Answer
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
…
[someLabel setHtml:@"Be <b>bold!</b>"];
