调研方向

Start by reading the iOS date picker code that handles timeZoneName, minimumDate, and the visible calendar month; the issue does not name specific files or tests. Reproduce on iOS with datetime mode, a time zone ahead of the device, the date set to the first of the month, and minimumDate set to today. Done means the picker opens without crashing and respects both the configured time zone and minimum date.

描述

Bug report

Summary

On iOS, with mode="datetime", set timeZoneName to a zone that's ahead of you. Say for instance that your phone is set to London time, you can hardcode this setting to Paris time (one hour ahead).
Then, set the the current date on your device to the first of the month, for instance any time on December 1st.

Also provide a minimumDate that can be today's date.

You'll now see a crash when you open the datepicker, saying "Exception thrown while executing UI block: Unable to set a visible month that is before the minimum or after the maximum date.

Reproducible sample code

Steps to reproduce

  1. On iOS, with mode="datetime", set timeZoneName to a zone that's ahead of you. Say for instance that your phone is set to London time, you can hardcode this setting to Paris time (one hour ahead).
  2. Then, set the the current date on your device to the first of the month, for instance any time on December 1st.
  3. Also provide a minimumDate that can be today's date.
  4. You'll now see a crash when you open the datepicker, saying "Exception thrown while executing UI block: Unable to set a visible month that is before the minimum or after the maximum date.
    _44-IRCTUIManager"

Describe what you expected to happen:

  1. The calendar should have been acting like the device is in the timezone according to the provided timeZoneName
  2. And minimumDate should still be respected, without crashing.
