Self sizing cells with three UILabels not working - ios

Question

This is the UITableViewCell I have:
The three UILabels have trailing, top, bottom and leading constraints.
This is the hugging priority and compression resistance priority for the UILabel Name:
This is the hugging priority and compression resistance priority for the UILabel Location:
This is the hugging priority and compression resistance priority for the UILabel Type:
On the viewDidLoad from my UITableViewController I'm doing something like this:
self.tableView.estimatedRowHeight = 80
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.reloadData()
But when I run the app, the UITableViewCells don't self sizing:
What am I doing wrong or what do I need to do to make the UITableViewCells make them self sizing?
Edit
I set to 0 the numberOfLines for each UILabel, now the location UILabel doesn't appear

Answer 1

It is most likely that your Text turned out larger in runtime causing the total height in your cell View to turn out greater than the row height itself.
First equate all the hugging priority and then try changing the spacing distance between the Labels with the relation 'Greater than or Equal' and then set the constant to something small like zero. If you still get a constraint error, increase your tableView row height.
Alternative method:
Add all 3 UILabels into another UIView with spacing zero between them, do not set a height constraint for this UIView and just set it in the centerY of the cellView and spaced from the ImageView
Tip: Only change constraint priorities if your UI is what you want even after the constraints are broken, unless of course you know what you're doing

Answer 2

For ur case no need to vertical hugging priority,just give
label.numberOfLines = 0
that works fine.

Answer 3

The question says you want to resize the label, but based on your code it seems like you want to do it by resizing the tableview rows. If that's the case, the correct place to set row height in a tableView is:
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 80
}
Where "return 80" means you want table rows to be of height 80. Please let me know if I didn't understand your question right.

Answer 4

The label doesn't work because the storyboard is not very useful.
Set the var:
var imageView: UIImageView ={
let image = UIImageView()
image.translatesAutoresizingMaskIntoConstraints = false
return image
}()
var textView: UITextView ={
let text = UITextView()
text.translatesAutoresizingMaskIntoConstraints = false
return text
}()
And you continue with other label.
You have to set constraints like this example:
self.addSubview(imageView)
self.addSubview(textView)
imageView.bottomAnchor.constraintEqualToAnchor(self.bottomAnchor, constant: -10).active=true
imageView.leftAnchor.constraintEqualToAnchor(self.leftAnchor, constant:-10).active=true
imageView.widthAnchor.constraintEqualToConstant(70).active=true
imageView.heightAnchor.constraintEqualToConstant(70).active=true
label.topAnchor.constraintEqualToAnchor(self.topAnchor, constant: -5).active=true
label.leftAnchor.constraintEqualToAnchor(imageView.rightAnchor, constant: 3).active=true
label.widthAnchor.constraintEqualToAnchor(self.widthAnchor, constant -70).active=true
label.heightAnchor.constraintEqualToConstant(30).active=true
label2.topAnchor.constraintEqualToAnchor(label.bottomAnchor, constant: 5).active=true
label2.leftAnchor.constraintEqualToAnchor(imageView.rightAnchor, constant: 3).active=true
label2.widthAnchor.constraintEqualToAnchor(self.widthAnchor, constant -70).active=true
label2.heightAnchor.constraintEqualToConstant(30).active=true
And with this way also for the third label.
