我正在使用Parse将数据加载到我的Today Extension中，然后更新我的Widget文本字段。今天的扩展名“无法加载”
当我运行我的代码似乎没有问题，实际上调试我的扩展中的代码我将该函数复制到我的主应用程序，并运行它，所以我可以看到输出（我知道这是可能的调试窗口小部件但它似乎是一个非常混乱和麻烦的过程）。所有的输出都是正确的，所以当我的Widget无法正常工作时，我完全傻眼了。
我认为它没有在我的小部件扩展中工作，因为我在我的小部件视图中得到“无法加载”文本字段。
我使用的功能称为“update_widget”，我称之为“update_widget”在“super.viewDidLoad（）”在我的窗口小部件“TodayViewController”
难道我更新我的插件在错误的方式？
任何想法为什么这可能是？
“TodayViewController.swift”的代码如下。假设解析ID和查询ID是正确的，而不是“HiFriends”。假设Day类被写入并正常工作。最后请记住，如果我在主应用程序“AppDelegate.swift”中粘贴“update_widget”，则所有输出都是正确的，并且不会崩溃。挖掘。
此外，如果它有帮助，我注意到，在显示“无法加载”之前，小部件显示“加载”，我在“update_widget”函数查询之前打印。

我建议，不要告诉我们有关您的代码的故事，而是发布实际无法使用的代码和尽可能多的诊断信息。 – nhgrif
这个东西是函数工作中的代码，因为它在我的“AppDelegate”中起作用，所以它不能是源自函数的错误。会看到我的“TodayViewController”帮助吗？ @nhgrif –
这是一个开始，是的。 – nhgrif
