I am not a morning person. So when I wake up, I get the message "Good Morning" on my iPhone when I wake up. If you feel the morning greeting the same way, you can easily prevent the greeting from appearing on the lock screen. This also applies if your "good morning" is actually "good day" or "good evening".
Apple has introduced the lock screen greeting, which also includes a weather widget, with the release of iOS 12. Apart from a brief appearance in an iOS 12 announcement video (see the 45-minute mark), the company did not really have that However, this talk is a full login and a side effect of another feature in iOS 1
The lock screen will only be displayed as the first time you check your iPhone after the non-fault time has expired. That is, the next time you wake up, the message is gone. Even if you stay up late, if you see the message and close the current lock screen in some way – he falls asleep, go to review apps, etc. – the greeting will not reappear until the next day if you're not bothered with bedtime ,
If you do not like how fleeting this thing is (maybe you just want a more durable weather widget on the lock screen without greeting), disabling it is easy. Just do not disturb with the bedtime mode. Open the Settings app, tap "Do not disturb" and then turn off "Bedtime". You can still use the Do Not Disturb feature without sleeping time enabled to ensure that you have a good night's sleep. You just will not wake up to a healthy welcome from your iPhone.
Note that in addition to the Welcome Screen Limit, Bedtime Mode also dims the display (see examples below), and notifications are immediately forwarded to the Notification Center. If you disable Bedtime Mode, these features will also be turned off for Do Not Disturb, even if calls and notifications are mute as usual.
