Extract an NSString using NSScanner

Question

I'm fetching data from AllContacts; in that data I'm getting contact details such as (998) 989-8989. Using this number, I'm not able to make a call. Can any one help out with this? Thanks in advance.

HI All

At last i have used this following code to resolve this issue

NSString *originalString = @"(998) 989-8989";
NSMutableString *strippedString = [NSMutableString 
                                   stringWithCapacity:originalString.length];

NSScanner *scanner = [NSScanner scannerWithString:originalString];
NSCharacterSet *numbers = [NSCharacterSet 
                           characterSetWithCharactersInString:@"0123456789"];

while ([scanner isAtEnd] == NO) {
    NSString *buffer;
    if ([scanner scanCharactersFromSet:numbers intoString:&buffer]) {
        [strippedString appendString:buffer];

    } else {
        [scanner setScanLocation:([scanner scanLocation] + 1)];
    }
}

NSLog(@"%@", strippedString);

Thanks All

Sounds like you can just remove spaces, brackets and hypens.

NSString *phoneNumber = @"(998) 989-8989";
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"-" withString:@""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"(" withString:@""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@")" withString:@""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@" " withString:@""];
phoneNumber = [@"tel://" stringByAppendingString:phoneNumber];
[[UIApplication sharedApplication] openURL:phoneNumber];
