Apple Watch 通知问题:WatchKit 错误 - 无法找到要实例化的接口控制器类 [英] Apple Watch notification issue: WatchKit error - unable to find interface controller class to instantiate

问题描述

当我尝试动态推送通知控制器时出现以下错误.

I am getting the following error when I am trying to push my notification controller dynamically.

2015-03-30 13:18:53.324 MyApp WatchKit 扩展[79826:1951724]太长而无法显示自定义通知.回到静态.2015-03-30 13:26:13.831 MyApp WatchKit 扩展 [79826:1957863]WatchKit 错误 - 无法找到接口控制器类'_TtC26MyApp_WatchKit_Extension19InterfaceController' 实例化

2015-03-30 13:18:53.324 MyApp WatchKit Extension[79826:1951724] Took too long to show custom notification. Falling back to static. 2015-03-30 13:26:13.831 MyApp WatchKit Extension[79826:1957863] WatchKit error - unable to find interface controller class '_TtC26MyApp_WatchKit_Extension19InterfaceController' to instantiate

我听说可能存在故障，但据我所知，它只发生在 Xcode beta 上，而不是 Xcode 6.2.我将有关通知故事板的模块更改为观看套件扩展.

I heard there might be a glitch, but as far as I am concern it is only occurring on the Xcode beta and not Xcode 6.2. I change the module regarding the notification storyboard to watch kit extension.

感谢任何帮助或建议.

我正在使用苹果在处理 iWatch 通知时提供的自动生成的有效负载.

Edit : I am using the auto generated payload that apple provide when dealing with notifications for iWatch.

推荐答案

需要重新检查的两件事，

Two things to recheck,

• 当您创建 WKUserNotificationInterfaceController 的新子类时，您是否选择了Watchkit 扩展作为目标而不是 iOS 应用程序目标?您可以通过 Select Project > Select Watchkit Extension Target > Build Phases > Compile Sources 验证这一点.在这里您应该看到之前创建的 NotificationInterface.m 文件.如果您看不到，那么您在创建文件时选择了错误的目标.那么解决方案是您可以创建一个选择正确目标的新类.
• 在 Storyboard 中，确保正确添加了自定义类名.同样在有效负载文件中，类别名称应与设置为故事板场景的类别匹配，以避免将来出现错误.

• When you have created a new subclass of WKUserNotificationInterfaceController, Have you selected Watchkit extension as a target instead of iOS app target? You can verify this by Select Project > Select Watchkit Extension Target > Build Phases > Compile Sources. Here you should see NotificationInterface.m file created earlier. If you can't see then you have selected wrong target when creating a file. Then solution is you can create a new class with correct target selected.
• In Storyboard, make sure custom class name is correctly added. Also in Payload file, category name should match with category set to storyboard scene just to avoid future errors.
