问题 How do I set a UILabel lineBreakMode to break words and add hyphens to broken words? a label with a broken wo- rd should look like this 回答1: Elaborating on Matt's answer here: https://stackoverflow.com/a/16502598/196358 it can be done using NSAttributedString and NSParagraphStyle.

问题 I am implemententing a "read more" functionality much like the one in Apple's AppStore. However, I am using a multiline UILabel . Looking at Apple's AppStore, how do they decrease the last visible line's width to fit the "more" text and still truncate the tail (see image)? 回答1: This seems to work, at least with the limited amount of testing I've done. There are two public methods. You can use the shorter one if you have multiple labels all with the same number of lines -- just change the

问题 When I dynamically change the text of a UILabel I would prefer to get an ellipsis (dot, dot, dot) rather then have the text be automatically resized. How does one do this? In other words, if I have UILabel with the word Cat with size font 14 and then I change the word to Hippopotamus the font shrinks to fit all the word. I would rather the word be automatically truncated followed by an ellipsis. I assume there is a parameter that can be changed within my UILabel object. I'd rather not do this

问题 Good Day, I am developing a workout app that works fine except when moving it to the background. The timer suspends when it does. I found an example of a background timer that I have working but now I can't get the UILabel that displays the duration of the workout to work. In the console it states that I am accessing an object from the main thread which I understand. What I don't know how to do is to get the UILabel to update as the timer updates from within the background thread with the

问题 I need to create a UILabel with a background color, and I'd like to add some left padding but every solution I've found around here seems like a nasty hack. Which is the 'standard' way to achieve this from iOS 5 ahead? EDIT A screenshot to illustrate my scenario.- 回答1: For a full list of available solutions, see this answer: UILabel text margin Try subclassing UILabel, like @Tommy Herbert suggests in the answer to [this question][1].

问题 Im working on an ios app using objective c and i have an issue with uilabel that i could use some help with. Basically i have a label that can change size to fit the text that it will display but it has a max height that it can possible be. the label itself has a fixed width at all times. i have turned on UILineBreakModeWordWrap and UILineBreakModeTailTruncation to make the text fit and truncate but this causes the text to truncate the tail too early when it has only 1 word left to place.
