您可以通過以這種方式覆蓋UIViewController
touchesBegan
方法來簡單地實現這一點:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
guard let touch = touches.first else { return }
let touchLocation = touch.location(in: self.view) // Get the location of the touch
let image = UIImage(named: "anImage") // Create a UIImage instance
let imageView = UIImageView(image: image) // Create a UIImageView with your image
imageView.contentMode = .scaleAspectFit
// Set the position of your image to be where the user touched
imageView.frame = CGRect(x: touchLocation.x,
y: touchLocation.y,
width: 100,
height: 100)
self.view.addSubview(imageView) // Add the image to the view
}
