    NSAttributedString has to be set using UILabel's attributedText property. e.g [syncStatusLabel setAttributedText:str] in your case. Good Luck!

    Try this with swift (execute code with following extension)

    extension NSMutableAttributedString {
    
        func setColorForText(textToFind: String, withColor color: UIColor) {
            let range: NSRange = self.mutableString.range(of: textToFind, options: .caseInsensitive)
            self.addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range)
        }
    
    }
    

    Try an extension with UILabel:

    self.view.backgroundColor = UIColor.blue.withAlphaComponent(0.5)
    let label = UILabel()
    label.frame = CGRect(x: 40, y: 100, width: 280, height: 200)
    
    let stringValue = "Hello. That is a test attributed string."  // or direct assign single string value like "firstsecondthird"
    label.textColor = UIColor.lightGray
    label.numberOfLines = 0
    let attributedString: NSMutableAttributedString = NSMutableAttributedString(string: stringValue)
    attributedString.setColorForText(textToFind: "Hello", withColor: UIColor.yellow)
    attributedString.setColorForText(textToFind: "That", withColor: UIColor.green)
    
    label.font = UIFont.systemFont(ofSize: 26)
    label.attributedText = attributedString
    self.view.addSubview(label)
    

    Here is result:

    you can set text color with pattern image like bellow..

            [yourLable setTextColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"yourImageName"]]];
    

    and also set different color with this bellow code.. please check tutorial with detail mate..

    NSString *test = @"Hello. That is a test attributed string.";
    
     CFStringRef string =  (CFStringRef) test;
        CFMutableAttributedStringRef attrString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0);
        CFAttributedStringReplaceString (attrString,CFRangeMake(0, 0), string);
    
    
    
        /*
         Note: we could have created CFAttributedStringRef which is non mutable, then we would have to give all its
         attributes right when we create it. We can change them if we use mutable form of CFAttributeString.
         */
    
    
    
        //Lets choose the colors we want to have in our string
        CGColorRef _orange=[UIColor orangeColor].CGColor;
        CGColorRef _green=[UIColor greenColor].CGColor;
        CGColorRef _red=[UIColor redColor].CGColor;
        CGColorRef _blue=[UIColor blueColor].CGColor;    
    
    
    
    
        //Lets have our string with first 20 letters as orange
        //next 20 letters as green
        //next 20 as red
        //last remaining as blue
        CFAttributedStringSetAttribute(attrString, CFRangeMake(0, 20),kCTForegroundColorAttributeName, _orange);
        CFAttributedStringSetAttribute(attrString, CFRangeMake(20, 20),kCTForegroundColorAttributeName, _green);
        CFAttributedStringSetAttribute(attrString, CFRangeMake(40, 20),kCTForegroundColorAttributeName, _red);    
        CFAttributedStringSetAttribute(attrString, CFRangeMake(60, _stringLength-61),kCTForegroundColorAttributeName, _blue);
