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.
- }
- }
