我目前正在为watchOS 2应用程序设置复杂功能.
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.
