BHUPI s answer is correct  but if you would like to combine your custom font from UILabel or UITextView with HTML content  you need to correct your html a bit   NSString  htmlString      lt b gt Bold lt  b gt  lt br gt  lt i gt Italic lt  i gt  lt p gt   lt del gt Deleted lt  del gt  lt p gt List lt ul gt  lt li gt Coffee lt  li gt  lt li type  square  gt Tea lt  li gt  lt  ul gt  lt br gt  lt a href  URL  gt Link  lt  a gt     htmlString    htmlString stringByAppendingString    lt style gt body font-family  YOUR FONT HERE   font-size  SIZE    lt  style gt       Example    htmlString    htmlString stringByAppendingString  NSString stringWithFormat    lt style gt body font-family        font-size  fpx   lt  style gt    myLabel font fontName  myLabel font pointSize        NSAttributedString  attributedString     NSAttributedString alloc                        initWithData   htmlString dataUsingEncoding NSUnicodeStringEncoding                             options     NSDocumentTypeDocumentAttribute  NSHTMLTextDocumentType                   documentAttributes  nil                              error  nil                textView attributedText   attributedString    You can see the difference on the picture  below

For some cases UIWebView is a good solution  Because    it displays tables  images  other files it s fast  comparing with NSAttributedString  NSHTMLTextDocumentType  it s out of the box   Using NSAttributedString can lead to crashes  if html is complex or contains tables  so example   For loading text to web view you can use the following snippet  just example    func loadHTMLText   text  String   font  UIFont            let fontSize   font pointSize   UIScreen screens 0  scale         let html                lt html gt  lt body gt  lt span style   font-family    font fontName   font-size    fontSize    color   112233  gt   text        lt  span gt  lt  body gt  lt  html gt                      self loadHTMLString html  baseURL  nil

NSDoc save the text file in a string to an html file then simultaneously load it into a webview that is in the same place as your UITextView

You can have a look the OHAttributedLabel classes  I used these to overcome this kind of problem with my textField  In this they have overridden the drawRect method to obtain the required style   https   github com AliSoftware OHAttributedLabel

Use a UIWebView on iOS 5-    On iOS 6  you can use UITextView attributedString  see https   stackoverflow com a 20996085 for how     There s also an undocumented - UITextView setContentToHTMLString   method  Do not use this if you want to submit to AppStore

Answer has fitted to me that from BHUPI   The code transfer to swift as below   Pay attention  allowLossyConversion  false   if you set the value to true  it will show pure text   let theString     lt h1 gt H1 title lt  h1 gt  lt b gt Logo lt  b gt  lt img src  http   www aver com Images Shared logo-color png  gt  lt br gt  end            let theAttributedString   try  NSAttributedString data  theString dataUsingEncoding NSUTF8StringEncoding  allowLossyConversion  false                options   NSDocumentTypeDocumentAttribute  NSHTMLTextDocumentType               documentAttributes  nil           UITextView Message attributedText   theAttributedString

My first response was made before iOS 7 introduced explicit support for displaying attributed strings in common controls  You may now set attributedText of UITextView to an NSAttributedString created from HTML content using   - id initWithData  NSData   data options  NSDictionary   options documentAttributes  NSDictionary    dict error  NSError    error    - initWithData options documentAttributes error   Apple Doc    Original answer  preserved for history   Unless you use a UIWebView  your solution will rely directly on CoreText  As ElanthiraiyanS points out  some open source projects have emerged to simplify rich text rendering  I would recommend NSAttributedString-Additions-For-HTML  Edit  the project has been supplanted DTCoreText   which features classes to generate and display attributed strings from HTML

You can also use one more way  Three20 library offers a method through which we can construct a styled textView  You can get the library here  http   github com facebook three20   The class TTStyledTextLabel has a method called textFromXHTML  I guess this would serve the purpose  But it would be possible in readonly mode  I don t think it will allow to write or edit HTML content    There is also a question which can help you regarding this  HTML String content for UILabel and TextView  I hope its helpful
