UGUI制作Tab标签页

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。
