Use <code>NSAttributedString</code>

<pre><code>NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:@"Google" 
 attributes:@{ NSLinkAttributeName: [NSURL URLWithString:@"http://www.google.com"] }];
self.textView.attributedText = attributedString;
</code></pre>

Sure, you can set just a portion of the text to be the link. Please read more about the <code>NSAttributedString</code> <a href="https://developer.apple.com/library/ios/documentation/Cocoa/Conceptual/AttributedStrings/AttributedStrings.html" rel="noreferrer">here</a>.

If you want to have more control and do something before opening the link. You can set the delegate to the <code>UITextView</code>.

<pre><code>- (void)viewDidLoad {
 ...
 self.textView.delegate = self; // self must conform to UITextViewDelegate protocol
}

...

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
 // Do whatever you want here
 NSLog(@"%@", URL); // URL is an instance of NSURL of the tapped link
 return YES; // Return NO if you don't want iOS to open the link
}
</code></pre>

if you want active substring in your UITextView then you can use my extended TextView... its short and simple. You can edit it as you want.

how to use (range = substring location):

<pre><code>[self.textView addTapActionWithRange:range withActionBlock:^{
 // anything you want to do - show something
}];
</code></pre>

<h1>Swift 3, iOS10 , Xcode 9</h1>
@sikhapol's answer is really nice if you knew exactly the words you want to parse like &quot;word dictionary&quot; somehow
it's all about the string itself that displayed
in UITextView
My solution is based on the text rendering
if you make the UITextView render HTML tags you may use href tag
Here is some Code references you may use
first, you need to configure UITextView from interface builder or form code
to
<ol>
<li>Selectable</li>
<li>Data detectores</li>
</ol>
<h1>Note: do not make the textview editable</h1>
Interface builder
<a href="https://i.stack.imgur.com/x195A.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/x195A.png" alt="enter image description here" /></a>
programmatically
<pre><code> let htmlData = NSString(string: &quot;go to &lt;a href=\&quot;http://www.google.com\&quot;&gt;google&lt;/a&gt; and search for it&quot;).data(using: String.Encoding.unicode.rawValue)


 let attributedString = try! NSAttributedString(data: htmlData!, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)
 yourUIViewView.isSelectable = true
 yourUIViewView.dataDetectorTypes = .link
 yourUIViewView.attributedText = attributedString
 yourUIViewView.delegate = self
</code></pre>
for the UITextViewDelegate
<pre><code> func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -&gt; Bool {
 
 // check for the url string for performing your own custom actions here
 let urlString = URL.absoluteString
 
 // Return NO if you don't want iOS to open the link
 return true
 }
</code></pre>

A nifty little extension that I wrote and use (Swift 4.2, tested on iOS 12.1)

<pre><code>extension NSAttributedString {
 func replace(placeholder: String, with hyperlink: String, url: String) -&gt; NSAttributedString {
 let mutableAttr = NSMutableAttributedString(attributedString: self)

 let hyperlinkAttr = NSAttributedString(string: hyperlink, attributes: [NSAttributedString.Key.link: URL(string: url)!])

 let placeholderRange = (self.string as NSString).range(of: placeholder)

 mutableAttr.replaceCharacters(in: placeholderRange, with: hyperlinkAttr)
 return mutableAttr
 }
}
</code></pre>

Usage:

<pre><code>//Set through code or through interface builder
footerText.isSelectable = true
footerText.dataDetectorTypes = .link

//Keeps the original formatting from xib or storyboard
footerText.text = "By continuing, you are indicating that you accept our @Terms@ and @Privacy@."
footerText.attributedText = footerText.attributedText?
 .replace(placeholder: "@Terms@", with: "Terms and Conditions", url: AppUrl.terms)
 .replace(placeholder: "@Privacy@", with: "Privacy Policy", url: AppUrl.privacy)

Since the edit queue was full, I'll post my version of an answer here. It's based on Amr Angry's answer.
I'm using DispatchQueue.main.async { ... } since the app will crash if the NSAttributedString is running on a background thread.
<pre><code>guard let htmlData = NSString(string: &quot;go to &lt;a href=\&quot;http://www.google.com\&quot;&gt;google&lt;/a&gt; and search for it&quot;).data(using: String.Encoding.unicode.rawValue) else { return }
 
DispatchQueue.main.async {
 do {

 let attributedString = try NSAttributedString(data: htmlData, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)
 yourUIViewView.isSelectable = true
 yourUIViewView.dataDetectorTypes = .link
 yourUIViewView.attributedText = attributedString
 yourUIViewView.delegate = self

 } catch {
 print(&quot;Cannot setup link with \(htmlData)!&quot;)
 }
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -&gt; Bool {

 // Return NO if you don't want iOS to open the link
 return true
}
</code></pre>

I am trying to create a <code>UITextView</code> with a <code>hyperlink</code> so that when the user clicks on the link, they are taken to <code>safari</code> to open the webpage. I have read on link detectors for a <code>textview</code> but those samples always show link detection working if an actual url is present in the text (ie. <a href="http://google.com" rel="noreferrer">www.google.com</a>). I want it to be regular text that, when clicked, opens an associated URL. (ie. Google is the text and when clicked, opens up a url <a href="http://google.com" rel="noreferrer">www.google.com</a>). How can I accomplish this in iOS7/8?
