I need to use subscript and superscript so I have used NSMutableAttributedString to offset specific characters.
I need an equivalent of:
mybutton.titleLabel?.minimumScaleFactor = 0.5
mybutton.titleLabel?.numberOfLines = 0
mybutton.titleLabel?.adjustsFontSizeToFitWidth = true
but for attributed strings?
Any starters much appreciated. Best wishes.

I have a single line UILabel. It has width = screen width and the content now is (the content of UILabel can change)
You have 30 seconds to make an impression during an interview
Currently, my UILabel is truncated tail and the word "duration" is not complete
self.nameLabel.lineBreakMode = NSLineBreakByTruncatingTail;
What I want is I want my UILabel still truncating tail and only display complete word.
Like the image below
Any help or suggestion would be great appreciated.
You can do something like this:
let labelWidth = CGRectGetWidth(label.bounds)
let str = "You will have 30 seconds till you give us a good impression" as NSString
let words = str.componentsSeparatedByString(" ")
var newStr = "" as NSString
for word in words{
let statement = "\(newStr) \(word) ..." as NSString
let size = statement.sizeWithAttributes([NSFontAttributeName:label.font])
if size.width < labelWidth {
newStr = "\(newStr) \(word)"
}
else{
break
}
}
newStr = newStr.stringByAppendingString(" ...")
self.label.text = newStr as String
Idea is: we split words and try check the width while appending from the beginning + the string "..." till we found the a word that will exceed the size, in the case we stop and use this new string
Ideally this is not possible,with default UILabel, when you set lineBreakMode to TruncatingTail, depending on the space required by the letter/word the OS will truncate it, one solution to fix the issue you can use following properties depending on your match.
Minimum Font Scale -- Use this property to specify the smallest multiplier for the current font size that yields an acceptable font size to use when displaying the label’s text. If you specify a value of 0 for this property, the current font size is used as the smallest font size.
Minimum Font Size -- When drawing text that might not fit within the bounding rectangle of the label, you can use this property to prevent the receiver from reducing the font size to the point where it is no longer legible.
i am not sure but try it:
nameLabel.adjustsFontSizeToFitWidth = NO;
nameLabel.lineBreakMode = NSLineBreakByWordWrapping;
OR
If you are using storyboard follow these steps i tried this and it working fine
Open Attribute Inspector
Change Line Breaks to Truncate Tail then
Change AutoShrink to Minimum Font Size
here are my screenshots of label after and before applying these properties
new output
I followed a that told to use "TruncatingTail" not "WordWrapping" so I used this. But still not able to find the way to get the best optimal output as attached in image.
lbl.text = "1 Year\n=\n365 Opportunities"
lbl.numberOfLines = 0;
lbl.lineBreakMode = .byTruncatingTail;
lbl.adjustsFontSizeToFitWidth = true;
lbl.minimumScaleFactor = 0.1;
lbl.textAlignment = .center;
lbl.backgroundColor = .red
lbl.font = UIFont.init(name:"SourceCodePro-Regular", size: 80)
lbl.numberOfLines = 0;
lbl.lineBreakMode = .byWordWrapping;
I am building an App for Quotes, but I am stuck at this point. I have tried all various ways but not able to succeed. Please anyone can help so it will be a great help to me.
Thank you.
From the UILabel documentation for lineBreakMode:
Specifies what happens when a line is too long for the label’s bounds. Character wrap and word wrap are most commonly applied to multiline labels and determine the position of line breaks between consecutive lines. Select word wrap to place line breaks at word boundaries, or character wrap to insert line breaks in words. Truncate head, middle, and tail are usually applied for single-line labels, and describe the placement of an inserted ellipsis to represent the truncated text. Access this value at runtime with the lineBreakMode property.
Truncating the tail doesn't apply when you allow as many lines as required (numberOfLines = 0). Switch back to using byWordWrapping and your auto-shrink settings should do the rest.
I have a UITextField that will display floating point values between 0 and 1.0 with 3 digits after the decimal point. So the widest text it will show is something like "0.000". I'd like to set the auto layout width constraint so that the text field always has just enough room to display this value.
The code below is close, but does not work.
let biggestString = "0.000"
let textAttrs = [NSAttributedStringKey.font: myField.font]
let size = (biggestString as NSString).size(withAttributes: textAttrs)
myField.widthAnchor.constraint(equalToConstant: size.width).isActive = true
It ends up displaying "1.0..." I'm guessing this is because a UITextField has some kind of padding around the text, so so I need to set the width to be the string width + the padding. But, I don't see a property from which I can read this padding amount. Is there a way to get it?
Try searching for the 'intrinsicContentSize'. According to the documentation this is what has to be set to indicate to the auto-layout how big the content is.
There was also a more elaborate discussion on how this can actually if the layout settings do not allow the resizing to work, see other question here:
How to increase width of textfield according to typed text?
I have 3 labels next to each other inside a horizontal stack view like this
The first and last label are going to be dynamically filled with a word of variable length, while the middle one is always going to contain the word "with", for example: "Coding with Swift!"
I don't want there to be extra space between each word as it would look strange if the words are short. Is there any way to make the labels only be as wide as they need to be to fit their text? That way it all looks like one label (except I'm making the middle label have smaller text).
Add 3 labels inside a UIView instead of stack view.
And set constraints as shown in image.
How about using autolayout?
You could give a horizontal space of 0 between the labels and a constraint of width for the middle one.
If u wish to have different fonts for the content in a label you can use NSAttributedString
let boldFontDict:[String: AnyObject] = [NSForegroundColorAttributeName : UIColor.black, NSFontAttributeName: <UI Font>]
let 1stString = NSAttributedString(string: "Hello")
let 2ndString = NSAttributedString(string: "hii", attributes: boldFOntDict)
let finalAttrStr = NSMutableAttributedString(attributedString: 1stString)
finalAttrStr.append(2ndString)
myLabel.attributedText = finalAttrStr
You can take one label instead of taking three label
and and set the text on label as
label.text= firstLabel.text + "with" + lastLabel.text
You can use autolayout to fix this problem.
