Color change by tap word in UITextView

[Piyush]

Hello,

I want to change color of word when i tap in UITaxview just like in InstaQuote
I write some code
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(textTapped:)];
   
    [_textview addGestureRecognizer:tap];


- (void)textTapped:(UITapGestureRecognizer *)recognizer
{
    UITextView *textView = (UITextView *)recognizer.view;
   
    // Location of the tap in text-container coordinates
   
    NSLayoutManager *layoutManager = textView.layoutManager;
    CGPoint location = [recognizer locationInView:textView];
    location.x -= textView.textContainerInset.left;
    location.y -= textView.textContainerInset.top;
   
    NSLog(@"location: %@", NSStringFromCGPoint(location));
    NSLog(@"%@",[self getWordAtPosition:location inTextView:_lbl_test]);

//I got word which i tapped but How to change color of word which I tapped. I have little knowledge of NSMutableAttributedString. but didn't know how? can anyone suggest me what i do?

   
    }


-(NSString*)getWordAtPosition:(CGPoint)pos inTextView:(UITextView*)_tv
{

    pos.y += _tv.contentOffset.y;   
    UITextPosition *tapPos = [_tv closestPositionToPoint:pos];   
    UITextRange * wr = [_tv.tokenizer rangeEnclosingPosition:tapPos withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];   
    return [_tv textInRange:wr];
}

Disclaimer: I've never done this, but it looks interesting so I looked it up. 

It looks like this code will turn the string in the given range red (you may need NSForegroundColorAttributeName pre iOS7):

[string addAttribute:UITextAttributeTextColor 
               value:[UIColor redColor] 

               range:range];        

Here are some extra resources I found:
