Swift 3 游戏按钮按下循环

Question

如果我按下按钮，图像将随机出现，我有一组图像。并且有一个图像也从数组中调用，但它只是在我打开游戏时随机出现。我想为按下的按钮做一个条件语句。就像单击按钮后我有 5 个条件： 1- 如果按下并且出现的图像与 UIIMage 视图不同，则会添加向下分数 2-如果按钮没有按下 2 秒钟将出现向下。 3-如果按下按钮并且它与 UIimage 相同，则游戏结束。 4- 如果他因为在 2 秒内没有击中图像而计算出 4 张图像，他将输掉。

 var array:[UIImage] = [UIImage(named: "1.png")!,
                            UIImage(named: "2.png")!,
                            UIImage(named: "3.png")!,
                            UIImage(named: "4.png")!,
                            UIImage(named: "5.png")!,
                            UIImage(named: "6.png")!,
                            UIImage(named: "7.png")!,
                            UIImage(named: "8.png")!,
                            UIImage(named: "9.png")!,
                            UIImage(named: "10.png")!]

var random = arc4random_uniform(10)

@IBAction func myButtonPressed(button: UIButton) {

    var randomNum: UInt32 = 10
    randomNum = arc4random_uniform(UInt32(array.count))

    myButton.setImage(UIImage(named: "bird\(randomNum).png"), for: UIControlState.normal)

    // myButton.setImage(UIImage(named: "\(randomNum).png"), for: UI)


    self.myImage.animationImages = array

    let buttonWidth = myButton.frame.width
    let buttonHeight = myButton.frame.height

    // Find the width and height of the enclosing view
    let viewWidth = myButton.superview!.bounds.width
    let viewHeight = myButton.superview!.bounds.height

    // Compute width and height of the area to contain the button's center
    let xwidth = viewWidth - buttonWidth
    let yheight = viewHeight - buttonHeight

    // Generate a random x and y offset
    let xoffset = CGFloat(arc4random_uniform(UInt32(xwidth)))
    let yoffset = CGFloat(arc4random_uniform(UInt32(yheight)))

    // Offset the button's center by the random offsets.
    myButton.center.x = xoffset + buttonWidth / 2
    myButton.center.y = yoffset + buttonHeight / 2

   /* for i in array{

        if myButton != myImage{
            randomNum = arc4random_uniform(UInt32(array.count))

        }

        if else

    } */

也许你可以尝试这样的事情。至于您的第一个条件，您的 UIImage 视图变量是什么。它是故事板上显示的另一个 UIImage 视图吗？

import UIKit

class ViewController: UIViewController {

    var array: [UIImage] = [UIImage(named: "1.png")!,
                            UIImage(named: "2.png")!,
                            UIImage(named: "3.png")!,
                            UIImage(named: "4.png")!,
                            UIImage(named: "5.png")!]



    @IBOutlet weak var myButton: UIButton!
    var pressed: Bool = false;
    var score: Int = 0;


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        //2nd Condition: if button did not press for 2 seconds will appear down
        if(pressed == false){
            Timer.scheduledTimer(timeInterval: 0.2, target: self, selector: #selector(ViewController.doSomething), userInfo: nil, repeats: true)
        }


    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func isPressed(_ sender: UIButton) {

        pressed = true;

        var randomNum: UInt32 = 10
        randomNum = arc4random_uniform(UInt32(array.count));

        myButton.setImage(UIImage(named: "\(randomNum).png"), for: .normal)

        // 1st Condition: if pressed and the image appeared is not same as the UIIMage view down score will be added
        if( UIImage(named: "\(randomNum).png") != myButton.currentImage){

            //Add View Down Score
            score += 1;
        }
        // 3rd Condition: if button pressed and it is same as the UIimage so game over
        else{

            // Game Over
        }



    }

    func doSomething() {
        // Not sure what you mean by will appear down
        print("Action")
    }

}

我不太确定你的第四个条件是什么。请澄清
