How to Add Multi-Line Text to a Uibutton

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

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:

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

Swift - UIButton with two lines of text

There are two questions.

I was wondering if it is possible to create a UIButton with two lines
of text

This is possible through using the storyboard or programmatically.

Storyboard:

Change the 'Line Break Mode' to Character Wrap or Word Wrap and use Alt/Option + Enter key to enter a new line in the UIButton's Title field.

Programmatically:

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        btnTwoLine?.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping;
}

I need each line to have a different font size
1

The worst case is, you can use a custom UIButton class and add two labels within it.

The better way is, make use of NSMutableAttributedString. Note that,this can be achieved through only programmatically.

Swift 5:

@IBOutlet weak var btnTwoLine: UIButton?

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    //applying the line break mode
    textResponseButton?.titleLabel?.lineBreakMode = NSLineBreakMode.byWordWrapping;
    let buttonText: NSString = "hello\nthere"

    //getting the range to separate the button title strings
    let newlineRange: NSRange = buttonText.range(of: "\n")

    //getting both substrings
    var substring1 = ""
    var substring2 = ""

    if(newlineRange.location != NSNotFound) {
        substring1 = buttonText.substring(to: newlineRange.location)
        substring2 = buttonText.substring(from: newlineRange.location)
    }

    //assigning diffrent fonts to both substrings
    let font1: UIFont = UIFont(name: "Arial", size: 17.0)!
    let attributes1 = [NSMutableAttributedString.Key.font: font1]
    let attrString1 = NSMutableAttributedString(string: substring1, attributes: attributes1)

    let font2: UIFont = UIFont(name: "Arial", size: 11.0)!
    let attributes2 = [NSMutableAttributedString.Key.font: font2]
    let attrString2 = NSMutableAttributedString(string: substring2, attributes: attributes2)

    //appending both attributed strings
    attrString1.append(attrString2)

    //assigning the resultant attributed strings to the button
    textResponseButton?.setAttributedTitle(attrString1, for: [])
}

Older Swift

@IBOutlet weak var btnTwoLine: UIButton?

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        //applying the line break mode
        btnTwoLine?.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping;

        var buttonText: NSString = "hello\nthere"

        //getting the range to separate the button title strings
        var newlineRange: NSRange = buttonText.rangeOfString("\n")

        //getting both substrings
        var substring1: NSString = ""
        var substring2: NSString = ""

        if(newlineRange.location != NSNotFound) {
            substring1 = buttonText.substringToIndex(newlineRange.location)
            substring2 = buttonText.substringFromIndex(newlineRange.location)
        }

        //assigning diffrent fonts to both substrings
        let font:UIFont? = UIFont(name: "Arial", size: 17.0)
        let attrString = NSMutableAttributedString(
            string: substring1 as String,
            attributes: NSDictionary(
                object: font!,
                forKey: NSFontAttributeName) as [NSObject : AnyObject])

        let font1:UIFont? = UIFont(name: "Arial", size: 11.0)
        let attrString1 = NSMutableAttributedString(
            string: substring2 as String,
            attributes: NSDictionary(
                object: font1!,
                forKey: NSFontAttributeName) as [NSObject : AnyObject])

        //appending both attributed strings
        attrString.appendAttributedString(attrString1)

        //assigning the resultant attributed strings to the button
        btnTwoLine?.setAttributedTitle(attrString, forState: UIControlState.Normal)

    }

Output

2 line text UIButton

Objectivc-C

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.numberOfLines = 2;
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if u need

else use this

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.textAlignment = NSTextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

Swift

button.titleLabel!.lineBreakMode = .ByWordWrapping
button.titleLabel!.numberOfLines = 2
button.titleLabel!.textAlignment = .Center

else use this

button.titleLabel!.lineBreakMode = .ByWordWrapping
button.titleLabel!.textAlignment = .Center
button.setTitle("Line1\nLine2", forState: .Normal)

Swift3

buttonName.titleLabel!.lineBreakMode = .byWordWrapping
buttonName.titleLabel!.textAlignment = .center
buttonName.setTitle("Line1\nLine2", for: .normal)

UIButton with multi-line titleLabel in InterfaceBuilder

Code:

To allow multiple line you can use:

button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
button.titleLabel.textAlignment = UITextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

In iOS 6, UILineBreakModeWordWrap and UITextAlignmentCenter are deprecated, so use:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.textAlignment = NSTextAlignmentCenter;

Interface Builder:

• In interface builder select UIButton
• on the right side Utilities pane under Attributes Inspector, you'll see an option for Line Break
• Choose Word Wrap

Multiple Lines in UIButton

The UIButton displays it's text with a contained UILabel. The default for the contained label is to display one line of text only. This label is accessible through the titleLabel property, and anything you can do to a normal label can be done to it.

For example making it multi-lines broken by words:

ObjC:

myButton.titleLabel.numberOfLines = 0; // Dynamic number of lines
myButton.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;

Swift:

myButton.titleLabel?.numberOfLines = 0; // Dynamic number of lines
myButton.titleLabel?.lineBreakMode = .byWordWrapping;

How do you add multi-line text to a Button in SwiftUI?

You can use Button method lineLimit(_:)

struct ContentView : View {
    var body: some View {
          Button("Hello World").lineLimit(nil)
    }
}

Center Multi-Line Text on UIButton using IB

You can't set the text to be centered in your nib. But you can change the alignment in your code:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.myButton.titleLabel.textAlignment = UITextAlignmentCenter;
}

Multiline NSAttributed String as UIButton Title

You can do it this way:

let dict1 = [NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue]

let attString = NSMutableAttributedString()
attString.appendAttributedString(NSAttributedString(string: "Patient Name\n", attributes: dict1))
attString.appendAttributedString(NSAttributedString(string: "click for patient info", attributes: nil))
startVisitButton.setAttributedTitle(attString, forState: .Normal)
startVisitButton.titleLabel?.numberOfLines = 0
startVisitButton.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping

And result will be:
