Unity实现在Android或IOS端点击【InputField】输入框弹出键盘上的内容默认处于选中状态

最终效果如：
上代码

using UnityEngine.EventSystems;

/// <summary>
/// 该脚本挂在InputField上
/// </summary>
public class Test : MonoBehaviour, IPointerClickHandler
{
    private InputField inputField;
    private bool isClick;

    private void Awake()
    {
        inputField = GetComponent<InputField>();

        inputField.onEndEdit.AddListener(content => isClick = false);
    }

    private void LateUpdate()
    {
        if (isClick)
            inputField.touchScreenKeyboard.selection = new RangeInt(0, inputField.touchScreenKeyboard.text.Length);
    }

    public void OnPointerClick(PointerEventData eventData)
    {
        isClick = true;
    }
}

以上代码即可实现该功能，目前能想到的方法就只有这一种，有更好办法的大佬欢迎指正
