Changing backgroundColor in Swift, Xcode 6
提问by Frank Barrett
I know the code to change the backgroundColor in iOS is something to this extent:
我知道在 iOS 中更改 backgroundColor 的代码是这样的：
self.view.backgroundColor = UIColor.yellowColor()
But for some reason, I am getting an "Unexpected declaration" error.
但出于某种原因，我收到了“意外声明”错误。
Anybody know why?
有人知道为什么吗？
This is the file I am dealing with, ViewController.swift. It is literally just a new single-view app template from Xcode 6.
这是我正在处理的文件 ViewController.swift。它实际上只是来自 Xcode 6 的一个新的单视图应用程序模板。

You put your code in the wrong place.
你把代码放在错误的地方。
class ViewController: UIViewController {
// This space is only for declarations.
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
// Put this setup code in the viewDidLoad method.
self.view.backgroundColor = UIColor.yellowColor()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
