Unity vertical screen packaging, dynamically switch to horizontal screen

Problem Description

Since our main application is a vertical screen application, the packaging rotation method can only be Portrait;
and some functional modules need to be displayed on a horizontal screen. At this time, it is necessary to dynamically switch to a horizontal screen. After exiting the module, switch back to the vertical screen;

In fact 旋转相机, it can be done, but it will be a headache when adapting the UI 不推荐.

solution:

Unity allows switching between horizontal and vertical screens at runtime, as follows:

/// <summary>
/// 切换为横屏
/// </summary>
private void SetOrientationLandscape()
{
    
    
    //设置横屏
    Screen.orientation = ScreenOrientation.Landscape;
    //设置横屏画布标准分辨率，保证UI横竖屏一致
    scaler.referenceResolution = new Vector2(1920, 1080);
    //这个match比例一般情况是这样，可根据项目情况设置
    scaler.matchWidthOrHeight = 1;
}

/// <summary>
/// 切换为竖屏
/// </summary>
public void SetOrientationPortrait()
{
    
    
    //设置竖屏
    Screen.orientation = ScreenOrientation.Portrait;
    //设置竖屏画布标准分辨率
    scaler.referenceResolution = new Vector2(1080, 1920);
    scaler.matchWidthOrHeight = 0;
}
