“Expected Declaration” Error in Swift in userDefaults

问题

I am trying to save the placeHolderValue in NSUserDefaults, but I am getting an expected declaration error in the third line.

 let placeHolderValue = 1000
 var userDefaults = NSUserDefaults.standardUserDefaults()
 userDefaults.setValue(placeHolderValue, forKey: "placeholder")
 userDefaults.synchronize()

I've looked everywhere and can't find someone with a similar problem. What am I doing wrong? Thanks!

回答1:

I think I didn't have the code above within a function. Once I placed it inside a function within my class declaration everything ran smoothly:

func test() {

    let placeHolderValue = 1000
    var userDefaults = NSUserDefaults.standardUserDefaults()
    userDefaults.setInteger(placeHolderValue, forKey: "placeholder")


    }
