objective-c - 在objective-c中拆分电话号码

Question

我需要格式为 05XXXXXXXX 的拆分电话号码并放在“-”之间，例如 05X-XXXXXXX 我只需要在区号和自己编号之间放“-”号

我怎么能这样做？

Answer 1

如果您确定需要-始终排在第四位，则可以这样做

NSString *yourPhoneString=@"05XXXXXXXX";
NSMutableString *phoneNumber = [NSMutableString stringWithString:yourPhoneString];
[phoneNumber insertString:@"-" atIndex:3];
