How do you add multi-line text to a UIButton?

Question

I have the following code...

UILabel *buttonLabel = [[UILabel alloc] initWithFrame:targetButton.bounds];
buttonLabel.text = @"Long text string";
[targetButton addSubview:buttonLabel];
[targetButton bringSubviewToFront:buttonLabel];

...the idea being that I can have multi-line text for the button, but the text is always obscured by the backgroundImage of the UIButton. A logging call to show the subviews of the button shows that the UILabel has been added, but the text itself cannot be seen. Is this a bug in UIButton or am I doing something wrong?

Note for this very very old QA, in modern Xcode **VERY SIMPLY, CHOOSE "ATTRIBUTED TEXT"** and then it's trivial, select "character wrap". — Fattie, Dec 07 '16 at 15:05

For iOS 6 and above, use the following to allow multiple lines:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
// you probably want to center it
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if you want to 
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

For iOS 5 and below use the following to allow multiple lines:

button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
// you probably want to center it
button.titleLabel.textAlignment = UITextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

2017, for iOS9 forward,

generally, just do these two things:

choose "Attributed Text"
on the "Line Break" popup select "Word Wrap"

Note that, if you want to use AutoLayout, `UIButton` has a bug that prevents the intrinsic content size to work properly with edge insets. To fix that, please refer to http://stackoverflow.com/questions/17800288/autolayout-intrinsic-size-of-uibutton-does-not-include-title-insets where a good solution is presented. – DrMickeyLauer Aug 15 '16 at 10:51
For your record, using a multi-line title label with an attributed string needs creating constraints to wrap perfectly this text inside the button: it's not as easy as a simple string. – XLE_22 Jul 02 '19 at 07:26

I had an issue with auto-layout, after enabling multi-line the result was like this:

so the titleLabel size doesn't affect the button size
I've added Constraints based on contentEdgeInsets (in this case contentEdgeInsets was (10, 10, 10, 10)
after calling makeMultiLineSupport():

hope it helps you (swift 5.0):

extension UIButton {

    func makeMultiLineSupport() {
        guard let titleLabel = titleLabel else {
            return
        }
        titleLabel.numberOfLines = 0
        titleLabel.setContentHuggingPriority(.required, for: .vertical)
        titleLabel.setContentHuggingPriority(.required, for: .horizontal)
        addConstraints([
            .init(item: titleLabel,
                  attribute: .top,
                  relatedBy: .greaterThanOrEqual,
                  toItem: self,
                  attribute: .top,
                  multiplier: 1.0,
                  constant: contentEdgeInsets.top),
            .init(item: titleLabel,
                  attribute: .bottom,
                  relatedBy: .greaterThanOrEqual,
                  toItem: self,
                  attribute: .bottom,
                  multiplier: 1.0,
                  constant: contentEdgeInsets.bottom),
            .init(item: titleLabel,
                  attribute: .left,
                  relatedBy: .greaterThanOrEqual,
                  toItem: self,
                  attribute: .left,
                  multiplier: 1.0,
                  constant: contentEdgeInsets.left),
            .init(item: titleLabel,
                  attribute: .right,
                  relatedBy: .greaterThanOrEqual,
                  toItem: self,
                  attribute: .right,

                  constant: contentEdgeInsets.right)
            ])
    }

}

Works perfect in swift 5. I also added my function to center text in button. func centerTextInButton() { guard let titleLabel = titleLabel else { return } titleLabel.textAlignment = .center } — ShadeToD, Sep 18 '19 at 14:15
I found adding constraint is not necessary, just set the text after lineBreakMode/textAlignment/numberOfLines are set. And also set titleEdgeInsets for top and bottom inset. — Bill Chan, Mar 04 '20 at 18:25
As written, these constraints result in auto-layout conflict every time. Although I am not yet 100% sure of the importance of the use of inequality constraints, I do know that 2 of the constraints are written incorrectly: the bottom and right edges should use `relatedBy: .lessThanOrEqual` and flip the constant negative `constant: -contentEdgeInsets.{bottom|right}` — androidguy, Jul 05 '20 at 06:11
Thank you - I had a `...` in the last line due to an invisible character so I have added `.lineBreakMode = .byClipping` — user2330482, Jul 23 '20 at 22:13

In Xcode 9.3 you can do it by using storyboard like below,

You need to set button title textAlignment to center

button.titleLabel?.textAlignment = .center

You don't need to set title text with new line (\n) like below,

button.setTitle("Good\nAnswer",for: .normal)

Simply set title,

button.setTitle("Good Answer",for: .normal)

First of all, you should be aware that UIButton already has a UILabel inside it. You can set it using –setTitle:forState:.

The problem with your example is that you need to set UILabel's numberOfLines property to something other than its default value of 1. You should also review the lineBreakMode property.

To fix title label's spacing to the button, set titleEdgeInsets and other properties before setTitle:

    button.titleLabel?.lineBreakMode = .byWordWrapping
    button.titleLabel?.numberOfLines = 0
    button.titleEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 20, right: 20)
    button.setTitle("Dummy button with long long long long long long long long title", for: .normal)

Setting lineBreakMode to NSLineBreakByWordWrapping (either in IB or code) makes button label multiline, but doesn't affect button's frame.

If button has dynamic title, there is one trick: put hidden UILabel with same font and tie it's height to button's height with layout; when set text to button and label and autolayout will make all the work.

Note

Intrinsic size height of one-line button is bigger than label's, so to prevent label's height shrink it's vertical Content Hugging Priority must be greater than button's vertical Content Compression Resistance.

