效果图

前言

PlayerPrefsKey现在其实用得并不多，不过也有一些应用场景。

最近开发过程中，发现要删除一个PlayerPrefsKey,有点麻烦。可以写代码删除或者去注册表删除。都是都感觉有点麻烦，而且也没法知道当前已经设置了哪些PlayerPrefsKey。所以就想做一个窗口来查看当前所有key，并可以支持搜索和删除。

tip:修改功能就不添加了，因为一般删除PlayerPrefsKey让其恢复默认值是安全OK的。但是如果直接不知道它的用处或值域，直接修改，就可能有问题。所以不增加修改功能。

开发

开发分两步：

第一步获取所有PlayerPrefsKey数据；
第二步根据数据写编辑器窗口；

一、获取数据

获取数据我是直接在网上搜了一下获取方法，找到了这篇博客，获取所有PlayerPrefsKey windows下测试可以拿到所有key. 获取数据可以直接看这个链接。这里我们主要讲一下编辑器窗口。

目录结构

看文章可以知道需要两个工具类: PlayerPrefsExtension.cs 和 Plist.cs.
目录结构如下，包含上面两个工具类，和窗口编辑器PlayerPrefsWindow。工具类代码会在最后提供

二、开发编辑器窗口

效果图

思路

看效果图，可以知道大体分为两部分：最上面的搜索栏和下面的主框体。
怎么实现搜索呢：

首先，我们可以通过工具类获取到所有的key
如果搜索框是空的，我们就把所有数据交给主框体渲染；
如果搜索框有数据，我们就把第一步拿到的数据过滤一下，再交给主框体渲染。这样就可以了。

一、绘制搜索栏

    private void DrawSearchBar(){//绘制label:GUIStyle labelStyle = new GUIStyle(EditorStyles.boldLabel);labelStyle.normal.textColor = Color.cyan;EditorGUILayout.LabelField("输入要搜索的key:",labelStyle,GUILayout.Width(120));//绘制输入框:var style = new GUIStyle(EditorStyles.textField);style.fontStyle = FontStyle.Bold;searchKey = GUILayout.TextField(searchKey,style,GUILayout.ExpandWidth(true));//绘制 清空输入 按钮if (GUILayout.Button("x",btnWidthOpt)){searchKey = string.Empty;}//绘制 删除所有Key 按钮if (GUILayout.Button("删除所有",btnWidthOpt)){if (EditorUtility.DisplayDialog("删除提示", "确认删除所有key吗？", "确定", "取消")){PlayerPrefs.DeleteAll();};}}

二、定义PlayerPrefs数据结构体

我们用这个结构体来描述每一个PlayerPrefs

[Serializable]
public struct PlayerPrefPair
{public string Key { get; set; }public object Value { get; set; }
}

三、根据搜索框过滤数据

searchKey就是搜索框输入的内容，如果有输入，我们就过滤数据

 private void FillDataList(ref List<PlayerPrefPair> list){list.Clear();list = PlayerPrefsExtension.GetAll().ToList();if (!string.IsNullOrEmpty(searchKey)){for (int i = 0; i < list.Count; i++){if (!list[i].Key.ToLower().Contains(searchKey.ToLower())){list.RemoveAt(i);i--;}}}}

四、绘制主框体

因为内容有可能超过窗口，所以这里用了ScrollView,当内容超出时，可以滑动窗口

    private void DrawMainWindow(List<PlayerPrefPair> dataList){Rect rect = new Rect(0,searchBarHeight + 10,position.width,position.height);GUILayout.BeginArea(rect);scrollViewPos = GUILayout.BeginScrollView(scrollViewPos,false,true,GUILayout.Height(1000));GUILayout.BeginVertical();foreach (PlayerPrefPair pair in dataList){if (!PlayerPrefs.HasKey(pair.Key)){continue;}GUILayout.BeginHorizontal();    EditorGUILayout.TextField(pair.Key+":",pair.Value.ToString());GUILayout.ExpandWidth(true);if (GUILayout.Button("删除Key",btnWidthOpt)){if (PlayerPrefs.HasKey(pair.Key)){PlayerPrefs.DeleteKey(pair.Key);Debug.Log($"{GetType()} delete key success,key:{pair.Key}");}}GUILayout.EndHorizontal();}GUILayout.EndVertical();GUILayout.EndScrollView();GUILayout.EndArea();}
