ReactNative TextInput placeholderTextColor似乎不起作用

Question

这似乎是这么简单的事,我不明白我怎么没有得到这个权利,但placeholderTextColor在ReactNative的TextInput是不是做了我什么.

http://facebook.github.io/react-native/docs/textinput.html#placeholdertextcolor

<TextInput
    style={styles.input}
    placeholder="Foobar"
    placeholderTextColor="#FFFFFF"/>

什么也没做....

Answer 1

这工作 -

<TextInput
  placeholder="Enter password"
  placeholderTextColor="white"
/>

希望能帮助到你!干杯!

Answer 2

 <TextInput
      value={this.state.environment}
      onChangeText={(environment) => this.setState({ environment })}
      placeholder={'Environment'}
      placeholderTextColor="#202020"
      secureTextEntry={true}
      style={styles.input}
      underlineColorAndroid='rgba(0,0,0,0)'
    />
