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.

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.
Here I have a UICollectionViewCell, with a UILabel. My labels are character wrapping long words onto a second line. I thought autoshrink would take precedence over line breaks, since "Cappuccino" can easily be autoshrunk onto just 1 line. I even have Word Wrap on.
Why is this label being character wrapped as opposed to autoshrunk with a minimum font size?
EDIT: I'm aware that numberOfLines needs to be > 0, but programmatically determining numberOfLines based on a label's text and bounding rect doesn't consider autoshrink. I can check if the font size with 1 line != my desired font size, and adjust numberOfLines by guessing, but there's no isTruncated property for me to tell whether the line has broken. So the right question is, how can I programmatically account for autoshrink while determining an appropriate numberOfLines?
you must set a number of lignes > 0 when using this config for all UI text containers.
I want to show the text in uilabel. The text is ,000124520.061112782.,3299985343, I have assign line break mode to character wrap and number of lines to 0. But in label first line is displayed only the , and then other characters are displayed in next line. But i want to display the text in two lines only. But it is displayed in three lines. I don't know why , is displayed in first line. Please anyone help me.
You should set the numberOfLines of your UILabel to 1.
When the numberOfLines property of a UILabel is set to 0 the UILabel will render its text over as many lines as it needs - e.g. its infinite. To fix your text to a single line you should therefore set the property to 1.
Obviously your text may not all fit on a single line so you should also set the UILabel's minimumScaleFactor property to allow the UILabel to adjust its font size downward (to the supplied limit) to fit the content into the frame of the label. You will also need to set the UILabel's adjustsFontSizeToFitWidth property to YES.
Further to the above an easy way to calculate the value for the minimumScaleFactor property is to divide the minimum font size by the maximum font size. So, say for example your label's default font size was 12 and you were happy for it to drop to 10, then assign the minimum scale factor as follows:
myLabel.minimumScaleFactor = 10/12.0f;
I have dynamic text in a label with plenty of room around it. Since there is room, it would be great if the text could wrap in addition to autoshrinking.
You can apply any of these 2 solutions
1.Set numberOfLines To 0 and make larger height of your label then text automatically wrap.
2.you can dynamically calculate height of label on the basis of length of string with function sizeWithFont.
