点击输入字段时如何禁用文本突出显示？

Question

我知道之前有人问过这个问题，但 none 的解决方案似乎适用于移动设备。我发现的解决方案在我的 PC 上运行良好，但不幸的是在我的平板电脑上运行不佳。我对解决方案发表了评论，看看他们是否可以提供帮助，但似乎他们已经一年多没有使用 SO 了。因此，我在这里试试运气，看看是否有人知道如何让他们的解决方案在移动设备上运行？

这是我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class TextFieldBehaviour : MonoBehaviour, ISelectHandler
{
    private InputField inputField;
    private bool isCaretPositionReset = false;

    void Start()
    { 
        inputField = gameObject.GetComponent<InputField>();

    }

    public void OnSelect(BaseEventData eventData)
    {
         StartCoroutine(disableHighlight());
    }


    IEnumerator disableHighlight()
    {
        Debug.Log("Selected!");

        //Get original selection color
        Color originalTextColor = inputField.selectionColor;
        //Remove alpha
        originalTextColor.a = 0f;

        //Apply new selection color without alpha
        inputField.selectionColor = originalTextColor;

        //Wait one Frame(MUST DO THIS!)
        yield return null;

        //Change the caret pos to the end of the text
        inputField.caretPosition = inputField.text.Length;

        //Return alpha
        originalTextColor.a = 1f;

        //Apply new selection color with alpha
        inputField.selectionColor = originalTextColor;

        if (inputField.touchScreenKeyboard.canSetSelection)
            inputField.touchScreenKeyboard.selection = new RangeInt(0, 0);
    }
}

如果您正在撰写有关本机屏幕键盘的文章，您可以尝试 this:

if (inputField.touchScreenKeyboard != null && inputField.touchScreenKeyboard.active && inputField.touchScreenKeyboard.canSetSelection)
    inputField.touchScreenKeyboard.selection = new RangeInt(0, 0);

RangeInt的参数为选区的起始位置和长度；

请记住，并非所有平台都支持此功能。有关 TouchScreenKeyboard 的所有功能，请参阅文档 here and here。
