用字典中的数据填充 UITableView [英] Populating a UITableView with data from a dictionary

问题描述

我只是想做的是用来自预先存在的 [String:String] 字典的数据填充我的表视图.我找到了无数关于如何使用数组执行此操作的示例和教程，但没有找到关于如何使用字典执行此操作的示例和教程.字典值以什么顺序放入 tableview 对我来说无关紧要.

what I am simply trying to do is populate my table view with data from a preexisting [String:String] dictionary. I have found countless examples and tutorials on how to do this with an array, but none on how to do it with a dictionary. It does not matter to me in what order the dictionary values get put in the tableview.

我有一个单独的 UITableViewCell 类，它有到我的单元格的出口，我只需要找出如何将这个字典链接到表视图.非常感谢任何和所有帮助，谢谢.

I have a separate UITableViewCell class that has outlets to my cell, and I just need to find out how to link this dictionary to the table view. Any and all help is greatly appreciated, thank you.

推荐答案

因为你永远不能保证你的字典内容会按照它进入的顺序出现，你不能直接从字典中完成.因此，您需要使用基于字典键的单独数组(例如)间接执行此操作.

Because you can never guarantee that your dictionary contents will come out in the same order it went in, you cannot do it directly from a dictionary. Therefore you would need to do it indirectly using a separate array that is based on the dictionary keys (for example).

这样做的一种方法是根据字典的排序键创建一个数组:

One such way of doing this would be to create an array based on the sorted keys of the dictionary thusly:

sortedKeys = Array(dictionary.keys).sorted(<)

然后在您的 UITableView 委托/数据源方法中使用 indexPath.row 作为 sortedKeys 数组的索引来获取数组的键.然后使用该键从字典中获取值.

Then in your UITableView delegate/data-source methods use indexPath.row as index to the sortedKeys array to grab a key the array. Then use that key, to grab the value from your dictionary.
