ios7 font size change when create nsattributedstring from html

由 不问归期 提交于 2019-11-26 09:43:27
问题 I have a UITextView where I\'m managing an NSAttributedString, initially entered as normal via the keyboard. I save the attributed string as HTML, which looks fine. When I load it again, and convert it back to an attributed string from the HTML, the font size appears to change. For example, the HTML on loading looks like this: <!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01//EN\" \"http://www.w3.org/TR/html4/strict.dtd\"> <html> <head> <meta http-equiv=\"Content-Type\" content=\"text/html;
