I'm designing iOS and Android apps full-time for over a year now. A couple of tips from me: - He's very right about previewing on the device. I like xScope better than Silkscreen, because it can stream anything, both file, or screen region, and overall it's a nice designer's utility belt. There's nothing like that for android, at least I haven't found anything that works, and Android needs this even more, because it…

For bolding text, create an attributed string and draw it with CoreText. http://stackoverflow.com/questions/8322020/display-nsattribu... If you only support iOS 6, you can use a UILabel and set the "attributedText" property. I notice a lot of new iOS developers jump to open source libraries to abstract away important frameworks. It might save an hour, but I think it's counterproductive to not do things by hand the fi…

  NSString *theEntireLineOfText = @"Hello World";
  UIColor *boldColor = [UIColor blackColor];
  UIFont *myFont = [UIFont fontWithName:@"Helvetica" size:12.0];
  UIColor *baseColor = [UIColor grayColor];
  NSDictionary *subAttrs = [NSDictionary dictionaryWithObjectsAndKeys:
                              myFont, NSFontAttributeName, boldColor,NSForegroundColorAttributeName, nil];
   NSMutableAttributedString *mainText = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@",theEntireLineOfText] attributes:@{NSFontAttributeName:myFont,NSForegroundColorAttributeName:baseColor}];
  // Make the word "World" black"
  NSRange range = NSMakeRange(0,[@"World" length]);
        [mainText setAttributes:subAttrs range:range];

Earlier quoted context omitted.

You might be interested in something I plan to open source at some point: a native Markdown lexing / parsing engine meant to be used to stylize markdown for Core Text / NSAttributedString. Here's the meat of it in a gist: https://gist.github.com/29dabe4b6e762ee221df

Thanks a lot for the link, I was going to write Markdown -> NSAttributedString library myself, because I couldn't find one. Right now I'm just using DTCoreText and convert Markdown to HTML on the server.
