Questions tagged [nsdatadetector]

The NSDataDetector class is a specialized subclass of the NSRegularExpression class designed to match data detectors. It is available in iOS 4.0 and later and available in OS X v10.7 and later. The issues related with NSDataDetector should be tagged with question with related iOS or OS X platforms.

The NSDataDetector class makes it easy to detect URLs inside a string using just a few lines of code. NSDataDetector class can match dates, addresses, links, phone numbers and transit information.

The results of matching content is returned as NSTextCheckingResult objects. However, the NSTextCheckingResult objects returned by NSDataDetector are different from those returned by the base class NSRegularExpression. Results returned by NSDataDetector will be of one of the data detectors types, depending on the type of result being returned, and they will have corresponding properties. For example, results of type NSTextCheckingTypeDate have a date, timeZone, and duration; results of type NSTextCheckingTypeLink have a URL, and so forth.

Source: NSDataDetector Class Reference

Example:

NSError *error = NULL;
NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypeLink|NSTextCheckingTypePhoneNumber
                                                          error:&error];
