Unity项目显示手机系统顶部通知栏
最近在做这一个功能，因为没有使用Android studio进行打包，所以寻找其他办法。
再此介绍不需要其他操作即可的办法；
Android：
1、直接在C#中调用
有个缺陷，这个方法只能适配部分机型，其他机型不能适配
代码如下：
private static int newStatusBarValue;
/// ·
2、可以调节是否仅显示电量和时间、还有部分类型
测试发现，骁龙处理器的机型，只显示电量。具体问题还未查清，有知道的朋友麻烦告知。
通过代码控制：
代码如下：
public class AndroidStatusBar
{
//当AndroidStatusBar.dimmed=false时，状态栏显示所有状态及通知图标；true时，状态栏仅电量和时间，不显示其他状态及通知
public enum States
{
Unknown,
Visible, //显示状态栏，占用屏幕最上方的一部分像素
VisibleOverContent, //悬浮显示状态栏，不占用屏幕像素
TranslucentOverContent, //透明悬浮显示状态栏，不占用屏幕像素
Hidden, //隐藏状态栏
}
// Constants
private const uint DEFAULT_BACKGROUND_COLOR = 0xff000000;

使用代码：
if (Application.platform == RuntimePlatform.Android)
{
AndroidStatusBar.dimmed = false;
AndroidStatusBar.statusBarState = AndroidStatusBar.States.TranslucentOverContent;
}
直接修改 AndroidStatusBar.statusBarState即可。
通过后面的测试，大部分机型都能适用，前文说的骁龙处理器的机型，是因为dimmed的值为true，其他机型对这个值的改变对状态栏没有影响。应该是没有找对值。在调用的时候将其设置为false即可全部显示。
IOS
在Unity编辑器下，打开playerSettings
将 statusBar Hidden 取消勾选，Default模式对应透明底部（Translucent Over Content）
