Question

我目前正在为watchOS 2应用程序设置并发症。

我想提供三种不同类型的并发症：

功利小“
模块化小作品
圆形小

所有这些复杂类型应该只是将我的应用程序图标显示为图像。在我的ClockKit类中，我实现了以下方法：

func getCurrentTimelineEntryForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTimelineEntry?) -> Void) {

    if complication.family == .CircularSmall {

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

    } else if complication.family == .UtilitarianSmall{

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

    } else if complication.family == .ModularSmall {

        let template = CLKComplicationTemplateModularSmallRingImage()
        template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "app_icon")!)
        let timelineEntry = CLKComplicationTimelineEntry(date: NSDate(), complicationTemplate: template)
        handler(timelineEntry)

    } else {

        handler(nil)

    }

}

我不确定这是实现我的想法的恰当方式，所以我想知道将图像显示为我的复杂功能的代码。有谁知道我怎么能做到这一点？

首先，我强烈建议您观看有关并发症的Apple's session，除非您还没有看到它。

您需要至少在CLKComplicationDataSource中实施以下ComplicationController的非可选方法：

public func getSupportedTimeTravelDirectionsForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTimeTravelDirections) -> Void)
public func getCurrentTimelineEntryForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTimelineEntry?) -> Void)
public func getPlaceholderTemplateForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTemplate?) -> Void)

所有其他方法都是可选的。据你所知，你只实现了第二个。其余两个的实现可能在您的上下文中如下：

class ComplicationController: NSObject, CLKComplicationDataSource {

    func getSupportedTimeTravelDirectionsForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTimeTravelDirections) -> Void) { 
        // Turn off time travelling
        handler([CLKComplicationTimeTravelDirections.None])
    }

    func getPlaceholderTemplateForComplication(complication: CLKComplication, withHandler handler: (CLKComplicationTemplate?) -> Void) {
        var template: CLKComplicationTemplate?

        switch complication.family {
            case .CircularSmall:
                template = CLKComplicationTemplateCircularSmallRingImage()
                template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "app_icon")!)
            case .UtilitarianSmall:
                template = CLKComplicationTemplateUtilitarianSmallRingImage()
                template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "app_icon")!)
            case .ModularSmall:
                template = CLKComplicationTemplateModularSmallRingImage()
                template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "app_icon")!)
            case .ModularLarge:
                template = nil
            case .UtilitarianLarge:
                template = nil
        }

        handler(template)
    }

}

并且不要忘记将复杂配置中的数据源类指定为$(PRODUCT_MODULE_NAME).ComplicationController并选中相应的复选框。

这是您案例中最小的并发症配置。
