如何检查InputField上的文本是否被遮挡

using UnityEngine;
using UnityEngine.UI;

public class CheckInputFieldText : MonoBehaviour
{
    public InputField inputField;

    private void Update()
    {
        // 获取InputField的RectTransform组件
        RectTransform inputFieldRectTransform = inputField.GetComponent<RectTransform>();

        // 获取InputField的文本内容
        string text = inputField.text;

        // 获取InputField的显示区域
        Vector2 inputFieldPosition = inputFieldRectTransform.position;
        Vector2 inputFieldSize = inputFieldRectTransform.sizeDelta;
        Rect inputFieldRect = new Rect(inputFieldPosition.x, inputFieldPosition.y, inputFieldSize.x, inputFieldSize.y);

        // 检查文本是否被遮挡
        bool isTextOverflow = IsTextOverflow(text, inputFieldRect);

        // 输出结果
        if (isTextOverflow)
        {
            Debug.Log("文本被遮挡");
        }
        else
        {
            Debug.Log("文本未被遮挡");
        }
    }

    private bool IsTextOverflow(string text, Rect inputFieldRect)
    {
        // 使用GUIStyle计算文本的宽度
        GUIStyle guiStyle = new GUIStyle(GUI.skin.textField);
        float textWidth = guiStyle.CalcSize(new GUIContent(text)).x;

        // 判断文本宽度是否超出显示区域的宽度
        return textWidth > inputFieldRect.width;
    }
}
