我正在尝试向现有应用添加选择器视图。但是，我遇到了麻烦。我仍然是Swift的新手，我不知道如何描述这一点，但希望你能够理解下面的内容，并提出相应的问题来解决这个问题。
我得到的错误信息是＆＃34;致命错误：索引超出范围＆＃34;从行：
cell.txtField_PickData.text = self.arrayTemprature[indexPath.row].valueForKey("tempValue") as? String
myTitleArry等于两个输入＆＃34;气温＆＃34;或＆＃34;水温＆＃34;
以下是此错误的代码部分。如果需要更多代码来帮助确定问题，请尽快提供：

更新： 我删除了标题数组，只是添加了另一个动态单元格并分离了驱动这两个数据的数据。
标题超出范围的索引会消失，但现在会为该行创建相同的错误：
cell.txtField_PickData.text = self.arrayTemprature [indexPath.row] .valueForKey（＆＃34; tempValue＆＃34;）as？串
此功能不需要额外的行，所以现在我想知道错误是否与数组收集数据的方式有关。
我添加了大部分代码。不得不减少一些以达到30k的限制。
答案 0 :(得分：1)
您的问题导致错误的numberOfRowsInSection实施。
告诉数据源返回给定部分中的行数 表视图。
请注意此方法并进行所需的所有更改，以便为数据源提供所有可能的变体。
在这里你可以看到一个例子：
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let count = self. myTitleArray?.count as Int {
return (count)
} else {
//myTitleArray is nil, so just return 0
return 0
}
}
更新 :(在您对主要问题进行新修改后）
似乎有错误： 第1节单元格有6个元素，但您已声明：
private let NumberOfRowsInSection1: Int = 5
更多详情：
您的问题很典型：＆＃34;索引超出范围＆＃34;，这是什么意思？你的数组，在这种情况下，self.arrayTemprature在语句中不需要索引，例如，如果你有一个包含3个元素的数组，并且你请求第4个元素，那么你将会看到错误。但是当你没有初始化你的数组并且假装请求一个不完整的元素时（你的数组是nil而你总是想要第4个元素：index超出范围），也会发生这个错误。因此，从它的声明，初始化，使用断点开始检查你的self.arrayTemprature，并检查你为什么会遇到这个错误。
