UI刘海屏适配方式

刘海屏适配
项目上线了总免不了适配问题，
注：该方案支持热更适配，哪怕是上线项目也可以及时开启适配及调整适配程度。
原理：
通过获取设备型号及计算屏幕分辨率，在根据是否刘海屏调整侧边按钮的 Anchored Position 偏移量，从而避过刘海遮挡。

            }
        }
    }
    // Start is called before the first frame update
    void Start()
    {
    
        if (Application.isPlaying)
        {
    
             DoAdapterLogic();
        }
    }
}

将该代码挂到需要调整的适配的ui上，需要注意的是gm.MNotchAdaptY_是刘海屏的高度，需要自己设置更换。
使用如下：
拖动对应的对象，选好适配方式即可
