Complications on the watch face

 

watchOS2支持自定义表盘的Complication（苹果把表盘上显示的每一个控件称之为Complication）。苹果已经做使定制Complication在watchOS2的非常好的工作。WatchoOS现在包含ClockKit（表盘开发工具包），他包含了所有可定制化的Complication类型。自定义表盘的工作方式是非常简单的，只需要你的Watch Extension提供实现CLKComplicationDataSource协议，提供给ClockKit（表盘）数据。

Complication的五大分类：

一张图解释清楚：

 
 Complication 布局

提供给表盘(ClockKit)显示元素主要是通过CKComplicationTemplate，每一种家族的表盘元素 (complication)都有特定的子类，共提供用23个子类：

 通过自己的业务需求来选择数据展示所需模版。

 

Complication的Provider：

可以通过选择上面的模版来展示我们的数据。那么我们的数据如何显示在模版上的呢？我们可以通过设置模版的Providers(提供者)，Providers是非常灵活的，提供了各种各样的Provider，如需要显示文本内容，我们有CLKTextProvider，它的子类CLKSimpleTextProvider非常常用，它有个text属性，设置这个属性提供给模版显示简单的文本内容。显示图片用CLKImageProvider提供给模版显示简单图片。使用CLKDateTextProvider,CLKTimeTextProvider和relativCLKRelativeDateTextProvider来为表盘显示时间。

/1.创建选择的模版
let tmpl = CLKComplicationTemplateModularLargeStandardBody()
//2.使用Provider设置要显示的数据
tmpl.headerImageProvider = CLKImageProvider(onePieceImage:UIImage(named: "soccer_ball")!)
tmpl.headerTextProvider = CLKTimeTextProvider(date: match.date!)
tmpl.body1TextProvider = CLKSimpleTextProvider(text: match.teamDesc!)
tmpl.body2TextProvider = CLKSimpleTextProvider(text: match.groupDesc!)

 自动生成的：CLKComplicationDataSource:

@implementation ComplicationController

#pragma mark - Timeline Configuration
//时间线前后
- (void)getSupportedTimeTravelDirectionsForComplication:(CLKComplication *)complication withHandler:(void(^)(CLKComplicationTimeTravelDirections directions))handler {
    handler(CLKComplicationTimeTravelDirectionForward|CLKComplicationTimeTravelDirectionBackward);
}
//时间线起点
- (void)getTimelineStartDateForComplication:(CLKComplication *)complication withHandler:(void(^)(NSDate * __nullable date))handler {
    handler(nil);
}
//时间线终点
- (void)getTimelineEndDateForComplication:(CLKComplication *)complication withHandler:(void(^)(NSDate * __nullable date))handler {
    handler(nil);
}
//在锁屏时候是否隐藏Complication
- (void)getPrivacyBehaviorForComplication:(CLKComplication *)complication withHandler:(void(^)(CLKComplicationPrivacyBehavior privacyBehavior))handler {
    handler(CLKComplicationPrivacyBehaviorShowOnLockScreen);
}

#pragma mark - Timeline Population
//获取当前complication
- (void)getCurrentTimelineEntryForComplication:(CLKComplication *)complication withHandler:(void(^)(CLKComplicationTimelineEntry * __nullable))handler {
    // Call the handler with the current timeline entry
    handler(nil);
}
//获取limit个时间点前的complication
- (void)getTimelineEntriesForComplication:(CLKComplication *)complication beforeDate:(NSDate *)date limit:(NSUInteger)limit withHandler:(void(^)(NSArray<CLKComplicationTimelineEntry *> * __nullable entries))handler {
    // Call the handler with the timeline entries prior to the given date
    handler(nil);
}
//获取limit个时间点后的complication
- (void)getTimelineEntriesForComplication:(CLKComplication *)complication afterDate:(NSDate *)date limit:(NSUInteger)limit withHandler:(void(^)(NSArray<CLKComplicationTimelineEntry *> * __nullable entries))handler {
    // Call the handler with the timeline entries after to the given date
    handler(nil);
}

#pragma mark Update Scheduling
//多久更新时间线
- (void)getNextRequestedUpdateDateWithHandler:(void(^)(NSDate * __nullable updateDate))handler {
    // Call the handler with the date when you would next like to be given the opportunity to update your complication content
    handler(nil);
}

#pragma mark - Placeholder Templates
//complication的placeholder
- (void)getPlaceholderTemplateForComplication:(CLKComplication *)complication withHandler:(void(^)(CLKComplicationTemplate * __nullable complicationTemplate))handler {
    // This method will be called once per supported complication, and the results will be cached
    handler(nil);
}

@end
