Question

我对swift相对较新，而且我正在开发一款游戏，当点击屏幕上的随机位置时，UIView会移动。问题是我每次尝试在执行UIView的所有动画的IBAction中添加新代码它弄乱了动画。这是我的相关代码：

import UIKit

class ViewController: UIViewController {

@IBOutlet var bottomConstraint: UIView!

@IBOutlet var topConstraint: UIView!

@IBOutlet var square: UIView!

@IBOutlet var SecondsScore: UILabel!

var timer: NSTimer!

var incrementA = 0.0

//====================FunctionA========================//


override func viewDidLoad() {
    super.viewDidLoad()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        timer?.invalidate()
}

//======================Actions========================//

@IBAction func squareTapped(tapped: UITapGestureRecognizer) {
    SecondsScore.text = "\(++incrementC)" //HERE IS THE CODE I ADD AND IT CHANGES THE ANIMATION OF THE UIVIEW
    animateSlide()
    timeIntervalForSquare()
}

@IBAction func Button(sender: UIButton) {
    timer?.invalidate()
}
//=====================FunctionB=========================//

func rand() {
    var yaran = UInt32(bottomConstraint.center.y) - 40
    var xaran = UInt32(topConstraint.center.x) - 40
    square.center.y = CGFloat(arc4random_uniform(yaran)) + 30
    square.center.x = CGFloat(arc4random_uniform(xaran)) + 30
}

func timeUpSegue() {
    performSegueWithIdentifier("GameOver", sender: nil)
    println("Segue: Game Over")
}

func timeIntervalForSquare() {
    timer =  NSTimer.scheduledTimerWithTimeInterval(2, target: self, selector: Selector("timeUpSegue"), userInfo: nil, repeats: false)
}


func animateSlide() {
    UIView.animateWithDuration(0.7, animations: {self.rand()}, completion: nil)
}


}

UIView＆＃34; Square＆＃34;是动画的正方形。如果有人可以将这些代码插入到Xcode中（有或没有那行代码我旁边有评论），看看有什么不对，我会非常感激。

如果代码有点乱，我道歉，我会尽力保持井井有条。

感谢所有能帮助我的人！

Swift：UIView没有使用NSTimer动画进行转换来纠正CGPoints
