Same problem if I use align in here to justify text

I don't know why this happened to me. Please give me some instruction for fix it. Any help would be great appreciated

Answer 1

It seems like a bug of UILabel,but you can fix it with a tiny change in your storyboard.
Click the more button in the same line of NSTextAlignments,add a little Head Indent ,such as 0.1 .

Your UILabel will work just fine.

Answer 2

This should work. Here is what I get from the simulator:

What I've done:

1. Drag & drop an UILabel on the storyboard and add some constrains, and colours as well.
2. Set the text as "attributed"
3. Put your text in the text field.
4. Click on justify.
5. Change the police
6. Numbers of lines 0.

At this point you should have this:

Now from the storyboard to your controller add an IBOutlet (Ctrl + drag it to the top of your controller). It should be like this:

Now add some code in your viewDidLoad fct:

let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.alignment = NSTextAlignment.Justified

        let attributedString = NSAttributedString(string: label.text!, attributes: [ NSParagraphStyleAttributeName: paragraphStyle, NSBaselineOffsetAttributeName: NSNumber(float: 0)
            ])

        label.attributedText = attributedString
        label.numberOfLines = 0

The last thing to do is to run your simulator to see if it does what you are expected:

P.S: With xCode 7.2 works definitely. It works for me on both version.
