在Swift中检测UIImageView Touch [英] Detect UIImageView Touch in Swift

问题描述

触摸 UIImageView 时，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

你可以放一个 UITapGestureRecognizer 在 UIImageView 里面使用Interface Builder或代码（如你所愿），我更喜欢第一个。然后你可以放一个 @IBAction 并处理你的 UIImageView 里面的点击，别忘了设置<$接口生成器或代码中的c $ c> UserInteractionEnabled 到 true 。

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.")
}

我希望这可以帮到你。
