我正在尝试使用来自IOS / iPhone的WatchConnectivity传输的数据更新watchOS2 clockkit复杂功能。
尽管进行了相当多的研究，但到目前为止还没有成功。我发现虽然其他帖子描述了类似的挑战（还没有解决方案）
我遇到了3个问题：
1）ComplicationController中的sendMessage似乎没有唤醒IOS Parent App（同时从InterfaceController发送的sendMessage会唤醒IOS Parent App）
2）即使将值传递给ComplicationController（通过sendUserInfoToComplication并且当IOS应用程序位于前台时），复杂化中显示的值有时也会更新（没有找到模式，为什么有时它会/有时不会）
3）我将“getNextRequestUpdate ..”设置为2分钟（用于测试目的）。但这似乎没有任何区别。 （在任意时间甚至在模拟器中被触发，但是没有使用“预算”/我设置塞子来验证）
请注意，我对IOS / Swift编程相对较新。但我认为，根据其他问题/帖子，我似乎并不是唯一一个在这方面苦苦挣扎的人。

此外，在运行Simulator时，我收到了大量类似的消息：
objc[7501]: Class SPAssetCacheAssets is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/Frameworks/WatchKit.framework/WatchKit and /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/PrivateFrameworks/SockPuppetGizmo.framework/SockPuppetGizmo. One of the two will be used. Which one is undefined.

像这样使用CLKComplicationServer：
CLKComplicationServer* server = [CLKComplicationServer sharedInstance];
[server.activeComplications enumerateObjectsUsingBlock:^(CLKComplication * _Nonnull each, NSUInteger idx, BOOL * _Nonnull stop) {
[server reloadTimelineForComplication: each];
}];
它会调用您的ComplicationController。

在模拟器中调试复杂功能时，每次从Xcode启动调试会话时都需要退出监视模拟器。如果不这样做，您将遇到7007错误导致的问题，并且不会调用getNextRequestedUpdateDateWithHandler。
这将更新您的并发症：
let server = CLKComplicationServer.sharedInstance()
server.activeComplications.forEach { server.reloadTimelineForComplication($0) }
