How is the screen of Apple mobile phone fixed horizontally or vertically?

At present, Apple's mobile phone can only be fixed as vertical screen, and many interfaces do not support horizontal screen display.

Fix method for vertical screen:

Enter the control center (press and hold the bottom of the screen and move your finger up to open the control center; Open the control center through the iphone auxiliary button on the screen)

After entering the control center, click the small lock icon in the shortcut switch:

① The icon lights up to indicate that the screen is locked. At this time, the screen will not rotate when the phone rotates.

② When the icon is not lit, it means that the screen is not locked. At this time, when the phone turns, the screen will rotate (not all interfaces can turn, such as WeChat interface).
