swift——图片添加点击事件

let taget = UITapGestureRecognizer(target:self, action: "imgAction")

                taget.numberOfTapsRequired = 1

                img.userInteractionEnabled = true

                img.addGestureRecognizer(taget)

//如果带有参数，写一个类

import Foundation

import UIKit

//带有参数得手势识别

class UserInfoTapRecognizer: UITapGestureRecognizer {

    var userInfo: [String: String] = [:]

}
