Question

I can’t set the title of UIButton using IB as center. My title is multi line.
It is giving like this one

But I want like this one

I have given space in this but I don’t want to do that. As it is not aligned exactly for some cases and I know there is a property of UILabel to set the alignment but I don’t want to write a code for that.. just want to set everything from IB.

Thanks

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 = .Center
btn.titleLabel.numberOfLines = 0

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
