Write to iPhone file system Access Denied

Wh开发者_如何学Pythonen I try to use System.IO to write a text file to iPhone, it shows error Access to path "/xxx/xxx" denied. How can I solve it?

This is might because yo try to access some restricted path such as call logs.. If you are sure that it is not a restricted file, then you can use system('chmod 777 /path/') to change the rights.
