Creating Data Detector Instances

+ dataDetectorWithTypes:error:

Creates and returns a new data detector instance.

Example

NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypeAddress | NSTextCheckingTypePhoneNumber | NSTextCheckingTypeLink error:nil];
NSString *myStr = @"(001) 1234-5678 No 1 Central Street. http//eezytutorials.com";
[detector enumerateMatchesInString:myStr options:kNilOptions range:NSMakeRange(0, [myStr length]) usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {
    NSLog(@"Values: %@", result);
}];

Output

2014-04-09 06:21:14.538 iOS-Tutorial[3703:a0b] Values: {0, 15}{(001) 1234-5678}
2014-04-09 06:21:14.651 iOS-Tutorial[3703:a0b] Values: {19, 16}
