The iOS TravelCalc has had an update with version V1.1 recently. I’ll prepare another article to describe the details about this update. Today I’d like to focus on the crash problem of this version on iPad in landscape mode.
From the analysis data been received by now, there has been over 20 users affected by this issue. The symptom is crash after launch of TravelCalc on iPad under landscape mode. This issue will affect all iPads with iOS 13.0 and up.
The root cause of this issue is some code fragments changed for supporting “Dark Mode” after iOS 13. When use change the appearance mode, TravelCalc should change its own display mode and set the correct color code to each related component. To accomplish this, some new code fragments should be added to a rarely used event location. Under landscape mode of iPad, this action will make a component in TravelCalc disappear and appear again after the change of appearance mode . During this period any attempt to co-work with this component will lead to CRASH.
How to resolve it?
To solve this issue, an updated version of TravelCalc with version number V1.1.1 will be submitted to Apple for review. Once approved, users will be able to update to this version and cease this problem. The planned schedule for this patch will be within this week, before 6/20, 2020.
There is a workaround of this issue before the patched version. You may set iPad in “Portrait Mode” before launching TravelCalc. The App will lock the direction of screen into Portrait Mode after successful launch.
Sorry for any inconvenience that may cause to iPad users. The patch is on the way. I’ll send it to Apple for review once the package is ready.
May peace and all blessings be with you during this worldwide pandemic.
