iOS Auto Detect Links, Addresses, Dates, and more


Example

UITextView has built in support to auto detect a variety of data. The data that is able to be auto-detected currently includes:

enum {
   UIDataDetectorTypePhoneNumber   = 1 << 0,
   UIDataDetectorTypeLink          = 1 << 1,
   UIDataDetectorTypeAddress       = 1 << 2,
   UIDataDetectorTypeCalendarEvent = 1 << 3,
   UIDataDetectorTypeNone          = 0,
   UIDataDetectorTypeAll           = NSUIntegerMax
};

Enabling auto-detection

// you may add as many as you like by using the `|` operator between options
textView.dataDetectorTypes = (UIDataDetectorTypeLink | UIDataDetectorTypePhoneNumber);

If enabled, the text will appear as a hyperlink on the UITextView

Clickable data

To allow the link to be clicked (which will result in different actions depending on the data type) you must ensure that the UITextView is selectable but not editable and that user interaction is enabled

textView.editable = NO;
textView.selectable = YES;
textView.userInteractionEnabled = YES; // YES by default
