In this post, We are dealing with a dynamic content and we need to handle web links
and the navigation in the content in an iOS app.
Suppose, below is the dynamic content you got from server. Could be with multiple web links in it also.
Please subscribe www.iossolves.blogspot.com
The weblink should be displayed as a link and we should be in a position to handle the tap of that link.
Where to redirect user and all.
The best solution to handle this is to take a UITextView and turn on web link detection.
--------------------------------------------------------------------------------------------------
self.tv.text = "Please subscribe www.iossolves.blogspot.com. Thank You!"
self.tv.delegate = self
self.tv.dataDetectorTypes = [.link]
--------------------------------------------------------------------------------------------------
We can also turn on link detection from Interface builder also.

| Simulator |
In the delegate methods, we can check the url and play with the navigation.
--------------------------------------------------------------------------------------------------
@available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith URL: URL,
in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
return true
}
func textView(_ textView: UITextView, shouldInteractWith URL: URL,
in characterRange: NSRange) -> Bool {
return true
}
--------------------------------------------------------------------------------------------------
Suppose If I need to block blog sites, We can do that like shown below.
--------------------------------------------------------------------------------------------------
func textView(_ textView: UITextView, shouldInteractWith URL: URL,
in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
if URL.absoluteString.contains("blogspot") { //Blocking Blog sites
print("Restricted Site!")
return false
}
return true
}
