Apple Watch Complication 数据应该存储在哪里？

Question

我需要存储由主要 Watch 应用程序（和 iPhone 应用程序）控制并显示在复杂功能中的数据。

If you need to fetch or compute the data for your complication, do it in your iOS app or in other parts of your WatchKit extension (for example, by scheduling a background app refresh task), and cache the data in a place where your complication data source can access it.

当他们告诉您将数据缓存在复杂功能可以访问的地方时，他们在想什么？实现此目标的最佳 practice/standard 方法是什么？

Answer 1

您可以在 UserDefaults 中存储一些数据，并从您的复杂数据源访问它。

即

//In a background task
func getComplicationData(){
    let yourData = someNetworkCall()
    /* 
    yourData = [
        "complicationHeader": "Some string",
        "complicationInner": "Some other stirng"
    ]


    */
    UserDefaults.standard.set(yourData, forKey: "complicationData")
}

然后在您的 ComplicationDataSource

func getCurrentTimelineEntry(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimelineEntry?) -> Void) {

    if let yourData = UserDefaults.standard.dictionary(forKey: "complicationData") as? [String: String] {
        //Handle setting up templates for complications
    }

}
