Changing Text of Uibutton Programmatically Swift

Changing text of UIButton programmatically swift

In Swift 3, 4, 5:

button.setTitle("Button Title", for: .normal)

Otherwise:

button.setTitle("Button Title", forState: UIControlState.Normal)

Also an @IBOutlet has to declared for the button.

How to change font of UIButton with Swift

Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.

myButton.titleLabel?.font =  UIFont(name: YourfontName, size: 20)

However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.

Swift 3 changing the title of a UIButton

Your button needs to be an IBOutlet rather than an IBAction. When you ctrl-drag from Interface Builder to your code, make sure you select the 'Outlet' option as shown below:

Then you can change the button title like this:

else {
    startButton.setTitle("Button Title", for: .normal)
    stopFuncs = true
}

is it possible to update UIButton title/text programmatically?

Do you have the button specified as an IBOutlet in your view controller class, and is it connected properly as an outlet in Interface Builder (ctrl drag from new referencing outlet to file owner and select your UIButton object)? That's usually the problem I have when I see these symptoms.

Edit: While it's not the case here, something like this can also happen if you set an attributed title to the button, then you try to change the title and not the attributed title.

Programmatically change button text

it should be like this :

For Objective C :

[_button setTitle:@"example text" forState:UIControlStateNormal];

For Swift :

_button.setTitle("example Text", forState: UIControlState.Normal)

How to change UIButton state programmatically in Swift

I think you're confused. UIControlState is used to set up target/actions, or to change the appearance of the button for specific states (So, for example, you can specify the image that's used when it's selected, and a different image for when the button is not in the selected state.)

If you want to change the state to selected, you just set the selected property.

button.isSelected = true

Likewise for isEnabled:

button.isEnabled = false //disable the button

Why is UIButton.titleLabel?.text always switching back after I changed it in Swift 5 (UIKit)?

It seems, UIButton does not allow to configure text or color of titleLabel.

From apple doc.s

Do not use the label object to set the text color or the shadow color.
Instead, use the setTitleColor(:for:) and setTitleShadowColor(:for:)
methods of this class to make those changes. To set the actual text of
the label, use setTitle(_:for:) (button.titleLabel.text does not let
you set the text).

Change a UIButton's text (padding) programmatically in Swift

Still valid for:
iOS 12/Xcode 10/Swift 4.2/OSX 10.13.2

iOS 9.1/Xcode 7.1/Swift 2.1/OSX 10.10.5:

The method titleEdgeInsets didn't work for me. My button's frame tightly hugs the text (I didn't specify a frame size), and the frame has a red background color. After doing:

 myButton.titleEdgeInsets = UIEdgeInsetsMake(10,10,10,10)

the red background shrunk inwards by 10 pixels on each side, which meant that now some of the text was outside the red background. Using negative values had no effect on the original frame size.

I was able to get padding around the text, effectively making the frame bigger, by doing:

myButton.contentEdgeInsets = UIEdgeInsetsMake(5,5,5,5)
