Detect address from UITextView and show it map on tap

There is an opt开发者_高级运维ion in UITextView properties to detect address from the the text view text. However I am not able to do that. The text view is not in editable mode.

Do you know how to detect address from text view? Is there a format that the address must have to be detected from the text view?

A UITextView won't automatically detect if text entered in the control is an address or provide you with the data you need to map the address on a map. It is simple a control to display arbitrary text data to the user:

You typically use a text view to display multiple lines of text, such as when displaying the body of a large text document.

I am not familiar with any algorithms to detect an address from a block of text, but if you work that part out, you can use geocoding to translate from the address to the latitude/longitude value you need to display it on a map.

I realize this answer is 3 years too late, but I was recently struggling with a similar problem (data detector for phone on mapview). I had datadetectors turned on, and had editable turned off -- but I found that if I added a "\n" to the end of the string, the detector suddenly started working.

For future folks landing here from search results, check out NSDataDetector

let detector = try? NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue)

if detector?.firstMatch(in: textView.text, options: [], range: NSRange(textView.text) != nil,
  let addressRange = Range(match.range, in: textView.text) {

  let address = textView.text[range]
  // do something with address
}

I'm not using it in the context of an editable text view, but you could easily try to detect address (or other data type) each time the text view is edited
