How to make UIButton's text alignment center? Using IB

This will make exactly what you were expecting:

Objective-C:

 [myButton.titleLabel setTextAlignment:UITextAlignmentCenter];

For iOS 6 or higher it's

 [myButton.titleLabel setTextAlignment: NSTextAlignmentCenter];

as explained in tyler53's answer

Swift:

myButton.titleLabel?.textAlignment = NSTextAlignment.Center

Swift 4.x and above

myButton.titleLabel?.textAlignment = .center

Use the line:

myButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

This should center the content (horizontally).

And if you want to set the text inside the label to the center as well, use:

[labelOne setTextAlignment:UITextAlignmentCenter];

If you want to use IB, I've got a small example here which is linked in XCode 4 but should provide enough detail (also mind, on top of that properties screen it shows the property tab. You can find the same tabs in XCode 3.x):

You can set the key path in the storyboard

Set the text to your multiline title e.g. hello ⌥ + ↵ multiline

You need to press ⌥ + ↵ to move text to next line.

Then add the key path

titleLabel.textAlignment as Number and value 1, 1 means NSTextAlignmentCenter
titleLabel.numberOfLines as Number and value 0, 0 means any number of lines

This will not be reflected on IB/Xcode, but will be in centre at run time (device/simulator)

If you want to see the changes on Xcode you need to do the following: (remember you can skip these steps)

1. Subclass the UIButton to make the button designable:

   import UIKit@IBDesignable class UIDesignableButton: UIButton {}

2. Assign this designable subclass to the buttons you're modifying:

3. Iff done right, you will see the visual update in IB when the Designables state is "Up to date" (which can take several seconds):

If you want to write the code, then do the long process

1.Create IBOutlet for button
2.Write code in viewDidLoad

btn.titleLabel.textAlignment = .Centerbtn.titleLabel.numberOfLines = 0

Solution3

In newer version of xcode (mine is xcode 6.1) we have property attributed title
Select Attributed then select the text and press centre option below

P.S. The text was not coming multiline for that I have to set the

btn.titleLabel.numberOfLines = 0
