在objective-c中拆分电话号码

Question

我需要分辨电话号码，格式为05XXXXXXXX 并放在“ - ”之间 05X-XXXXXXX 我只需要在区号和号码之间加上“ - ”符号

我怎么能这样做？

Answer 1

如果您确定需要将-始终放在第4位，您可以这样做

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