Try this

NSString *numberString = [[mixedString componentsSeparatedByCharactersInSet:
                [[NSCharacterSet decimalDigitCharacterSet] invertedSet]] 
                componentsJoinedByString:@""];

It will give digits from a string.

in case if number formatting is not what is expected, you can always use stringByReplacingOccurrencesOfString as seen in following link http://stackoverflow.com/questions/6638623/uiviewcontentmodescaleaspectfill-not-clipping – Deepak Thakur May 31 '16 at 06:30

stringByReplacingOccurrencesOfString supports also regular expression

NSString *phoneNumber = @"(123)-(456)-7890";
NSString *filteredPhoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"[ ()-]" 
                                 withString:@""
                                    options:NSRegularExpressionSearch 
                                      range:NSMakeRange(0, phoneNumber.length)];
NSLog(@"%@", filteredPhoneNumber);

Put all characters to be ignored between the brackets in the first parameter.

An alternative regex is @"[^\\d+]" which means ignore all non-digit characters

NSString *str = @"(123)-(456)-7890";
str = [str stringByReplacingOccurrencesOfString: @"(" withString:@""];
str = [str stringByReplacingOccurrencesOfString: @")" withString:@""];
str = [str stringByReplacingOccurrencesOfString: @"-" withString:@""];
NSLog(@"Output = %@",str);

Output = 1234567890

You also replacing more character in Single Line of coding using stringByReplacingOccurrencesOfString

NSString *YourString = @"(123)-(456)-7890";
YourString = [[[YourString stringByReplacingOccurrencesOfString:@"(" withString:@""] stringByReplacingOccurrencesOfString:@")" withString:@""] stringByReplacingOccurrencesOfString:@"-" withString:@""];
NSLog(@"YourString == > %@",YourString);

YourString == > 1234567890

Use this code,

NSString *valString = @"(123)456-7890";

NSString* phoneStr=[[[valString stringByReplacingOccurrencesOfString:@"(" withString:@""] stringByReplacingOccurrencesOfString:@")" withString:@""] stringByReplacingOccurrencesOfString:@"-" withString:@""];

NSLog(@"phone String %@",phoneStr); // finally you get phone String 1234567890

its working for me, hope its helpful

If you want your code to work outside the USA, use Google's telephony library. Formatting and extracting phone numbers is difficult. I wouldn't even try doing it myself by hand.
