iOS今日扩展崩溃
我们最近在应用程序中添加了“今日”扩展 它是一个带有简单tableView的扩展,用于从我们的服务器加载数据,用Swift编写 但是,在我们的用户在线使用扩展后,我们收到了来自iOS今日扩展崩溃,ios,swift,crash,today-extension,Ios,Swift,Crash,Today Extension,我们最近在应用程序中添加了“今日”扩展 它是一个带有简单tableView的扩展,用于从我们的服务器加载数据,用Swift编写 但是,在我们的用户在线使用扩展后,我们收到了来自Crashlytics的大量崩溃数据,而且苹果也报告了相同的崩溃问题 但是,我们无法再现崩溃,甚至无法找到崩溃的原因,因为系统调用的widgetPerformUpdateWithCompletionHandler方法正在崩溃 下面是崩溃日志的详细信息,部分信息已被替换 Crashed: com.apple.main-thr

的大量崩溃数据,而且苹果也报告了相同的崩溃问题
但是,我们无法再现崩溃,甚至无法找到崩溃的原因,因为系统调用的widgetPerformUpdateWithCompletionHandler
方法正在崩溃

奇怪的是:
无法加载
)谢谢大家! 回答我自己的问题 @matt是对的,现在我只在数据获取任务完成时调用
completionHandler
,而不是总是在WidgetPerformUpdate WithCompletionHandler
方法的最后一个调用completionHandler
我再也没有遇到车祸了,问题解决了 你能在我们要崩溃的区域显示你的代码吗?嗨@matt我已经添加了widgetPerformUpdateWithCompletionHandler的代码,你能看一下吗?你不应该返回
NoData
?返回时您还没有数据,因为您的数据稍后会在后台线程中提供。(要么是这样,要么就是你在主线程上建立网络,这完全是不可能的。)@matt谢谢,我来试试。现在,仅当任务完成时才调用completionBlock。
func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)) {
// Perform any setup necessary in order to update the view.
// If an error is encountered, use NCUpdateResult.Failed
// If there's no update required, use NCUpdateResult.NoData
// If there's an update, use NCUpdateResult.NewData

self.posts = posts!.filter({ (Post) -> Bool in

}
completionHandler(NCUpdateResult.NewData)
