React native：TextInput 占位符未显示在 IOS 上

Question

I have a react-native component which has a TextInput. On android, the placeholder shows up with no problem, however, on IOS, it does not show up. Below I have attached a picture of the problem, as well as the code for the text input.

IOS TextInput Not showing placeholder

<TextInput
        style={{
          backgroundColor:"white",
    height: 40,
    margin: 12,
    borderWidth: 1,
    borderBottomColor: '#ffffff',
    borderTopColor: '#ffffff',
    borderRightColor: '#ffffff',
    borderLeftColor: '#ffffff',
    padding: 10,
    borderColor: "#ffffff",
    width:"70%",
    position:"absolute",
    top:80,
    borderRadius:10
  }}
        placeholder="Search"
        onChangeText={txtHandler}
        defaultValue={text}
      ></TextInput>

Answer 1

发现它出现了，我需要将此属性添加到 TextInput：

placeholderTextColor="black"
