swift - WidgetKit 未更新

Question

例如，我希望我的小部件每 5 秒更新一次。我不知道为什么它不起作用。代码应该是正确的。

更新代码：

func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
        var entries: [SimpleEntry] = []
        
        let currentDate = Date()
        for _ in 0 ..< 5 {
            let entryDate = Calendar.current.date(byAdding: .minute, value: 60, to: currentDate)!
            let entry = SimpleEntry(date: entryDate, configuration: configuration, clubname: networkManager.clubName)
            entries.append(entry)
        }
        
        let timeline = Timeline(entries: entries, policy: .atEnd)
        completion(timeline)
    }

因为您添加了相同的条目。如果您像下面的示例更改值，它将被刷新。

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

    // Generate a timeline consisting of five entries an hour apart, starting from the current date.
    let currentDate = Date()
    let chapter = getChapterWith(level: "1") // it is returned a array.
    for index in 0 ..< chapter.count {
        let entryDate = Calendar.current.date(byAdding: .second, value: index, to: currentDate)!
        let entry = SimpleEntry(date: entryDate, chapter: chapter[index])
        entries.append(entry)
    }

    let timelineDate = Calendar.current.date(byAdding: .second, value: 1, to: Date())!
    let timeline = Timeline<SimpleEntry>(entries: entries, policy: .after(timelineDate))
    completion(timeline)
}

func getChapterWith(level: String) -> [Chapter] {
    return []
}

//Chapter是一个struct，它是SimpleEntry中的一个变量。

struct SimpleEntry: TimelineEntry {
    let date: Date
    let chapter: Chapter
}
