Unexpected behaviour with UILabel.numberOfLines = 0

[Mackarous]

I have a TZStackView hierarchy with a bunch of UILabels in it. They have numberOfLines = 0. The problem is that if I attempt the same code with UIStackView on iOS 9, or TZStackView on iOS 9, the UILabels wrap. However with TZStackView on iOS 8.x, the UILabel is ellipsized. Any thoughts on this?

Have you tried something like that?

class MultilineLabelThatWorks : UILabel {
  override func layoutSubviews() {
    super.layoutSubviews()
    preferredMaxLayoutWidth = bounds.width
    super.layoutSubviews()
  }
}

@fabb I am doing that as a workaround (without subclassing, I think that's overkill), but the issue is that on iOS 9 with a UIStackView, setting the preferredMaxLayoutWidth is not necessary

[fabb]

No issue, just juse an #available macro.

Well the issue is it is no longer a drop in replacement, but I guess it'll have to do.

This is strange. Can you try to compare the constraints generated on UIStackView and on TZStackView as well as the constraints added to your UILabels? There should be a difference, and if there is: this is a bug and I will try to fix it.

Hm, you're right, preferredMaxLayoutWidth = 0 should be supported since iOS 8. For iOS 7 the workaround would be necessary.

Going to close this one out for inactivity
