获取时间线后，iOS 14 小部件扩展程序崩溃

转载作者：行者123 更新时间：2023-12-03 21:10:57

我正在实现一个小部件扩展，当完成句柄被调用时它会随机崩溃。抛出异常"-[NSConcreteFileHandle fileDescriptor]: Invalid argument"这是我的实现:

func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {

    let countArticles = self.countArticles(dependingOn: context.family)

    self.backendService.fetchArticles(countArticles: countArticles) { [weak self] (result) in

        let secondsUntilNextRefresh = TimeInterval(10 * 60)
        let dateToInvokeNextRefresh = Date().addingTimeInterval(secondsUntilNextRefresh)
        let timelineEntries = TimelineMapper().mapArticlesResultToTimelineEntry(result)
        let timeline = Timeline(entries: timelineEntries,
                                policy: .after(dateToInvokeNextRefresh))

        DispatchQueue.main.async {

            completion(timeline)
        }
    }
}

和堆栈跟踪
