获取格式奇怪的 NSDictionary 值

Question

var nsarray:[NSMutableDictionary] = [["object":["uid":["age":"26","gender":"male"]]]]

print(nsarray[0]["object"])

看起来是这样的。我想获得值 "uid"，所以当它打印时它只是 "uid"。当前正在打印：

"uid":["age":"26","gender":"male"]

Answer 1

I want to get the "uid" value. Meaning when it prints it is just "uid". "uid" is a placeholder for a unique ID so I won't know what the uid is.

看起来 "object" 键包含另一个字典，它只有一个元素。要获取第一个密钥，请调用 allKeys 获取密钥，将它们转换为 Array，然后选择初始元素：

let d = nsarray[0]["object"] as! NSDictionary
print(Array(d.allKeys)[0])
