Iphone 网格问题中的砖块

在开始提问之前，让我先用砖块解释一下这个概念

这个游戏是一个益智游戏。我有一个网格是6x6。除了一个方格外，所有方格上都有砖块。游戏开始时，空方块总是从5x5开始，原因是砖块只有在旁边有空方块时才能移动。他们移动的方向是朝向空的正方形。换言之，他们将在触摸后用空方块交换位置。你可以说，运动和视觉部分看起来几乎像滑块图片游戏。但游戏的概念是不同的

我的第一个问题是，出于某种原因，我只能朝一个方向移动砖块。我应该能把它们向上、下、左、右四个方向移动。我与NSLog进行了检查，发现只有屏幕上的UIImage更新到新位置。不是代码中的实际位置。换句话说。。。代码似乎认为，即使在屏幕上的砖块移动到另一个正方形后，砖块仍处于开始位置。更新代码内部位置的最佳方法是什么，以便我可以移动到四个方向中的任何一个

我的第二个问题是，当我检查NSLog时，位于网格上4x5位置的砖块（位于空正方形的左侧）似乎以一个的价格获得了两个位置。这会导致砖块迷失方向，无法正常移动，这只是一步。砖块只能得到一个位置，即x=4y=5，而不是x=4y=5，x=5y=5。我已将问题定位到网格上的空白区域。没有它，砖块运动就很好。既然空方块是游戏的一部分，有没有办法解决这个问题
