我在
Swift(XCode 6.2)中制作了一个非常简单的单视图应用程序,它包含2个按钮“blackButton”和“whiteButton”.点击blackButton后,将View的背景颜色更改为Black,单击whiteButton后,将背景更改为白色.任何人都可以提出任何可能的方法来做到这一点吗？
ViewController.swift：
//beginning
import UIKit
class ViewController: UIViewController {
@IBAction func blackButton(sender: AnyObject) {
}
@IBAction func whiteButton(sender: AnyObject) {
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
