Full-angle and Half-angle Switching of Apple Input Method

Taking iPhone 13 and iOS 15. 1 systems as examples, the specific methods for switching full-angle and half-angle input methods of Apple mobile phones are as follows:

Call out input method

First, open the Apple mobile phone, enter the interface that needs to input text, such as SMS or WeChat, and call up your own input method.

Click the symbol key.

Then click the "symbol" button in the lower left corner.

Toggle full and half angles.

The "Full/Half" in the lower right corner of the keyboard is a full-angle and half-angle switching key, which can be switched to each other after clicking.

Half-angle is an ASCII coding table program. Computers first started in English-speaking countries. With 26 letters and punctuation marks, the 256-bit ascll program can be run, so it is only half a corner at first, and each ordinary character only takes up one byte. However, the font size of pictographic languages such as Chinese characters, Japanese and Korean is much larger than 256, so two bytes are used to store them, that is, full width.

Chinese characters, full-width English characters, graphic symbols and special characters in GB23 12-80 are all full-width characters. General system commands do not use full-width characters, but only use full-width characters when doing word processing.

This answer applies to most of Apple's mobile phone models.
