swift – 启动App的WatchOS3复杂功能

我想为watchOS 3创建一个复杂功能,只需启动我的应用程序.我用XCode创建了ComplicationController：

class ComplicationController: NSObject,CLKComplicationDataSource
{

    // MARK: - Timeline Configuration

    func getSupportedTimeTravelDirections(for complication: CLKComplication,withHandler handler: @escaping (CLKComplicationTimeTravelDirections) -> Void) {
        handler([.forward,.backward])
    }

    func getTimelinestartDate(for complication: CLKComplication,withHandler handler: @escaping (Date?) -> Void) {
        handler(nil)
    }

    func getTimelineEndDate(for complication: CLKComplication,withHandler handler: @escaping (Date?) -> Void) {
        handler(nil)
    }

    func getPrivacyBehavior(for complication: CLKComplication,withHandler handler: @escaping (CLKComplicationPrivacyBehavior) -> Void) {
        handler(.showOnLockScreen)
    }

    // MARK: - Timeline Population

    func getCurrentTimelineEntry(for complication: CLKComplication,withHandler handler: @escaping (CLKComplicationTimelineEntry?) -> Void) {
        // Call the handler with the current timeline entry
        handler(nil)
    }

    func getTimelineEntries(for complication: CLKComplication,before date: Date,limit: Int,withHandler handler: @escaping ([CLKComplicationTimelineEntry]?) -> Void) {
        // Call the handler with the timeline entries prior to the given date
        handler(nil)
    }

    func getTimelineEntries(for complication: CLKComplication,after date: Date,withHandler handler: @escaping ([CLKComplicationTimelineEntry]?) -> Void) {
        // Call the handler with the timeline entries after to the given date
        handler(nil)
    }

    // MARK: - Placeholder Templates

    func getLocalizableSampleTemplate(for complication: CLKComplication,withHandler handler: @escaping (CLKComplicationTemplate?) -> Void) {
        // This method will be called once per supported complication,and the results will be cached
        handler(nil)
    }

}

并为Circular,Modular和Utilitarian资产添加了图像.但是当我运行Watch App时,我无法选择Watch脸的并发症.我还需要做什么？

谢谢

解决方法

这些代码更改是必需的：

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


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

        let template = CLKComplicationTemplateCircularSmallRingImage()
        template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Circular")!)
        let timelineEntry = CLKComplicationTimelineEntry(date: Date(),complicationTemplate: template)
        handler(timelineEntry)

    } else if complication.family == .utilitarianSmall
    {

        let template = CLKComplicationTemplateUtilitarianSmallRingImage()
        template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Utilitarian")!)
        let timelineEntry = CLKComplicationTimelineEntry(date: Date(),complicationTemplate: template)
        handler(timelineEntry)

    } else if complication.family == .modularsmall
    {

        let template = CLKComplicationTemplateModularsmallRingImage()
        template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Modular")!)
        let timelineEntry = CLKComplicationTimelineEntry(date: Date(),complicationTemplate: template)
        handler(timelineEntry)

    } else {

        handler(nil)

    }

}


func getLocalizableSampleTemplate(for complication: CLKComplication,withHandler handler: @escaping (CLKComplicationTemplate?) -> Void)
{        
    switch complication.family
    {
        case .circularSmall:
            let image: UIImage = UIImage(named: "Circular")!
            let template = CLKComplicationTemplateCircularSmallSimpleImage()
            template.imageProvider = CLKImageProvider(onePieceImage: image)
            handler(template)
        case .utilitarianSmall:
            let image: UIImage = UIImage(named: "Utilitarian")!
            let template = CLKComplicationTemplateUtilitarianSmallSquare()
            template.imageProvider = CLKImageProvider(onePieceImage: image)
            handler(template)
        case .modularsmall:
            let image: UIImage = UIImage(named: "Modular")!
            let template = CLKComplicationTemplateModularsmallSimpleImage()
            template.imageProvider = CLKImageProvider(onePieceImage: image)
            handler(template)
        default:
            handler(nil)
    }
}

此外,您需要在扩展中提供图像作为资产.
