ios8 - Swift use String as Dictionary Keys -

-

i don't know if possible ... have code 

var dic = dictionary<string, string>() var string = [button1, button2, button3]  @ibaction func button(sender: anyobject){ dic["\(string)"] = "0" }

the result in dic 

[button1, button2, button3]:0

but want :

[button1:0, button2:0, button3:0]

how can do?

from apple swift dpcs example doc:

var airports: [string: string] = ["yyz": "toronto pearson", "dub": "dublin"]

this definitly, access:

var key = "dub" var val = airports[key] var val2 = airports["dub"]

means have use steink directly access value :-)
