启动应用程序的WatchOS3并发症

问题描述

我想为watchOS 3创建一个复杂的功能，只需启动我的应用即可.我已经使用XCode创建了ComplicationController:

I would like to create a complication for watchOS 3 that will simply launch my App. I have used XCode to create the 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, limit: Int, 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)
    }

}

，并添加了用于循环"，模块"和功利"资产的图像.但是，当我运行Watch App时，我无法选择Watch面部的并发症.我还需要做什么?

and added images for the Circular, Modular and Utilitarian assets. But when I run the Watch App I cannot select my complications for a Watch face. What do I still need to do?

谢谢

推荐答案

这些代码更改是必需的:

These code changes are required:

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，您需要在扩展程序中将图像作为资产提供.

Plus you need to provide the images as assets in the extension.