These days, if you really need this sort of thing to be accessible in interface builder on a case-by-case basis, you can do it with a simple extension like this:

extension UIButton {
    @IBInspectable var numberOfLines: Int {
        get { return titleLabel?.numberOfLines ?? 1 }
        set { titleLabel?.numberOfLines = newValue }
    }
}

Then you can simply set numberOfLines as an attribute on any UIButton or UIButton subclass as if it were a label. The same goes for a whole host of other usually-inaccessible values, such as the corner radius of a view's layer, or the attributes of the shadow that it casts.

As to Brent's idea of putting the title UILabel as sibling view, it doesn't seem to me like a very good idea. I keep thinking in interaction problems with the UILabel due to its touch events not getting through the UIButton's view.

On the other hand, with a UILabel as subview of the UIButton, I'm pretty confortable knowing that the touch events will always be propagated to the UILabel's superview.

I did take this approach and didn't notice any of the problems reported with backgroundImage. I added this code in the -titleRectForContentRect: of a UIButton subclass but the code can also be placed in drawing routine of the UIButton superview, which in that case you shall replace all references to self with the UIButton's variable.

#define TITLE_LABEL_TAG 1234

- (CGRect)titleRectForContentRect:(CGRect)rect
{   
    // define the desired title inset margins based on the whole rect and its padding
    UIEdgeInsets padding = [self titleEdgeInsets];
    CGRect titleRect = CGRectMake(rect.origin.x    + padding.left, 
                                  rect.origin.x    + padding.top, 
                                  rect.size.width  - (padding.right + padding.left), 
                                  rect.size.height - (padding.bottom + padding].top));

    // save the current title view appearance
    NSString *title = [self currentTitle];
    UIColor  *titleColor = [self currentTitleColor];
    UIColor  *titleShadowColor = [self currentTitleShadowColor];

    // we only want to add our custom label once; only 1st pass shall return nil
    UILabel  *titleLabel = (UILabel*)[self viewWithTag:TITLE_LABEL_TAG];


    if (!titleLabel) 
    {
        // no custom label found (1st pass), we will be creating & adding it as subview
        titleLabel = [[UILabel alloc] initWithFrame:titleRect];
        [titleLabel setTag:TITLE_LABEL_TAG];

        // make it multi-line
        [titleLabel setNumberOfLines:0];
        [titleLabel setLineBreakMode:UILineBreakModeWordWrap];

        // title appearance setup; be at will to modify
        [titleLabel setBackgroundColor:[UIColor clearColor]];
        [titleLabel setFont:[self font]];
        [titleLabel setShadowOffset:CGSizeMake(0, 1)];
        [titleLabel setTextAlignment:UITextAlignmentCenter];

        [self addSubview:titleLabel];
        [titleLabel release];
    }

    // finally, put our label in original title view's state
    [titleLabel setText:title];
    [titleLabel setTextColor:titleColor];
    [titleLabel setShadowColor:titleShadowColor];

    // and return empty rect so that the original title view is hidden
    return CGRectZero;
}

I did take the time and wrote a bit more about this here. There, I also point a shorter solution, though it doesn't quite fit all the scenarios and involves some private views hacking. Also there, you can download an UIButton subclass ready to be used.

You probably need just add uibutton.TitleLabel.TranslatesAutoresizingMaskIntoConstraints = false; as you added it to uibutton itself. (Sorry for c#, I think you can translate it easily). So uibutton.LineBreakMode = UILineBreakMode.WordWrap; will enable multiline text. Because that constraints will bring you problems when you will want to add image or something else in your button.

Based on @Amir Khorsandi answer - but in case you have a button with some image:

extension UIButton {

    func enableMultiline() {
        setContentHuggingPriority(.defaultLow, for: .vertical) // high hugging priority could squeeze the button to 1 line
        titleLabel?.numberOfLines = 0
        titleLabel?.setContentCompressionResistancePriority(.required, for: .vertical)
        titleLabel?.topAnchor.constraint(greaterThanOrEqualTo: topAnchor).isActive = true
        titleLabel?.bottomAnchor.constraint(lessThanOrEqualTo: bottomAnchor).isActive = true
        imageView?.setContentCompressionResistancePriority(.required, for: .horizontal) // otherwise image could be squeezed
    }

}

Although it's okay to add a subview to a control, there's no guarantee it'll actually work, because the control might not expect it to be there and might thus behave poorly. If you can get away with it, just add the label as a sibling view of the button and set its frame so that it overlaps the button; as long as it's set to appear on top of the button, nothing the button can do will obscure it.

In other words:

[button.superview addSubview:myLabel];
myLabel.center = button.center;

Please, if you suggest this kind of ugly approach at least don't make mistakes in your code example :). The label shouldn't have the same center as button if it's a subview. Use myLabel.frame = button.bounds; or myLabel.center = cgPointMake(button.frame.size.with*0.5,button.frame.size.height*0.5) – JakubKnejzlik Aug 06 '14 at 14:53

@GrizzlyNetch I'm specifically advising *not* to add it as a subview of the button. `addSubview:` here adds it to `button`'s superview, thus making it a sibling of the button, so matching their centers is correct. – Becca Royal-Gordon Aug 08 '14 at 06:49
Ah, my mistake! You are right, I've missed the "small" fact it's in the superview :D ... sorry :) – JakubKnejzlik Aug 08 '14 at 08:16
That it is not exactly what is asked, this solution would be a bad way to implement the question since the element button has a title. – Pablo Blanco Jul 17 '19 at 07:21

This was reasonable advice in iPhone OS 2.0. There are much better ways to do it by now. :^) – Becca Royal-Gordon Jul 23 '19 at 05:58
