copied!<p>I think, it is a very convenient way to use <code>regular expressions</code> to find a range for applying attributes. This is how I did it: </p> <pre><code>NSMutableAttributedString *goodText = [[NSMutableAttributedString alloc] initWithString:articleText]; NSRange range = [articleText rangeOfString:@"\\[.+?\\]" options:NSRegularExpressionSearch|NSCaseInsensitiveSearch]; if (range.location != NSNotFound) { [goodText addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Georgia" size:16] range:range]; [goodText addAttribute:NSForegroundColorAttributeName value:[UIColor brownColor] range:range]; } NSString *regEx = [NSString stringWithFormat:@"%@.+?\\s", [self.article.titleText substringToIndex:0]]; range = [articleText rangeOfString:regEx options:NSRegularExpressionSearch|NSCaseInsensitiveSearch]; if (range.location != NSNotFound) { [goodText addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Georgia-Bold" size:20] range:range]; [goodText addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:range]; } [self.textView setAttributedText:goodText]; </code></pre> <p>I was searching for a list of available attributes and didn't find them here and in a class reference's first page. So I decided to post here information on that. </p> <p><a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSAttributedString_AppKitAdditions/Reference/Reference.html#//apple_ref/doc/uid/20000167">Standard Attributes</a></p> <p>Attributed strings support the following standard attributes for text. If the key is not in the dictionary, then use the default values described below.</p> <pre><code>NSString *NSFontAttributeName; NSString *NSParagraphStyleAttributeName; NSString *NSForegroundColorAttributeName; NSString *NSUnderlineStyleAttributeName; NSString *NSSuperscriptAttributeName; NSString *NSBackgroundColorAttributeName; NSString *NSAttachmentAttributeName; NSString *NSLigatureAttributeName; NSString *NSBaselineOffsetAttributeName; NSString *NSKernAttributeName; NSString *NSLinkAttributeName; NSString *NSStrokeWidthAttributeName; NSString *NSStrokeColorAttributeName; NSString *NSUnderlineColorAttributeName; NSString *NSStrikethroughStyleAttributeName; NSString *NSStrikethroughColorAttributeName; NSString *NSShadowAttributeName; NSString *NSObliquenessAttributeName; NSString *NSExpansionAttributeName; NSString *NSCursorAttributeName; NSString *NSToolTipAttributeName; NSString *NSMarkedClauseSegmentAttributeName; NSString *NSWritingDirectionAttributeName; NSString *NSVerticalGlyphFormAttributeName; NSString *NSTextAlternativesAttributeName; </code></pre> <p><a href="https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/AttributedStrings/AttributedStrings.html#//apple_ref/doc/uid/10000036i">NSAttributedString programming guide</a></p> <p>A full class reference is <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSAttributedString_Class/Reference/Reference.html">here</a>. </p>
