你应该是竖着用手机看的效果，demo里的重力感应是以平放手机时为基准点控制的，待我有空可以添加竖着和横着的兼容，你可以先试着改改
多角度找基准点拍完再合成一张那肯定是最好的
you can set `alert.cancelButtonOffsetY=20;`
You can change storyboard viewcontroller's custom class,use 'sharedSliderController' method do.
You may have no problem executing your instructions on Linux, but use VS2019 on windows. I suggest cmake adding `-G "Visual Studio 16 2019"` and open `.sln` compiling with VS2019
