通过Groovy中的地图循环？(Loop through Map in Groovy?)

 我有一个非常简单的任务，我想在Groovy做，但似乎无法让它工作。 我只是试图在groovy中循环遍历一个map对象，并打印出关键字和值，但是这个代码不起作用。 
 
//A simple map
def map = [
           'iPhone':'iWebOS',
           'Android':'2.3.3',
           'Nokia':'Symbian',
           'Windows':'WM8'
           ]

//Print the values 
for(s in map) {
    println s + ":" + map[s]
}
 
 我试图让输出看起来像这样： 
 
iPhone:iWebOS
Android:2.3.3
Nokia:Symbian
Windows:WM8
 
 有人请详细说明如何做到这一点吗？ 

I have a very simple task I am trying to do in Groovy but cannot seem to get it to work. I am just trying to loop through a map object in groovy and print out the key and value but this code does not work.
 
// A simple map
def map = [
        iPhone : 'iWebOS',
        Android: '2.3.3',
        Nokia  : 'Symbian',
        Windows: 'WM8'
]

// Print the values
for (s in map) {
    println s + ": " + map[s]
}
 
I am trying to get the output to look like this:
 
iPhone: iWebOS
Android: 2.3.3
Nokia: Symbian
Windows: WM8
 
Could someone please elaborate on how to do this??
