重新排序 NSDictionary 数组

Question

如何通过 "ordinator" 键重新排序这种格式的 NSDictionary 数组？

我需要按 "ordinator" 键重新排序以在 table 中显示它们。在其他带有对象的数组中，我使用 class 属性进行排序。我可以做类似这个数组的事情吗？

            LogDataInclusao = "17/05/2017 15:3:23";
            LogNome = "Breno Bohm";

Answer 1

是的，你可以用同样的方式对字典数组进行排序，只需要使用 subscript 而不是 property 访问。

使用包含字符串值的键对数组进行排序

let sortedArray = yourArray.sorted { [=10=][yourKey] as? String ?? "" < [yourKey] as? String ?? "" }

使用包含整数值的键对数组进行排序

let sortedArray = yourArray.sorted { [=11=][yourKey] as? Int ?? 0 < [yourKey] as? Int ?? 0 }

注意： dictionary 中没有 ordinator 键，所以只需将 yourKey 替换为 key 即可你想对数组进行排序。

Answer 2

您可以在 Objective C 中实现此目的，如下所示：

ordinatorDescriptor = [[NSSortDescriptor alloc] initWithKey:@"ordinator" ascending:YES];
sortDescriptors = [NSArray arrayWithObject:brandDescriptor];
sortedArray = [myArray sortedArrayUsingDescriptors:sortDescriptors];
