Hey guys! I got one new way to solve this problem! It is not necessary to buy CCK and audio charge cable. IOS 13 allow us to connect the docking stations! Yes what we need is just one simple lightning docking with both lightning charge port and USB port. Here in china, this device just cost me less than 10$ and perfectly SOLVED this problem!
But you need to connect the lightning charge cable will you play! Although, it will be a little inconvenient, but this docking is useful.
Hope this message will help you!
