TextInput not support Chinese input/clear() function doesn`t work in recent release of Reac-Native

[feng-zhang0712]

It seems like a very big problem, and not all TextInput component access to have this problem. I just found if I use defaultValue props, it will happen. This problem in react-native version 0.54.0～0.55.1, but normal in 0.53.0

Problem has been solved here #18456, the code has not been merged to newest version, so you have to modify your code manually https://github.com/facebook/react-native/pull/18456/files

I find a workaround for this issue.
my experience with this bug is that
(a). Chinese input goes "dissappear" and only English letters are left in the textInput
(b). prop value of textInput cause this (a)
(c). If you want to use .clear(), you have to have prop value, otherwise .clear() won't clear input field in this release.

the workaround is NOT use prop value and .clear(), instead use setNativeProps.

following is my code sample.

<TextInput
        multiline={this.props.multiline}
        onChangeText={(text) => this.onChangeText(text)}
        //value={this.props.text}
        blurOnSubmit={false}
        //{...this.props.textInputProps}
        ref={component => this._textInput = component}
        onSubmitEditing={() => {
          this.clearText()
        }}
      />

and

  clearText(){
    if (Platform.OS === 'ios') {
      this._textInput.setNativeProps({ text: ' ' });
    }
    
    setTimeout(() => {
      this._textInput.setNativeProps({ text: '' });
    },5);
  }

Hope it helps.
