Attribute ranges of characters in a UItextview with NSAttributedString?

Question

I have the following text in a UITextview

Hello! The car to your top right is where you setup your car specifications - don't worry, it takes only 30 seconds and you only ever have to set it up once!

I would like to:

bold the "Hello!" and make it a size bigger to 17
underline the "only 30 seconds"
make the "once!" red.

How do I do this? I have very minimal knowledge with NSAttributedString and have had no luck with the documentation.

Thankyou

get custom UITextview from https://www.cocoacontrols.com/search?utf8=%E2%9C%93&q=UITextView — iPatel, Jan 30 '14 at 09:15

Better you use the webview and make a htmlpage and set text style in it. or check this link http://www.cocoanetics.com/2011/01/befriending-core-text/ — kamalesh kumar yadav, Jan 30 '14 at 09:21
hmm the second link iPatel doesnt even compile...and the duplicate link does not help my problem at all. I have text in a textview, how do I attribute it from there? — Cescy, Jan 30 '14 at 09:22

This answer is perfect! thankyou so much, I did not know you could edit it so simply like this. Quite dissappointed with the other SO memebers who just downvoted this... – Cescy Jan 31 '14 at 02:48

Create Mutable Attributed string, do following steps

NSMutableAttributedString * attrString = [[NSMutableAttributedString alloc] initWithString:yourTextView.text];

1) Found Hello! range and set font with size

NSRange foundRange = [attrString rangeOfString:@"Hello!"];
if (foundRange.location != NSNotFound)
{
    [attrString beginEditing];
    [attrString addAttribute: NSFontAttributeName
                   value:[[UIFont boldSystemFontOfSize:17] fontName]
                   range:boldedRange];
    [attrString endEditing];
}

2) Search range for only 30 seconds and set underline style

foundRange = [attrString rangeOfString:@"only 30 seconds"];
if (foundRange.location != NSNotFound)
{
    [attrString beginEditing];
    [attrString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:1] range:foundRange];
    [attrString endEditing];
}

3) Search range for once! and set stroke color.

foundRange = [attrString rangeOfString:@"once!"];
if (foundRange.location != NSNotFound)
{
    [attrString beginEditing];
    [attrString addAttribute:NSStrokeColorAttributeName value:[UIColor redColor] range:foundRange];
    [attrString endEditing];
}

Finally set attributed string to your textview as

yourTextView.attributedText = attrString;

Note: The above only work with ios6+..

this is great as well thankyou! but the other answer was just so much more simpler. kudos my friend — Cescy, Jan 31 '14 at 02:50
I'm not seeing rangeOfString available to be called on an instance of NSMutableAttributedString in Swift 3 — vikzilla, Jun 12 '17 at 17:49
