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.

which version of xcode use using? how you achieve it. – Boatbill

Version 7.3 (7D175) but should work as well with version 7.2. Juste one minute, I m typing more info ;) – Trimetric

i'm sure 100% that not work in Xcode Version 7.2 (7C68). i will update Xcode now – Boatbill

i apologize for my confusion. it still happens – Boatbill

@PhanVănLinh: no worries, have a look at my added screenshot. – Trimetric

@KeyMarker00 I have update my post, with my Xcode image – Boatbill

I have to go home now. I will check your update later. Thank you so much for your time – Boatbill

Ah! because it's already justified. If you stretch your label box a bit more you will see that the word "accounts" will be on the first line. – Trimetric

Here is one solution to solve my problem right now. I set the alignment justified for my UILabel programmatically and it work

NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
            paragraph.alignment = NSTextAlignmentJustified;

    NSDictionary *attribute = @{
                                        NSParagraphStyleAttributeName: paragraph,
                                        NSFontAttributeName: self.describesLabel.font,
                                        NSBaselineOffsetAttributeName:[NSNumber numberWithFloat:0]
                                        };
    NSAttributedString *attributeMessage = [[NSAttributedString alloc] initWithString:self.describesLabel.text attributes:attribute];
    self.describesLabel.attributedText = attributeMessage;

Hi Phan. This is the same solution I've given you but yours is in Obj-C. A bit of recognition would be gread ;( – Trimetric

@Trimetric I miss your Swift code. It same my code in Obj-C right?. I don't know swift, sorry for my mistake – Boatbill

Answer 4

Don't use attributed text just use Plain text and select all the text and make it justify. I am facing the same problem fixed it by changing attributed to plain text in Storyboard. If it doesn't work then you have to fix it by code :-

Using Attributed Text:-

 NSMutableParagraphStyle *paragraphStyle = NSMutableParagraphStyle.new;
 paragraphStyle.alignment                = NSTextAlignmentJustified;

 NSDictionary *attrsDictionary           = [NSDictionary dictionaryWithObjectsAndKeys:yourFont,NSFontAttributeName,paragraphStyle,NSParagraphStyleAttributeName, nil];

 NSAttributedString *attributeMessage    = [[NSAttributedString alloc] initWithString:yourTextString attributes:attrsDictionary];
 self.yourLabel.attributedText           = attributeMessage;

Using Plain Text :-

self.yourLabel.textAlignment             = NSTextAlignmentJustified;
self.yourLabel.font                      = yourFont;
self.yourLabel.text                      = yourTextString;

Hope It helps...

You can do it programatically if its not working from storyboard or nib

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
paragraphStyle.alignment = NSTextAlignmentJustified;


NSAttributedString *string = [[NSAttributedString alloc] initWithString:@"Your text here"];
                                                             attributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                                         paragraphStyle, NSParagraphStyleAttributeName ,
                                                                         [NSNumber numberWithFloat:0],NSBaselineOffsetAttributeName,
                                                                         nil]];

self.yourLabel.attributedText = string;
