问题 Update 1 I found a work-around: // instead of font = [font fontWithSize:pointSize]; // i can do this and get the correct font back font = [UIFont fontWithName:font.fontName size:pointSize] I'm using Nick Lockwood's HTMLLabel class to turn HTML into an NSAttributedString that respects the styling within the HTML. For the most part, it works great. However, I'm using a custom font in my app, and for some reason, my font is always getting rendered in bold. I don't have this problem using the

问题 I wish to draw a customizable line inside a UITextView consisting of some text (using NSAttributedString ) Here's what I tried NSString *unicodeStr = [NSString stringWithFormat:@"%C%C%C", 0x00A0, 0x0009, 0x00A0]; //nbsp, tab, nbsp NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:unicodeStr]; NSRange strRange = NSMakeRange(0, str.length); NSMutableParagraphStyle *const tabStyle = [[NSMutableParagraphStyle alloc] init]; tabStyle.headIndent = 16; //padding on

问题 I've used this answer in order to create a CGRect for a certain range of text. In this UITextView I've set it's attributedText (so I've got a bunch of styled text with varying glyph sizes). This works great for the first line of text that's left aligned, but it has some really strange results when working with NSTextAlignmentJustified or NSTextAlignmentCenter . It also doesn't calculate properly when the lines wrap around or (sometimes) if there are \n line breaks. I get stuff like this (this

问题 What is the best way to display lots of RichText (HTML formatted) At the moment I'm working on an app for a forum. As you'd expect the posts on the site have lots of HTML formatting, lists, images bold text , colored text, etc... Now there are several options I can think of (non of them ideal, please if you think of any other options post them in the comments): Custom Cells using NSAttributedString+HTML + DTAttributedTextView for each post? Problems: I used the NSAttributedString+HTML

问题 Trying to display super/subscript text using NSAttributedString in a UITextView seems broken in iOS13 - unless anyone knows otherwise? Curiously if I use the UIFont systemFont then it works - but if I use any other font it doesn't. See below for my code to setup a UITextView in my test app. - (void)viewDidLoad { [super viewDidLoad]; UIFont* font = [UIFont systemFontOfSize:32]; //UIFont* font = [UIFont fontWithName:@"Helvetica Neue" size:32]; //UIFont* font = [UIFont fontWithName:@"Courier"

问题 I have a UITextView that contains a link and some other text. The link detection is enabled and working (iOS8). However, I am at loss to find the range of the link within the textView. The idea is that the text is scanned (after link detection is done) and the link preloaded into a web view, so that when a user taps on an element somewhere, the web view can reveal itself. How can I get the range of the detected link within a UITextView? 回答1: A way to do it, is to use enumerateAttribute

问题 Want to change alignment of html label. Nothing works. I don't see any CSS in the HTML. There are no further settings changing the alignment. I also set left alignment directly on the UILabel. What am I missing? The code is in UILabel extension. NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init]; paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping; paragraphStyle.alignment = NSTextAlignmentLeft; NSDictionary *attr = @{NSDocumentTypeDocumentAttribute:

问题 I need the text of a UILabel to be black, but have a light gray underline under the text. Is this possible with NSAttributedString or TTTAttributedLabel ? Or is custom drawing using Core Graphics needed? CLARIFICATION: I need a specific color text on a different color underline. Example: blue text on red underline. 回答1: You can do with NSAttributedString as below. NSMutableAttributedString* string = [[NSMutableAttributedString alloc]initWithString:@"you string"]; [string addAttribute
