You can use few methods of NSString and NSMutableString as :

NSString *phone=@"(0) 111192222-2222";
//I'm from Brazil and here the correct mask for mobile phone numbers is (01111) 92222-2222
NSMutableString *editPhone=[NSMutableString stringWithString:[phone stringByReplacingOccurrencesOfString:@")" withString:@""]];
editPhone=[NSMutableString stringWithString:[editPhone stringByReplacingOccurrencesOfString:@" " withString:@""]];

[editPhone insertString:@") " atIndex:6];


NSLog(@"%@",editPhone);//(01111) 92222-2222
