在 Swift 中检测 UIImageView 触摸

Detect UIImageView Touch in Swift(在 Swift 中检测 UIImageView 触摸)

问题描述

当 UIImageView 被触摸时，您将如何检测并运行操作?这是我到目前为止的代码:

How would you detect and run an action when a UIImageView is touched? This is the code that I have so far:

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) { 
    var touch: UITouch = UITouch()
    if touch.view == profileImage {
        println("image touched")
    }
}

推荐答案

您可以使用 Interface Builder 或在代码中(根据需要)将 UITapGestureRecognizer 放入您的 UIImageView，我更喜欢第一个.然后你可以放一个 @IBAction 并在你的 UIImageView 中处理点击，不要忘记将 UserInteractionEnabled 设置为 true 在 Interface Builder 或代码中.

You can put an UITapGestureRecognizer inside your UIImageView using Interface Builder or in code (as you want), I prefer the first. Then you can put an @IBAction and handle the tap inside your UIImageView, Don't forget to set the UserInteractionEnabled to true in Interface Builder or in code.

@IBAction func imageTapped(sender: AnyObject) {
    println("Image Tapped.")
}
