Attributed Strings in iOS6 Non Umemoto @umekun123 1210݄5༵ۚ
iOS5 You have limited power with NSString 1210݄5༵ۚ
iOS5 NSString in UILabel 1210݄5༵ۚ
UILabel *label = [[UILabel alloc] init]; ~~ some codes for
label ~~ label.text = @"Listen to the web"; 1210݄5༵ۚ
iOS6 You have more power with NSAttributedString There are a
lot of hassles for using CoreText, right? 1210݄5༵ۚ
iOS6 NSAttributedString NSKernAttributeName 1210݄5༵ۚ
UILabel *label = [[UILabel alloc] init]; ~~ some codes for
label ~~ NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"Listen to the web"]; NSInteger stringLength = [attString length]; [attString addAttribute:NSKernAttributeName value:@5 range:NSMakeRange(0, stringLength)]; label.attributedText = attString; 1210݄5༵ۚ
iOS6 NSAttributedString NSForegroundColorAttributeName 1210݄5༵ۚ
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"Listen to the web"]; UIColor
*_red = [UIColor redColor]; [attString addAttribute:NSForegroundColorAttributeName value:_red range:NSMakeRange(0, 6)]; label.attributedText = attString; 1210݄5༵ۚ
iOS6 NSAttributedString NSUnderlineStyleAttributeName 1210݄5༵ۚ
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"Listen to the web"]; [attString
addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:2] range:NSMakeRange(10, 7)]; label.attributedText = attString; 1210݄5༵ۚ
Available in UIKit • UITextView • UITextField • UILabel •
UIButton • UITableView • UIPickerVIew for example... 1210݄5༵ۚ
Available Attributes • Font • Text color • Paragraph style
• Text background color • Ligature, kerning, and baseline offset • Underline and strike-through • Stroke width and color • Shadow 1210݄5༵ۚ
One more thing A little bit advanced talk from now,
(and personal) 1210݄5༵ۚ
Can I use this for Syntax Highlighting on UITextView? 1210݄5༵ۚ
On my web speaker app, I wanna highlight the text
being spoken in real time. (Without using CoreText.) This is UITextView. 1210݄5༵ۚ
Something like this. With NSAttributedString. 1210݄5༵ۚ
Unfortunately, we need to reset UITextView every time setting a
new attributedString. textView.attributedText = attString So, it can be too SLOW for long text. (It must be ok for short text) 1210݄5༵ۚ
Possible textView replaceRange:(UITextRange *) withText:(NSString *) Not Possible textView replaceRange:(UITextRange
*) withText: (NSAttributedString *) 1210݄5༵ۚ
1210݄5༵ۚ
Anyway, it doesn’t matter for most of developers. NSAttributedString for
iOS is really nice! 1210݄5༵ۚ
Thank you If you are interested, check out the session
of WWDC2012 to find out more. “Session 222 - Introduction to Attributed Strings for iOS” 1210݄5༵ۚ
