UILabel truncate tail and skip not complete word

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

enter image description here

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

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

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.
