I had a UITextView that detects phone numbers and links, but this overrides my fontColor and change it to blueColor. Is there a way to format the color of auto detected links, or should I try a manual version of this function?
Can I change the color of auto detected links on UITextView?

Instead of using an UITextView, I used an UIWebView and enabled the "auto-detect links". To change the link color, just created a regular CSS for the tag.
I used something like this:
NSString * htmlString = [NSString stringWithFormat:@"<html><head><script> document.ontouchmove = function(event) { if (document.body.scrollHeight == document.body.clientHeight) event.preventDefault(); } </script><style type='text/css'>* { margin:0; padding:0; } p { color:black; font-family:Helvetica; font-size:14px; } a { color:#63B604; text-decoration:none; }</style></head><body><p>%@</p></body></html>", [update objectForKey:@"text"]];
webText.delegate = self;
[webText loadHTMLString:htmlString baseURL:nil];
The problem with UITextView linkTextAttributes is that it applies to all automatically detected links. What if you want different links to have different attributes?
It turns out there's a trick: configure the links as part of the text view's attributed text, and set the linkTextAttributes to an empty dictionary.
Here's an example in iOS 11 / Swift 4:
// mas is the mutable attributed string we are forming...
// ... and we're going to use as the text view's `attributedText`
mas.append(NSAttributedString(string: "LINK", attributes: [
NSAttributedStringKey.link : URL(string: "https://www.apple.com")!,
NSAttributedStringKey.foregroundColor : UIColor.green,
NSAttributedStringKey.underlineStyle : NSUnderlineStyle.styleSingle.rawValue
]))
// ...
self.tv.attributedText = mas
// this is the important thing:
self.tv.linkTextAttributes = [:]
You can Change the Hyperlink Color in a TextView by the following:
In the Nib file, you can go to the Properties Window and change the Tint to which ever color you want to.
or you can also do it programatically by using the below code
[YOURTEXTVIEW setTintColor:[UIColor whiteColor]];
Swift 5 Answer
Nice and simple
myTextView.linkTextAttributes = [.foregroundColor: UIColor.white]
This is how I did it using Swift 5:
let attributedString = NSMutableAttributedString(string: myTextView.text ?? "")
myTextView.linkTextAttributes = [NSAttributedString.Key(rawValue: NSAttributedString.Key.foregroundColor.rawValue): UIColor.whiteColor] as [NSAttributedString.Key: Any]?
myTextView.attributedText = attributedString
