I have very large amount of text characters that I am setting on a label with attributed text property in storyboard. However, it looks like the number of characters it allows is limited because I have been restricted to a certain amount.
I have already set lines of text to 0, which means that the number of lines should be unlimited. However, that did not work for me.
Is there a way I can increase the editor height so I can edit more characters? Any ideas?

For a UILabel of certain width, with certain font and font size, i want to calculate amount of characters that would make 7 lines worth of text inside it + ... (three dots showing continuation). Is there a fancier way to achieve this? Currently what i'm trying is counting up to X amount of characters or 7 new line characters, which ever comes first and i cut on the text right there.
More Detail:
Trying to make an expandable row Cell which contains the UILabel, i'm achieving this with auto layout... So to control the cell expansion, i change the text to be full text or a substring of that, with a button below which toggles between the string vs substring. All of that is working. The problem i'm getting is my method of finding the substring isnt very neat. Its not consistent on how it handles text of different combination of characters or newlines. I get variations of how it looks and sometimes it just ends with three dots on a new line rather than finishing on the 7th line.
Even using auto layout you can still use the lines property of UILabel to limit the number of lines displayed by the label.
So set it 7 and you'll get 7 or less rows. Just assign the complete text.
For example, I have the following two string: "How Munched is That Birdie in the Window?" and "S22 - E7". I want to present in the label the following: "How Munched is That Birdie in ... S22 - E7" If the string is too large according to the label's size and doesn't fit it". How you can see, the three dots are placed always in the first string, the second string is always shown full.
How can I achieve this?
Here is how to do it.
yourlabel.adjustsFontSizeToFitWidth = false
yourlabel.lineBreakMode = .byTruncatingMiddle
You can set the UILabel's ParagraphStyle LineBreakMode to byTruncatingMiddle, which will probably work in most cases with carefully planned label size. From the docs:
The line is displayed so that the beginning and end fit in the container and the missing text in the middle is indicated by an ellipsis glyph. This mode is used for single-line layout
If you want to guarantee none of the "S22 - E7" string is truncated, you would have more control using two labels and setting layout constraints such that the width of the protected label is preserved so that it can display the full string whenever possible, but that is probably overkill in most cases.
You may also find this answer helpful if decide to go a different route by manually manipulating the displayed string based on detecting how many characters will be visible given the width and font.
Good day folks,
Actually I'm going crazy, I did everything I could in order to solve this simple problem.
As you see, a simple label in a narrow space causes the single word "Verification" to be separated into two lines which is not acceptable of course.
I know that I could make number of lines only 1 and this will decrease font size, I tried all wraps modules and all fails.
What can I do to display the label as "Verification Process" without any separation of a single word? (I accept even shrinking font size or clipping last word).
The first one is default setting
Does these two settings below meet your needs?
If you are ok with clipping of the words, then you can set the lines property of your label to 1. Or you want to reduce the font size that also can be done using storyboard property inspector. Hope this will help.
please try this.
my testLabel and number of lines equal to 2.
self.testLabel.lineBreakMode = NSLineBreakByWordWrapping;
self.testLabel.text = #"verificaton process";
I have a whole paragraph and I want to fit it in a label and be justified.Also, I want every line to have a specific range of words. I know that there is "Autoshrink" in Xcode, but it does not seem to work because I am trying it in a multiline text.
Here is an example of what I am trying to do http://imgur.com/Kxbs64Q. You can see how the text is fit into the label and is justified. However, not every line has the same number of characters. Is there a way to compress the text inside the label in swift?.
Use a minimumFontSize for your label. It will allow you to fit all of your text in the label. Also, set your label's numberOfLines to 0 if you want label to automatically create multiple lines. Use this link for help.
I have seen here people needing to calculate the size of the NSString given a size but I need to do the opposite.
Given a specified rect (or fixed UITextView, or multiline UILabel, no scrolling) I need to know:
if it managed to show all the chars of my NSString
if not, what is the last char shown
So that I can display the remaining text in another UITextView (of course if I could use a single UITextView I would not have this problem).
At first it seems a simple thing to do, but actually I am not finding a way, intuitively I think I could use either UITextView's:
textView.contentSize.height;
or NSString's:
sizeWithFont:constrainedToSize:lineBreakMode:
or a combination of the two, but I need to be precise and those methods do not help me in telling what is the last character that managed to fit the visible area of the UITextView.
Not sure if this is actually possible, but is a requirement of my client who thinks programming iOS is like printing a newspaper and expects to be able to format text around an image....
You could maybe get the maximum height of one line of text from a one character long string.
If you use that with sizeWithFont:constrainedToSize:lineBreakMode: then you should be able to know if your text runs onto more than one line (if the cgsize height is greater than the height of one line of text).
In order to find out the last character (or word) you would have to loop around the length of the string adding characters (or words) as you go and checking for when the cgsize height increases to add a new line, this will give you the character point when to split into multiple strings ( for multiple fields/labels/textviews ) or when to insert line breaks into the text ( if using a single multi-line textview or label ).
I hope you find an easier way...
