I have a UILabel. I need to set the number of lines to fit to it's text.
You can set the numberOfLines property to 0, which removes any line limit and uses as many lines as needed.

If you take a close look an an iMessage conversation cell, you’ll notice that the preview text is always two lines long. This can’t be a hard coded row height because the rows adjust to dynamic type. How can you always force a label to take up a certain number of lines even if there isn’t enough text to do so?
Set the label's numberOfLines to 2 and end the label's text with a linefeed \n. Set the wrapping to word wrap to prevent the ellipses from appearing.
This guarantees that the label text consists of at least 2 lines worth of material. Thus it can never be less than 2 lines, and since the maximum number of lines is 2, it can never be more than 2 lines. Thus it will always be (wait for it) 2 lines.
One way I think this could be possible is having a UIView as a parent of the UILabel.
Fix the height of the UIView based on device size class. Let's say for example 50 points for Width = Compact and Height = Regular.
Embed UILabel in UIView
Set number of Lines = 0 for UILabel
Now match UILabel leading , trailing ,top edge with the superview and leave the height as it is , also don't set the bottom constraints.
Select the superview i.e the UIView and UILabel together and select Equal Heights.
Open the constraint window and change label height less than or equal to SuperView height.

I checked there is no properties for multiline in SKLabelNode.
Is it possible to display multiple lines in SKLabelNode?
If no, Please give idea to display text in multilines.
I use this bit of code to get multi lines of code with SKLabelNode.
Multilines in a label-github
There is a way now to do multi-line SKLabelNodes.
Set the property numberOfLines to 0. From Apple's documentation:
The default value is 1 (a single line). A value of 0 in interpreted as an unlimited number of lines. If the height of the text reaches the number of lines, the text will be truncated using the line break mode.
I have a UILabel with some text on it, what I want is if the text with the given font does not fit to the label, I want it to be first linebreaked to a second line, and if still does not fit then it should automatically adjust those 2 lines to a smaller font.
I experienced with the IB changing the settings of linebreaks and number of rows, but couldn't get what I want.
Any recommendadtions?
To my knowledge UILabel does not support auto adjusting the font when there is more than one line.
The only way I know of it to iteratively calculate a fitting font size and then to set the appropriate font manually.
Maybe the sizeWithFont: method is a solution for you:
– sizeWithFont:forWidth:lineBreakMode:
This calculates the width / height of a NSString with the appropriate font / settings
I have a table view that I am customizing and I am adding a UILabel as a subview of the contentView, and I want the number of lines to be relatively consistent.
I set the numberOfLines property to be 3 so it can't go more than that, but there are still some that overflow onto the 4th line.
If it overflows, I want to add a a trailing ...
How can I figure out if it overflows? I've tried truncating at different character counts of my string, but since I am using lineBreakMode = UILineBreakModeWordWrap the number of characters doesn't really predict the number of lines.
Is there a way to find out the number of lines your UILabel is using?
Don't use lineBreakMode = UILineBreakModeWordWrap, just set the numberOfLines property to 3.
I have an NSString and want to fit it into a rectangle. The rectangle has a specified size, lets say width=150 and height=30. When the String is short and has only one character, it can be as high as the rectangle. More specific: It can have a big font size. But if the string has too much characters and would exceed the bounds of the rectangle, it must become smaller. More specific: It's font size must become smaller, so that it won't exceed the bounds of the rectangle. Is there a way of doing that without messing around in core graphics?
For some reason, UILabel's adjustsFontSizeToFitWidth Property has no effect. The text keeps beeing small even if there is plently of space.
I've set that to
label.adjustsFontSizeToFitWidth = YES;
but nothing happens. I hope there is another way to do that...
There are several part to UILabel that make this possible, but first you have to know if you want to truncate the string or make the font size smaller to fit in the rectangle.
For both cases you'll want to set the UILabel's numberOfLines property to 0, allowing the label to wrap as much as necessary. Then you'll want to set the frame of the UILabel to match the rectangle you're looking to fit. From there you take one of two paths:
Truncation: Set the lineBreakMode property to UILineBreakModeClip, UILineBreakModeHeadTruncation, UILineBreakModeTailTruncation, or UILineBreakModeMiddleTruncation depending on the truncation behavior you're looking for.
Resizing: Set the lineBreakMode to either UILineBreakModeWordWrap or `UILineBreakModeCharacterWrap' depending on your preference. Then you'll need to enter a loop to figure out the right font size. Start with a reasonable font size (e.g., 12) and:
Set the font property of the UILabel with a UIFont that matches that size
Call - (void) sizeToFit for the UILabel.
Check the frame for the UILabel:
If the frame will fit within the bounds you need it to, you're done
If the frame is still to big, drop the size of the font and repeat the loop
For the latter option you'll want to make sure you're not squeezing the text into oblivion, so you'll want to put a minimum size cap on the font size.
You can get more information from the UILabel and UIFont documentation.
adjustsFontSizeToFitWidth adjusts the font size down, not up.
Set the font on your UILabel to an appropriately large size, and UILabel will shrink it when necessary to fit in its bounds.
Set label font size to desired normal size.
Set label minimum font size to
smallest possible font
(minimumFontSize property)
Set adjustsFontSizeToFitWidth to
YES.
If you need multiple lines, set lineCount to 0 as the other poster noted.
