swift-将NSArray中字典的值放入数组中

我有一个NSArray，里面有这样的字典：

{
    count = 7;
    week = 4;
}

{
    count = 9;
    week = 5;
}

weeks = [4, 5]
count = [7, 9]

如何将NSArray中的这些字典转换为两个如下所示的数组：

{
    count = 7;
    week = 4;
}

{
    count = 9;
    week = 5;
}

weeks = [4, 5]
count = [7, 9]

我尝试过：

let array=array（arrayLiteral:results.valueForKey（“month”））

但是把这个拿回来

[(
    4,
    5
)]

谢谢

您可以使用flatMap并将其条件转换为Int来提取字典值，如下所示：

let nsArray = NSArray(array: [["count":7,"week":4],["count":9,"week":5]])

let weeks = nsArray.flatMap{$0["week"] as? Int}
let count = nsArray.flatMap{$0["count"] as? Int}

print(weeks)  // "[4, 5]"
print(count)  // "[7, 9]"
