Use special input methods on iPhone
On iPhone, you can use special keyboards, your finger, or a stylus to enter some languages in different ways. A few examples are Chinese Cangjie and Wubihua, Japanese Kana, and Facemarks. You can also use your finger or a stylus to write Chinese characters on the screen.
Build Chinese characters from the component Cangjie keys
As you type, suggested characters appear.
To choose a character, type it, or continue typing up to five components to see more options.
Build Chinese Wubihua (stroke) characters
Use the keypad to build Chinese characters using up to five strokes, in the correct writing sequence: horizontal, vertical, left falling, right falling, and hook.
For example, the Chinese character 圈 (circle) should begin with the vertical stroke 丨.
Do any of the following:
As you type, suggested Chinese characters appear (the most commonly used characters appear first). Tap a character to choose it.
If you’re not sure of the correct stroke, enter an asterisk (*). To see more character options, type another stroke, or scroll through the character list.
Tap the match key (匹配) to show only characters that match exactly what you typed.
You can type some complex characters, such as 鱲 (part of the name for the Hong Kong International Airport), by writing two or more component characters in sequence. Tap the character to replace the characters you typed. Roman characters are also recognized.
Write Chinese characters
Write Chinese characters directly on the screen with your finger when Simplified or Traditional Chinese handwriting input is turned on.
Press a little deeper as you write to increase the line width of your character strokes (on models with 3D Touch).
As you write character strokes, iPhone recognizes them and shows matching characters in a list, with the closest match at the top. When you choose a character, its likely follow-on characters appear in the list as additional choices.
