SwiftUI Widget IntentConfigurati

首先，Widget 分为StaticConfiguration和IntentConfiguration，一个静态、长按不可编辑，一个是长按可编辑

这里要讲的是IntentConfiguration

• 创建widget时，勾选Intent
• 创建widget时，不勾选Intent，直接在后期手动撸
  ps: 前者没什么讲的，直接撸怎么在后期 手动撸一个IntentConfiguration

一、创建Intent文件

• New File 选择 Siri Intent Definition File，在创建的时候，要注意Targets的勾选，要给谁用，就要勾选谁，不只是项目Target，还要勾选对应的小组件Target

• 添加Intents,命名最好跟刚创建的 Siri Intent Definition File文件一致，便于记忆和读
  

  intent

二、修改默认代码

• 先修改Widget的配置，StaticConfiguration改成IntentConfiguration

@main
struct XG_Widget: Widget {
    let kind: String = "XG_Widget"

    var body: some WidgetConfiguration {
        IntentConfiguration(kind: kind, intent: MyCustomIntentsIntent.self, provider: Provider()) { entry in
            XG_WidgetEntryView(entry: entry)
        }
        .configurationDisplayName("XG_SwiftUI_3Day")
        .description("这是一个测试的widget.")
    }
}

同理修改其他代码为:

struct Provider: IntentTimelineProvider {
    typealias Entry = SimpleEntry
    
    typealias Intent = MyCustomIntentsIntent
    
    
    func placeholder(in context: Context) -> SimpleEntry {
        SimpleEntry(date: Date())
    }

    func getSnapshot(for configuration: Intent, in context: Context, completion: @escaping (SimpleEntry) -> Void) {
        let entry = SimpleEntry(date: Date())
        completion(entry)
    }

    func getTimeline(for configuration: Intent, in context: Context, completion: @escaping (Timeline<SimpleEntry>) -> Void) {
        var entries: [SimpleEntry] = []

        // Generate a timeline consisting of five entries an hour apart, starting from the current date.
        let currentDate = Date()
        for hourOffset in 0 ..< 5 {
            let entryDate = Calendar.current.date(byAdding: .hour, value: hourOffset, to: currentDate)!
            let entry = SimpleEntry(date: entryDate)
            entries.append(entry)
        }

        let timeline = Timeline(entries: entries, policy: .atEnd)
        completion(timeline)
    }
}

至此，添加小组件后，长按会出现可编辑按钮
