Phone number formatting on iOS

Question

I have a text field where the user enters data. It's a phone number field. If the user enters 1234567890, I want it displayed as (123)-(456)-7890 as the user types. How is this possible?

Format (xxx) xxx-xxxx

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     int length = (int)[self getLength:textField.text];     //NSLog(@"Length  =  %d ",length);      if(length == 10)     {         if(range.length == 0)             return NO;     }      if(length == 3)     {         NSString *num = [self formatNumber:textField.text];         textField.text = [NSString stringWithFormat:@"(%@) ",num];          if(range.length > 0)             textField.text = [NSString stringWithFormat:@"%@",[num substringToIndex:3]];     }     else if(length == 6)     {         NSString *num = [self formatNumber:textField.text];         //NSLog(@"%@",[num  substringToIndex:3]);         //NSLog(@"%@",[num substringFromIndex:3]);         textField.text = [NSString stringWithFormat:@"(%@) %@-",[num  substringToIndex:3],[num substringFromIndex:3]];          if(range.length > 0)             textField.text = [NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]];     }      return YES; }  - (NSString *)formatNumber:(NSString *)mobileNumber {     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"-" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"+" withString:@""];      NSLog(@"%@", mobileNumber);      int length = (int)[mobileNumber length];     if(length > 10)     {         mobileNumber = [mobileNumber substringFromIndex: length-10];         NSLog(@"%@", mobileNumber);      }      return mobileNumber; }  - (int)getLength:(NSString *)mobileNumber {     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"-" withString:@""];     mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"+" withString:@""];      int length = (int)[mobileNumber length];      return length; }
