我知道这是个愚蠢的问题。 我正在开发一个益智游戏，代码就是：
import UIKit
class ViewController: UIViewController {
var allImageViews : [UIImageView] = []
var allCenters : NSMutableArray = NSMutableArray()
var emptySpot : CGPoint = CGPoint()
var originalCenters : NSMutableArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
// Center point for piece of image for iPhone 5S simulator
var xCen : CGFloat = 53
var yCen : CGFloat = 53
// arrangement of 3*3 piece of images
for v in 0...2{
for h in 0...2{
var pieces = [[0, 1, 2], [3, 4, 5], [6, 7, 8]]
let filename = String(format: "Smile_%02i.gif", h+v*3)
let Image = UIImage(named: filename)
let myImageView = UIImageView(image: Image)
var curCenter : CGPoint = CGPointMake(xCen, yCen)
//adding centerpoint to allCenter array
allCenters.addObject(NSValue(CGPoint : curCenter))
myImageView.frame = CGRectMake(0, 0, 106, 106)
myImageView.center = curCenter
myImageView.userInteractionEnabled = true
//adding all Images in array allImageviews
allImageViews.append(myImageView)
self.view.addSubview(myImageView)
//Increment on X-Axis
xCen += 106
}
//again sex X centerpoint to 53
xCen = 53
//Increment on Y-Axis
yCen += 106
}
// romove one piece at index 0
allImageViews.removeAtIndex(0).removeFromSuperview()
// we have all 8 imageview and all 9 centerpoints
self.randomizeBlocks()
}
// placing the piece of images randomly
func randomizeBlocks(){
// new array that copy centerpoint from allCenters
var centersCopy: NSMutableArray = allCenters.mutableCopy() as NSMutableArray
var randLocInt : Int
var randLoc : CGPoint
// loop for all peice of images saved in allImageViews
for i in allImageViews {
//Place Images randomly
randLocInt = Int(arc4random()) % centersCopy.count
randLoc = centersCopy.objectAtIndex(randLocInt).CGPointValue()
i.center = randLoc
centersCopy.removeObjectAtIndex(randLocInt)
}
// for finding empyblock which is at index 0
emptySpot = centersCopy.objectAtIndex(0).CGPointValue()
}
var leftisEmpty : Bool = Bool()
var rightisEmpty : Bool = Bool()
var topisEmpty : Bool = Bool()
var bottomisEmpty : Bool = Bool()
// touch event
override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {
var topCen : CGPoint
var left : CGPoint
var right : CGPoint
var top : CGPoint
var bottom : CGPoint
let touches = touches.allObjects as [UITouch]
var myTouch = touches.first
if let myTouch = myTouch{
topCen = myTouch.view.center
// movement to empty block
left = CGPointMake(topCen.x - 106, topCen.y)
right = CGPointMake(topCen.x + 106, topCen.y)
top = CGPointMake(topCen.x, topCen.y+106)
bottom = CGPointMake(topCen.x, topCen.y-106)
// Deciding which side is empty
if emptySpot == left{
leftisEmpty = true
}
if emptySpot == right{
rightisEmpty = true
}
if emptySpot == top{
topisEmpty = true
}
if emptySpot == bottom{
bottomisEmpty = true
}
if leftisEmpty || rightisEmpty || topisEmpty || bottomisEmpty{
UIView.beginAnimations(nil, context:nil)
UIView.setAnimationDuration(0.5)
myTouch.view.center = emptySpot
UIView.commitAnimations()
emptySpot = topCen
leftisEmpty = false
rightisEmpty = false
topisEmpty = false
bottomisEmpty = false
}
}
}
}
现在我被困在用户完成整个画面的时候我怎么能比较所有图像的位置，所以应该出现警告信息并说'＃34;游戏已经完成＆＃34;。我已经没有＆＃39;我知道怎么能这样做。
请帮我完成这个游戏。
提前致谢。

你应该有一个3x3阵列，它保存每个位置当前拼图的编号。最初，这将是
var pieces = [[0, 1, 2], [3, 4, 5], [6, 7, 8]]
其中0表示空白点。每次移动拼图时更新该阵列，例如，
当＃3件向上移动时
pieces = [[3, 1, 2], [0, 4, 5], [6, 7, 8]]
如果pieces再次等于初始数组，游戏就完成了。

您的代码有变更和解释： -
override func viewDidLoad() {
super.viewDidLoad()
........YOUR CODE......
//READ below.......
var tagValue: NSInteger = 0 //change it as me typing directly in post.
var imageDict: Dictionary<String, String> = [:]
var posStateDict: Dictionary<String, String> = [:] //Change it as per swift format.
var frame: CGPoint = CGPointZero
for v in 0...2{
for h in 0...2{
........YOUR CODE......
//......UPDATED.......
//Now you should also add a tag value to your imageView
myImageView.tag = tagValue
myImageView.userInteractionEnabled = true
frame = CGPointMake(xCen, yCen)
imageDict.setValue(NSStringFromCGPoint(frame), forKey: NSString.stringWithString("/(tagValue)"));
posStateDict[NSString.stringWithString("(d)")] = ["false"]
tagValue = tagValue + 1; //Incrementing tagValue.
}
........YOUR CODE......
}
........YOUR CODE......
}
// touch event
override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {
........YOUR CODE......
if leftisEmpty || rightisEmpty || topisEmpty || bottomisEmpty{
........YOUR CODE......
//READ below.......Rest code here.
//Here you need to get that imageView object which is moved.
//From that imageView you need to get tag value.
//With the tag value you could search it's orignal frame from the imageDict and compare the frame of it.
//If frame match then set their respective object true in posStateDict dictionary.
//Now check this dictionary if all true and no false then game is over.
}
}
}
}
很抱歉，由于有一些工作，我无法为该部件编码。希望这个解释能帮到你。

也许将原始imageView中心保存在一个数组中，然后将其与新位置进行比较？
