André Rodrigues Since iOS 7 you can use NSAttributedString with HTML syntax: NSURL *htmlString = [[NSBundle mainBundle] URLForResource: @"string" withExtension:@"html"]; NSAttributedString *stringWithHTMLAttributes = [[NSAttributedString alloc] initWithFileURL:htmlString options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType} documentAttributes:nil error:nil]; textView.attributedText = stringWithHTMLAttributes; // attributedText field!

iOS 7 BUG - NSAttributedString does not appear

由 百般思念 提交于 2019-11-27 13:55:42
Last week I asked a question about a Simulator bug with NSAttributedString not displaying: iOS 7 Simulator Bug - NSAttributedString does not appear Unfortunately it now appears this is not a simulator bug but an iOS 7 bug. I have now reproduced this issue on an iPhone 5 device. The bug appears to be the combination of using NSUnderlineStyleAttributeName & NSParagraphStyleAttributeName as attributes for a NSAttributedString. I have only tested on two iOS 7 devices so far, and the issue has only appeared on one of them. Even after they have both been upgraded to the exact same version: 1st

Saving custom attributes in NSAttributedString

由 心不动则不痛 提交于 2019-11-27 12:30:59
I need to add a custom attribute to the selected text in an NSTextView. So I can do that by getting the attributed string for the selection, adding a custom attribute to it, and then replacing the selection with my new attributed string. So now I get the text view's attributed string as NSData and write it to a file. Later when I open that file and restore it to the text view my custom attributes are gone! After working out the entire scheme for my custom attribute I find that custom attributes are not saved for you. Look at the IMPORTANT note here: http://developer.apple.com/mac/library

UITextView: Disable selection, allow links

由 不羁的心 提交于 2019-11-27 10:47:50
问题 I have a UITextView which displays an NSAttributedString . The textView's editable and selectable properties are both set to false . The attributedString contains a URL and I'd like to allow tapping the URL to open a browser. But interaction with the URL is only possible if the selectable attribute is set to true . How can I allow user interaction only for tapping links, but not for selecting text? 回答1: I find the concept of fiddling with the internal gesture recognizers a little scary, so

How to get height for NSAttributedString at a fixed width

问题 I want to do some drawing of NSAttributedStrings in fixed-width boxes, but am having trouble calculating the right height they'll take up when drawn. So far, I've tried: Calling - (NSSize) size , but the results are useless (for this purpose), as they'll give whatever width the string desires. Calling - (void)drawWithRect:(NSRect)rect options:(NSStringDrawingOptions)options with a rect shaped to the width I want and NSStringDrawingUsesLineFragmentOrigin in the options, exactly as I'm using in
