Ios 对NSDictionary数组重新排序

如何按“ordinator”键对NSDictionary数组按此格式重新排序

我需要按“ordinator”键对它们重新排序，以便在表中显示它们。在其他包含对象的数组中，我使用sort来使用class属性进行排序。我可以做类似于此阵列的操作吗

是的，您可以按照相同的方式对字典数组进行排序，只需使用

下标

而不是

属性

访问即可

带有键的排序数组包含字符串值

let sortedArray = yourArray.sorted { $0[yourKey] as? String ?? "" < $1[yourKey] as? String ?? "" }

让sortedArray=yourArray.sorted{$0[yourKey]作为？字符串？？“<$1[yourKey]作为？字符串？？”

带键的排序数组包含整数值

let sortedArray = yourArray.sorted { $0[yourKey] as? Int ?? 0 < $1[yourKey] as? Int ?? 0 }

让sortedArray=yourArray.sorted{$0[yourKey]as？Int？？0<$1[yourKey]as？Int？？0}

注意：您的

字典中没有
排序符
键

，因此只需将

您的键

替换为

键

，即可对数组进行排序。

，即可对数组进行排序。

您可以在目标C中实现以下目标：

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

您可以在目标C中实现这一点，如下所示：

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