I have a problem with label and I don't understand where is the solution.
I set my label with "Word Wrap" and 3 lines but it cut a word when text wrap...why??
thanks
Probably bounds are too small? Stretch the UILabel out as much as possible (height-wise), set lines to 999 and see if it still cuts it.
edit: Somehow this still gets views. More recent versions of iOS no longer have as many issues with UILabel, so this no longer applies. (especially with Auto Layout)
This is a really common problem when trying to use multi-line UILabels. The short answer is to use a UITextField instead if you want multiple lines of text. You get more control over the padding around the text as a bonus.
(yes, you can 'fix' the UILabel but sometimes simpler solutions are better)

Using autolayout to have a multiline UILabel auto size the text to fit does not work for single words.
Here is how storyboard is set up:
Here's the problem.
This does not display properly:
But this does:
I have adjusted every setting in the storyboard. I have changed all of the Line Break settings (wrap, truncate, etc), I have adjusted # of lines, I have made text plain vs attributed, I've changed font sizing and scaling, everything. What am I missing? Why does "California" get cut off instead of shrinking to fit? I've seen many other posts on SO and haven't yet found a solution (which needs to be compatible back to iOS 9)
Your label is being filled both horizontally and vertically until it runs out of space, then it starts shrinking the text to fit. In the one word example it breaks the word into two lines because there is vertical room.
Do you know in advance or can you calculate in the app when you have only one word in this label? If so you can change the number of lines to 1 instead of 0 so the app will keep the contents on one line and shrink this word.
I have a number of UILabels on a view and a varying amount of text in each. I need the font size to be the same in each.
I’m using autolayout to position / size the labels.
However some of the “g” characters are being cut off.
I’m not sure how I can resolve this ?
change the lines property of the lables to 0 and hook then properly to each other or to the superView so when there content is large they wrap smoothly
You cannot control font size directly via auto-layout constraints. You can disable adjusting font on all labels and this way they will have same label.
But to better help answering your question (and underlaying issue you're trying to solve) - it would be much better if you share screenshot with your interface.
SizeToFit fixes my issue, rather than autolayout
I have some ASCII syntax diagrams which must not have line breaks in the middle.
These don't have to be editable so I thought the best way is to use an UILabel with auto shrink option. But this option shrinks the text also if the content doesn't fit the height of the labels frame rectangle.
I just want to shrink only if the content doesn't fit the width. It would be absolutely fine to scroll vertically through the text.
What is the best way to do this with UILabel or any other UI element?
Use UITextView with 'editable' property set to false.
So let me rephrase your question. I guess what you want is a UILabel which can show multiple lines, but the longest line need to fit into the width of UILabel. If this is what you want, well the imagination is weird to me...
But anyway, I feel there's a conflict in your settings. First, allowing multiple lines implies you set "Lines" attribute (number of lines) as 0, which allows unlimited lines. But then Autoshrink will play no effect. I'm afraid it is not possible to be done by just setting the storyboard and instead, you need to write some code.
I guess people have raised related questions earlier, by which they want to dynamically change the font size when the text become too long. I guess you want to take a look about this:
Autoshrink on a UILabel with multiple lines
The last issue is you also want the scrolling effect (this is why I feel the outlooking will be weird.) But in short, to achieve this you need 1) dynamically change the UILabel height, most likely using the same technique as explained in the reference thread, and 2) wrap the UILabel in a scroll view. Maybe this can achieve what you want.
I've been working with a label on a storyboard and can't seem to get it to behave correctly. I have my lines set to 0 because I display a couple different things in the label, depending on what the user clicked before. 3 or 4 words will display fine and on multiple lines, but when I get to a larger single word it will break the word in half. I don't won't it to do this, I just want it to resize and stay on a single line if it's only one word. Any ideas how to do this? I already have it working so that it will auto resize long text to fit there, the only problem is this.
If a UILabel is too small in its width, it cuts off the last part of the text or breaks its content into another line. As one word does not break into half automatically it can't be displayed entirely and therefore is cut off at its end.
In order to solve your problem I have some suggestions:
Change the number of lines to at least 1
Update your frames
Resize the UILabel so it can display the entire word.
Take a look at your constraints, as they might force the UILabel to resize under certain conditions.
I hope this might help you.
I have a view which has a lot of labels. Some of them get the text set dynamically. Sometimes the text is to long to display it within one line. I know how i can display the text in multiple lines. My problem is that when i do display the text in multiple lines then the margins are broken between the labels. Sometimes a label even swapes into the content of the next label.
I want to avoid fixing this "by hand" (repositioning of all other elements). Maybe Autolayout can fix this, but sadly i'm not able to use it for now. But it would be a good argument to convert my project from springs&struts into autolayout. However, maybe there is another way to fix this issue. Would be nice if somebody can help me out. Thanks in advance!
You can use sizeWithFont:constrainedToSize:lineBreakMode: to calculate the height which will be required by each of the labels. You should use this in a loop which iterates over each label in the order they should appear on screen. As you go, increment the y position by the height of the current label and the margin. Each label will now have the correct position and at the end of the loopy will hold the full required height.
