NSAttributedString tail truncation in UILabel

由 三世轮回 提交于 2019-12-03 14:46:44
问题 I'm using ContextLabel to parse @ , # and URL's. This is the best solution i found, cause it sizes correctly and dont affect performance. It firstly parses string at input and than converts it to NSAttributedString and after this assigns it to attributedText property of UILabel . Everything works as expected, except tail truncation - it's very incorrect ( see pic below ) Where shall i start digging - is it wrong attributes on attributed string? Or label layout issue? Thanks! 回答1: I had this

问题 I am trying to extract hashtags for a simple college project using ruby on rails. I am facing issue with tags that include only numericals and with tags with no space. text = "Pack my #box with #5 dozen liquor.#jugs link.com/liquor#jugs #2good #first#second" The regex I have is /(?:^|\s)#(\w+)/i (source) This regex returns #["box", "5", "2good", "first"] How to make sure it only returns #["box", "2good"] and ignore the rest as they are not 'real' hashtags? 回答1: Can you try this regex: /(?:^|

Say, i have a following string string = "#Sachin is Indian cricketer. #Tendulkar is right hand batsman. #Sachin has been honoured with the Padma Vibhushan award " I want o/p as "#Sachin|0|7;#Tendulkar|29|10;#Sachinn|63|7;" I tried following new_string = "" string.scan(/#\S+/).each{|match| new_string+="#{match}|#{string.index(match)}|#{match.length};" } which gives me "#Sachin|0|7;#Tendulkar|29|10;#Sachin|0|7;" So how i will get the starting index of each sub-string? This is actually quite a non-trivial task, and has been discussed quite a bit in other questions on SO. This is the most common

问题 I want to do the inverse of what I've been finding so far. I'm setting a lot of heights with js and I want to navigate to the hashtag in the url after the page has loaded. I'm guessing this is simple but I'm not seeing the obvious answer... for an example, check here... http://alavita.rizenclients.com/#story Attempted this using the code... $(window).load(function() { var hashTag = window.location.hash; window.location = '/' + hashTag; }); doesn't actually take me to the top of the tagged

_Actual_ Twitter format for hashtags? Not your regex, not his code— the actual one?

Update: Use Twitter's Entities if you can- they figured it out for you as well as other items. My case is that I just have the tweet without entities and all the extra metadata I've spent what I consider an unreasonable amount of time trying to find the actual format for hashtags. As far as my searching can tell- Twitter has not published one. I know that many people have come up with regex's to parse them, however, your lib's regex is not my lib's regex and maybe I don't like yours anyway. So I'm asking- is there any actual official spec? I don't want a regex answer, I want a BNF or something

How do you include hashtags within Twitter share link text?

问题 I'm writing a site with a custom tweet button that uses the www.twitter.com/share function, however the problem I am having is including hash '#' characters within the tweet text. For example: http://www.twitter.com/share?url=www.example.com&text=I+am+eating+#branstonpickel+right+now The tweet text comes out as ' I am eating ' and omits the hash and everything after. I had a quick look on the Twitter forums and learnt the hash '#' character cannot be part of the share url. On https://dev

Implementing twitter-like hashtag on rails

问题 I'm want to implement twitter-like hashtag on my app. Let's say I have user input to a text area "I'm coming to #london from #paris" then I want to build tag cloud of the hashtags. I'm thinking of using acts-as-taggable-on. So I find all of my hashtags from the text in the backend, then save it to tag field. Anyone has experience on this they would like to share? Thanks. 回答1: Yes, ActsAsTaggableOn should be fine. As @etang alluded to, it's a heavy gem, but it gets the job done. If you're
