如何检测快速点击了哪个图像

How to detect which image has been tapped in swift(如何检测快速点击了哪个图像)

问题描述

我在一个 ViewController 上创建了 6 个 UIImageViews，稍后我将向它们添加 TapGestureRecognizers.

I have created 6 UIImageViews on a ViewController, and I am later going to add TapGestureRecognizers to all of them.

我想让它根据点击的图像，打开另一个 ViewController 并显示某些信息.

I want to make it so that depending on what image has been clicked, another ViewController will open and display certain information.

为此，我需要知道点击了哪张图片.我将如何在 Swift 中做到这一点?

For this to happen, I need to know which image has been clicked. How would I do this in Swift?

推荐答案

UIGestureRecognizer 有属性'view' 这个属性是你添加它的视图.对于这个例子，imageView.

UIGestureRecognizer has property 'view' this property is the view you add it to. For this example the imageView.

func tap(gesture: UIGestureRecognizer) {
    println(gesture.view!.tag) // You can check for their tag and do different things based on tag
}

let img = UIImageView()
img.userInteraction = true
img.tag = 0
img.addGestureRecognizer(UITapGestureRecognizer(self, action: "tap:"))
