我們已經添加了今天的擴展到我們的應用程序最近。iOS今日擴展崩潰
它是一個帶有簡單tableView的擴展,用於從我們的服務器加載數據,使用Swift編寫。
但是擴展程序在用戶在線後,我們收到了很多來自Crashlytics
的崩潰數據,Apple也報告了相同的崩潰問題。
但是,我們無法重現崩潰,甚至找不到崩潰的原因,因爲系統正在調用widgetPerformUpdateWithCompletionHandler
方法。
下面是崩潰日誌的細節,一些信息被替換。

奇怪的代碼是:
,而我們通常使用我們的今天,擴展大家有沒有遇到崩潰的問題(這如果今天擴展崩潰應該顯示
Unable to load
)我們沒有收到用戶報告今天的分機無法使用的任何問題。
我們在我們的設備上發現了相同的崩潰日誌,但今天的分機正常工作,如
1.
所述。而且,記錄崩潰日誌的時間,我沒有使用我的手機!
所以我們猜測這是一個「假」碰撞,碰撞記錄了,但擴展沒有真正崩潰。
有沒有人面臨同樣的問題? 謝謝!
你能在我們崩潰的地區顯示你的代碼嗎? – matt
Hi @matt我已經添加了widgetPerformUpdateWithCompletionHandler的代碼,請你看一下嗎? – Johnny
你不應該返回'NoData'嗎?您在返回時還沒有數據,因爲您的數據稍後會在後臺線程中提供。 (或者你或者在主線程中聯網,這是一個總的禁止號碼。) – matt
