声明var imageview:UIImageView!

在viewDidLoad（）方法中初始化

self.imageview = UIImageView(frame:CGRect(x:20,y:120,width :280,height:280))

imageview.backgroundColor = UIColor.blueColor()

self.view.addSubview(imageview)

//Enable用户交互

self.imageview.userInteractionEnabled =true

//添加手势识别

self.imageview.addGestureRecognizer(UITapGestureRecognizer(target:self,action: "touchSelect:"))

第二步：

添加手势识别方法

func touchSelect(sender:UITapGestureRecognizer)->Void{

print("你点击了我")

}
