector:“loadList:，name:“load”，object:nil）侦听并接收数据已从
DataManager
加载的通知
它调用…->
加载列表：
它只运行
doTable
->
doTable
加载表。您的流程正确，但需要在它之前添加一些项目。通过WCSession API将数据从应用程序发送到手表
