 ### Setting Attributes for An Icon
 ```objective-c
 [starIcon addAttribute:NSForegroundColorAttributeName value:[UIColor
 whiteColor]];
 ```

 ```swift
-let starIcon: FAKFontAwesome?
-do {
-  starIcon = try FAKFontAwesome.init(identifier: "er", size: 15)

 ```
 `NSAttributedString` did all the magics behind the scene. So you can set those attributes supported by `NSAttributedString` to an icon. For all available attributes, see [NSAttributedString UIKit Additions Reference](https://developer.apple.com/library/ios/documentation/UIKit/Reference/NSAttributedString_UIKit_Additions/Reference/Reference.html#//apple_ref/doc/uid/TP40011688-CH1-SW16)
