Better way to get the user's name from device?

Question

I made a function that extracts a user name from the device name.

The idea is to skip setup steps to allow the user to go straight to play

Answer 1

NSString *dname=[[UIDevice currentDevice] name];
dname=[dname componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"'的"]][0];
