Using string literals in ref att

eslint报错问题

<TextInput
              style={styles.textInputStyle}
              underlineColorAndroid="transparent"
              keyboardType="numeric"
              maxLength={11}
              placeholder="请输入收到的验证码"
              placeholderTextColor="#cccccc"
              onChangeText={text => this.setState({ msgCode: text })}
              ref="MsgCode"
            />

正确格式为下面 用到refs属性时，比如：直接this.MsgCode.blur()

   <TextInput
              style={styles.textInputStyle}
              underlineColorAndroid="transparent"
              keyboardType="numeric"
              maxLength={11}
              placeholder="请输入收到的验证码"
              placeholderTextColor="#cccccc"
              onChangeText={text => this.setState({ msgCode: text })}
              ref={(c) => { this.MsgCode = c; }}
            />
