Programatically Created Label Within Container View Won't Expand For Text












1















I have a reusable view class, with the function .addDisapearingView() when added to another view displays the text in the functions parameters. Both the label and its container view are programmatically created. When there's long text in the label, I want the label, and the view to both grow in height. When there's text too long for the label, the label doesn't grow-and the text, subsequently, doesn't clip/go to next line. I'm trying to get the container view to expand programmatically based upon the text.



I've tried an extension that detects when the label is truncated. Using that extension, I used the += operator on the label and view to expand both of them with no luck.



while label.isTruncated {
print("printing while truncating in the while loop")
regView.frame.size.height += 5
label.frame.size.height += 5
}


The interesting thing with that is, I've used that code before, with the addition of adding 5 to the height constraint of the view in the storyboard to expand the size of the label for text, and it worked. That lead me to believe that my problem might reside somewhere in editing the height constraint for the regView.



I've tried countless variations of



    label.adjustsFontSizeToFitWidth = true
label.numberOfLines = 3
label.lineBreakMode = .byWordWrapping
label.translatesAutoresizingMaskIntoConstraints = false
label.frame.size.height = regView.frame.size.height
label.sizeToFit()
regView.layoutSubviews()


I've tried changing the frame of the view and label, changing the constaints at the top of the code, and the answers from other questions.



Code:



Truncated Label Extension:



extension UILabel {

var isTruncated: Bool {

guard let labelText = text else {
return false
}

let labelTextSize = (labelText as NSString).boundingRect(
with: CGSize(width: frame.size.width, height: .greatestFiniteMagnitude),
options: .usesLineFragmentOrigin,
attributes: [.font: font],
context: nil).size

return labelTextSize.height > bounds.size.height
}
}


View constraint changer:



extension UIView {

func updateConstraint(attribute: NSLayoutAttribute, constant: CGFloat) -> Void {
if let constraint = (self.constraints.filter{$0.firstAttribute == attribute}.first) {
constraint.constant = constant
self.layoutIfNeeded()
}
}
}


Whole function:

regView.backgroundColor = colorView
regView.alpha = alpha

The interesting thing(That I tried to fix) was that even if the height is set to 40, or a value where two lines of text could fit, the label still doesn't expand/truncate, much less if the height param is 20.

          I guess you completely need auto-layout and make regView expand according to the label's text without any height constraints



          let regView = UIView()

          if #available(iOS 11.0, *) {
          let guide = toview.safeAreaLayoutGuide
          NSLayoutConstraint.activate([

          • Is there a way to animate the height anchor so that when the method is used the view slides down into the superview?

          I guess you completely need auto-layout and make regView expand according to the label's text without any height constraints
