方法有2种
1.利用UGUI中的Button来制作。
<pre name="code" class="csharp">using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System;
using System.Collections.Generic;
[Serializable]
public class TabControlEntry
{[SerializeField]private GameObject panel = null;public GameObject Panel { get { return panel; } }[SerializeField]private Button tab = null;public Button Tab { get { return tab; } }
}using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System;
using System.Collections.Generic;public class TabControl : MonoBehaviour
{[SerializeField]private List<TabControlEntry> entries = null;[SerializeField]private GameObject panelContainer = null;[SerializeField]private GameObject tabContainer = null;[SerializeField]private GameObject tabPrefab = null;[SerializeField]private GameObject panelPrefab = null;protected virtual void Start(){foreach (TabControlEntry entry in entries){AddButtonListener(entry);}if (entries.Count > 0){SelectTab(entries[0]);}}public void AddEntry(TabControlEntry entry){entries.Add(entry);}private void AddButtonListener(TabControlEntry entry){entry.Tab.onClick.AddListener(() => SelectTab(entry));}private void SelectTab(TabControlEntry selectedEntry){foreach (TabControlEntry entry in entries){bool isSelected = entry == selectedEntry;entry.Tab.interactable = !isSelected;entry.Panel.SetActive(isSelected);}}
}
2.通过Toggle来制作
可以将Toggle中的Checkmark对象看作选中的标签页，Background对象看作是未被选中是的标签显示，将几个Toggle放到一个Group中，即是一组标签。同时，UGUI的最好的一个优势就是，同一个画布上，在Hierarchy视图中，位置越靠下的越后渲染，所以，我们可以通过transform中的SetAsLastSibling()方法将选中的Toggle动态放到最下面，这样就可以让选中的Toggle靠前显示，可以做成像谷歌浏览器页面的样式。
