xcode – 如何使UIImageView可以兼容并使其执行某些 *** 作？ (迅速)

概述(我刚开始使用Swift几天前对编程比较新,所以请耐心等待.)我试图在屏幕上显示随机块,用户必须点击它们才能使它们消失.我已经能够创建块,但我不知道如何实际使它们可以应用.有人可以帮帮我吗？到目前为止这是我的代码： func createBlock(){ let imageName = "block.png" let image = UIImage(named: imageNam (我刚开始使用Swift几天前对编程比较新,所以请耐心等待.)我试图在屏幕上显示随机块,用户必须点击它们才能使它们消失.我已经能够创建块,但我不知道如何实际使它们可以应用.有人可以帮帮我吗？到目前为止这是我的代码：

func createBlock(){    let imagename = "block.png"    let image = UIImage(named: imagename)    let imageVIEw = UIImageVIEw(image: image!)    imageVIEw.frame = CGRect(x: xposition,y: -50,wIDth: size,height: size)    self.vIEw.addSubvIEw(imageVIEw)    UIVIEw.animateWithDuration(duration,delay: delay,options: options,animations: {        imageVIEw.backgroundcolor = UIcolor.redcolor()        imageVIEw.frame = CGRect(x: self.xposition,y: 590,wIDth: self.size,height: self.size)        },completion: { animationFinished in            imageVIEw.removeFromSupervIEw()    })}

这是新代码：

func createBlock(){    let imagename = "block.png"    let image = UIImage(named: imagename)    let imageVIEw = UIImageVIEw(image: image!)    imageVIEw.frame = CGRect(x: xposition,height: size)    self.vIEw.addSubvIEw(imageVIEw)    imageVIEw.userInteractionEnabled = true    let tapRecognizer = UITapGestureRecognizer(target: self,action: Selector("imageTapped"))    imageVIEw.addGestureRecognizer(tapRecognizer)    func imageTapped(gestureRecognizer: UITapGestureRecognizer) {        let tappedImageVIEw = gestureRecognizer.vIEw!        tappedImageVIEw.removeFromSupervIEw()        score += 10    }    UIVIEw.animateWithDuration(duration,animations: {        imageVIEw.backgroundcolor = UIcolor.redcolor()        imageVIEw.frame = CGRect(x: self.xposition,completion: { animationFinished in            imageVIEw.removeFromSupervIEw()    })}

解决方法 创建视图后,需要将其userInteractionEnabled属性设置为true.然后你需要附加一个手势.

imageVIEw.userInteractionEnabled = true//Now you need a tap gesture recognizer//note that target and action point to what happens when the action is recognized.let tapRecognizer = UITapGestureRecognizer(target: self,action: Selector("imageTapped:"))//Add the recognizer to your vIEw.imageVIEw.addGestureRecognizer(tapRecognizer)

现在你仍然需要这个函数,在这种情况下是imageTapped：,这是识别手势时动作发生的地方.已识别的手势将作为参数发送,您可以从手势视图属性中找出从哪个图像视图中点击.

func imageTapped(gestureRecognizer: UITapGestureRecognizer) {    //tappedImageVIEw will be the image vIEw that was tapped.    //dismiss it,animate it off screen,whatever.    let tappedImageVIEw = gestureRecognizer.vIEw!}
