将 GraphicCircular Apple Watch 并发症添加到现有 Xcode 项目

Question

我在网上找不到任何文档来解释如何添加 Watch Series 4 上提供的任何新的“图形”复杂功能。以下是我的步骤：

(1) 添加符合的类CLKComplicationDataSource（下面的代码） (2) 将并发症配置设置为指向 (1) 和 Complications asset 文件夹 (4) 从 Sketch 导出 png 并拖动到 Complications 资源文件夹中，以使用 Complications 资源文件夹中的模块化/实用/圆形图形（角、边框和圆形）占位符，该占位符不接受 png（仅限 pdf）。 毕竟，旧的模块化实用和圆形复杂功能工作正常，但是图形（角、边框和圆形）的图像（pdf）不会在设备上呈现

import ClockKit

class HockeyTrackerComplication: NSObject, CLKComplicationDataSource {
    func getSupportedTimeTravelDirections(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimeTravelDirections) -> Void) {
        handler([])
    }

    func getCurrentTimelineEntry(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimelineEntry?) -> Void) {
        if #available(watchOSApplicationExtension 5.0, *) {
            if complication.family == .circularSmall {

                let template = CLKComplicationTemplateCircularSmallRingImage()
                guard let image = UIImage(named: "Circular") else { handler(nil); return}
                template.imageProvider = CLKImageProvider(onePieceImage: image)
                let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
                handler(timelineEntry)

            } else if complication.family == .utilitarianSmall {

                let template = CLKComplicationTemplateUtilitarianSmallRingImage()
                guard let image = UIImage(named: "Utilitarian") else { handler(nil); return}
                template.imageProvider = CLKImageProvider(onePieceImage: image)
                let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
                handler(timelineEntry)

            } else if complication.family == .modularSmall {

                let template = CLKComplicationTemplateModularSmallRingImage()
                guard let image = UIImage(named: "Modular") else { handler(nil); return}
                template.imageProvider = CLKImageProvider(onePieceImage: image)

                handler(timelineEntry)

            } else if complication.family == .graphicCircular {
                let template = CLKComplicationTemplateGraphicCircularImage()
                guard let image = UIImage(named: "GraphicCircular") else { handler(nil); return}
                template.imageProvider = CLKFullColorImageProvider(fullColorImage: image)
                let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
                handler(timelineEntry)

            } else if complication.family == .graphicBezel {
                let template = CLKComplicationTemplateModularSmallRingImage()
                guard let image = UIImage(named: "GraphicBezel") else { handler(nil); return}
                template.imageProvider = CLKImageProvider(onePieceImage: image)
                let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
                handler(timelineEntry)

            } else if complication.family == .graphicCorner {
                let template = CLKComplicationTemplateGraphicCornerCircularImage()
                guard let image = UIImage(named: "GraphicCorner") else { handler(nil); return}
                template.imageProvider = CLKFullColorImageProvider(fullColorImage: image)
                let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
                handler(timelineEntry)

            } else {

                handler(nil)

            }
        } else {
            // Fallback on earlier versions
        }
    }

我的问题是，我没有实现getLocalizableSampleTemplate(for:withHandler:) https://developer.apple.com/documentation/clockkit/clkcomplicationdatasource/1650686-getlocalizedsampletemplate，而它被列为可选，而不是实现它所需的方法的一部分，CLKComplicationDataSource这使得我的图像显示在并发症。
