Question

I have a string like @"[phone]" or @"256-435-81-15". I need only the digits (this is a phone number). Is this possible? I haven’t found an NSString method to do that.

Answer 1

I think there is much simpler way:

-(NSString*)getNumbersFromString:(NSString*)String{
    NSArray* Array = [String componentsSeparatedByCharactersInSet:
                      [[NSCharacterSet decimalDigitCharacterSet] invertedSet]];
    NSString* returnString = [Array componentsJoinedByString:@""];

    return (returnString);

}
