Two different text color not working

[ChiragKothiya1996]

In label set text like "text with #tag and www.example.com".

my need is set red color for "www.example.com" and green color for "#tag".

But it set blue color.

Following is my code:

[label setText:@"text with #tag and www.example.com" afterInheritingLabelAttributesAndConfiguringWithBlock:^ NSMutableAttributedString *(NSMutableAttributedString *mutableAttributedString) {
	NSRange rangeUrl = [[mutableAttributedString string] rangeOfString:@"www.example.com" options:NSCaseInsensitiveSearch];
    NSRange rangeTag = [[mutableAttributedString string] rangeOfString:@"#tag" options:NSCaseInsensitiveSearch];
    UIFont *boldSystemFont = [UIFont systemFontOfSize:IS_IPAD?16:14 weight:UIFontWeightRegular];
    CTFontRef font = CTFontCreateWithName((__bridge CFStringRef)boldSystemFont.fontName, boldSystemFont.pointSize, NULL);
    if (font) {

		[mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)font range:rangeUrl];
		[mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName value:[UIColor redColor] range:rangeUrl];

		[mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)font range:rangeTag];
  		[mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName value:[UIColor greenColor] range: rangeTag];
		[mutableAttributedString addAttribute:(NSString *)kCTUnderlineColorAttributeName value:[UIColor clearColor] range: rangeTag];

		CFRelease(font);
	}
	return mutableAttributedString;
}];
