Display Rich Text Content as UIWebView or UILabel+CoreText

I'd like to display rich text content in my app. I want user to create simple WYSIWYG input with support of bold, italics, shadow, outline, image HTML-like tags. I am puzzled if I should go with UIWebView or custom written UILabel/UIView which can have CoreText framework added to support all those above stated properties. I see there are libraries which are using both approaches.I'd like to display rich text content in my app
