To render this text properly in UILabel or UITextView, you need to convert it to NSAttributedString . NSAttributedString has built-in support for this conversion. First, we need to convert HTML string to Data . let htmlString = "This is a <b>bold</b> text."
To change the font or the size of a UILabel in a Storyboard or . XIB file, open it in the interface builder. Select the label and then open up the Attribute Inspector (CMD + Option + 5). Select the button on the font box and then you can change your text size or font.
You can do it without any third-party libraries by using attributed text. I believe it does accept HTML fragments, like the one you're getting, but you may want to wrap it in a complete HTML document so that you can specify CSS:
static NSString *html = @"<html>" " <head>" " <style type='text/css'>" " body { font: 16pt 'Gill Sans'; color: #1a004b; }" " i { color: #822; }" " </style>" " </head>" " <body>Here is some <i>formatting!</i></body>" "</html>"; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, 200)]; NSError *err = nil; label.attributedText = [[NSAttributedString alloc] initWithData: [html dataUsingEncoding:NSUTF8StringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes: nil error: &err]; if(err) NSLog(@"Unable to parse label text: %@", err); Not concise, but you can mop up the mess by adding a category to UILabel:
@implementation UILabel (Html) - (void) setHtml: (NSString*) html { NSError *err = nil; self.attributedText = [[NSAttributedString alloc] initWithData: [html dataUsingEncoding:NSUTF8StringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes: nil error: &err]; if(err) NSLog(@"Unable to parse label text: %@", err); } @end …
