Changing text of UIButton programmatically swift

Changing text of UIButton programmatically in Swift

So you want to dynamically change the text of a UIButton in Swift, but you’re facing a roadblock. Don't worry, we’ve got you covered! 🎉

The Problem

The code provided in the question, currencySelector.text = "foobar", leads to an "Expected Declaration" error in Xcode. This happens because UIButton doesn't have a text property, unlike UILabel. But fret not! We have an easy solution for you.

The Solution

To change the text of a UIButton programmatically, we need to use the setTitle(_:for:) method provided by UIButton. Here's the updated code:

currencySelector.setTitle("foobar", for: .normal)

By using this method, you can specify different titles for different button states, such as .normal, .highlighted, and .selected. In this case, we are setting the title for the normal state.

Example Usage

Here's an example of how you can implement the setTitle(_:for:) method in your code:

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var currencySelector: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let newTitle = "foobar"
        currencySelector.setTitle(newTitle, for: .normal)
    }
}

In the above code snippet, we assume that you have a UIButton IBOutlet named currencySelector connected to your storyboard or XIB file.
