问题描述

我正在实现BackgroundTasks框架来更新数据.但是我遇到了以下问题

I am implementing BackgroundTasks Framework for updating the data. But I got the below issue

Could not schedule refreshApp: Error Domain=BGTaskSchedulerErrorDomain Code=1 "(null)"
Could not schedule data featch: Error Domain=BGTaskSchedulerErrorDomain Code=1 "(null)"
2019-10-01 19:19:32.550320+0530 SOBackgroundTask[34131:1129470] Can't end BackgroundTask: no background task exists with identifier 3 (0x3), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.

推荐答案

解决方案是在设备上运行.我在模拟器上运行.但是，这表明在模拟器上运行时，已在设置"中启用了后台应用刷新".

The solution is to run on a device. I was running on simulator. However, It was showing Background App Refresh has been enable in Settings while running on simulator.
