##About
I straggled for a long time about how to switch cellular use private API or some hack way,but I could not achieve.So,this workaround is no-big-deal,just one code - a URL Scheme to open Setting-Cellular page and open/close cellular manually.If you have some technology to achieve switch celluar,fell free to tell me or fork it,I think you will help a lot of people like me who want to make a little thing in life better and more convenient.Thanks indeed!
