我想提供三种不同类型的并发症：

>功利小
>模块化小物品
>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合适方式,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？

起初我强烈建议你观看 Apple’s session关于并发症,除非你还没有看到它.

您至少需要在ComplicationController中实现3个以下非可选的CLKComplicationDataSource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.在您的上下文中,剩余两个的实现可能如下：

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)    }}

不要忘记在Complication Configuration中将您的数据源类指定为$(PRODUCT_MODulE_name).ComplicationController并选中相应的复选框.

这是您案例中最小的复杂配置.
