我的代码运行了大约3秒，然后挂起，就像我不能再滑动一样(还有另一个脚本被分配用于滑动)。然后大约再过5秒，我的应用程序就崩溃了。这有什么问题吗？

你正在进入无限循环。
以下是问题所在：
yield return StartCoroutine (Start ());当你执行yield return StartCoroutine (Start ())时，它会启动新的协程，然后等待完成旧的协程(这永远不会发生)，然后它会在第一个协程运行的时候启动另一个协程。
您在yield return StartCoroutine (Start ())之后拥有的yield break;将不会被调用甚至。您可以通过将Debug.LogWarning("Finished coroutine!");放在该yield break;之后来证明这一点。该Debug.Log消息将永远不会显示。
这里最大的问题是这些协程都没有真正停止。然后他们yield启动另一个，然后等待那个完成，然后启动另一个。正因为如此，您可以轻松地运行数千个协程。
要解决这个问题，必须做两件事
1.Remove yield return，所以协程实际上可以退出。
因此，请使用StartCoroutine (Start ());而不是yield return StartCoroutine (Start ())。
the StartCoroutine (Start ());之前的2.Put yield return null;。您必须这样做，因为如果Start()协程中的所有逻辑(如while (Input.location.isEnabledByUser) )都无法运行，则不会有让步/等待，您将再次得到无限循环。
对你的loadTiles协程做同样的事情。
