how to programmatically fake a touch event to a UIButton?

📣 Hey tech enthusiasts! 👋 Are you struggling with the challenge of faking a touch event to a UIButton programmatically? 🤔 Don't worry, I've got you covered! In this blog post, I'll help you tackle this problem head-on, providing easy solutions and handy examples along the way. So, let's dive right into it! 💪

🔎 Understanding the Context The question at hand revolves around writing unit tests that require simulating a button press in the UI. While calling the IBAction selector might seem like an option, our goal here is to genuinely mimic a button press event triggered by the user. So, what's the best way to achieve this? 🤷‍♀️

🛠️ Solution: Programmatically Faking a Touch Event To programmatically fake a touch event to a UIButton, you can follow these steps:

1. Access the target object and action of the button:

   let target = button.allTargets.first let action = button.actions(forTarget: target, forControlEvent: .touchUpInside)?.first

2. Invoke the target object's action manually:

   target?.perform(Selector(action))

🎉 Voila! You've successfully faked a touch event to the UIButton programmatically! 🙌

💡 Example: Faking a Button Press Let's see the above solution in action with a practical example. Assume we have a button named "submitButton" in our UI. To simulate a button press, we can use the following code snippet:

let button = UIButton()
button.setTitle("Submit", for: .normal)

// Programmatically faking a touch event
let target = button.allTargets.first
let action = button.actions(forTarget: target, forControlEvent: .touchUpInside)?.first
target?.perform(Selector(action))

Simple, isn't it? This code snippet will fake a touch event to the "submitButton," triggering the button's action as if the user pressed it in the GUI. 🎮
